arduino-esp8266-alexa-multiple-wemo-switch's Issues

Cannot add to Wemo app

I tried adding the emulated Wemo switch in Wemo Android app. But it did not work. Any ideas?

Exception (9): crashing

Anyone else having trouble with this crashing?

I'm using a nodemcu board, and randomly it will just crash and dump a load of stuff in the serial monitor.

Tried multiple boards with the same outcome.

I can't seem to install the stack decoder on my arduino IDE running windows, any help would be great.

Best regards

Strange issue with discovered devices

Hi,
My Echo Dot is able to find devices, reflects clearly in Alexa app and debug window. When i try calling for power on or off Alexa tells me sorry no device registered with this name for at least 2 out of 6 switches, sometimes more.

In case some device does not get registered in first search and i search again it registers correctly but either the switch last added or one or more switches added previously give that response.

It's not issue but want to know how to add 2 more ssid and password? Is it possible?

Crash when more than 11 devices

Hi there
And thanks for a great code .... Compilation was working 1.st time with the onboard diodes.

One question ...... When i compile with 11 devices it goes ok every time....
(heres the connect log)

BUT
When I compile with 12 devices the witty esp8266 reboot every 10 second.
It connect to wifi... and the reboot after 5 sec.

When i compile with 13 devices the witty esp8266 won't connect to wifi
and roboot every 5 second.

Same goes with devices up to 14 and over. (I could really use 20)
(I have a 100uf over the 3.3V supply for stability)

Have you seen this issue before, or have any idea of what is going wrong ?
Thanks in advance.

Relay

Hi

I'm wanting to use the relay as a pulse relay. is there anyway to make the code switch the relay on for say 1 second and then back off again without confusing alexa?

Any help would be great.

Thanks

Unintended (emulated WeMo switch) activity if going to the Alexa Web App - Smart Home - Devices page

Sorry, you may have already addressed this issue. I will look at your advice in this thread #25

Kakopappa, I am using your WeMo switch emulated code as the base code for a solution I developed for people with limited mobility. I provide them with the ability to voice control their hospital beds, because for them there is no other alternative. Everything necessary to make this work is my time and money as part of a volunteer effort.

I noticed some undesirable behavior and I am wondering if this is something you also noticed and if you thought of a solution for it. (Nassir may have already contacted you regarding this, so sorry if this is duplicate)

In my solution, I have 4 WeMo emulated switches that control 4 movements of the bed. In my lab, when I discover devices I see those devices in the Devices webpage within the Amazon\Alexa web app. The issue is anytime I either open the Devices web page, or refresh the Devices web page, or click Discover in the Devices web page all 4 relays cycle on and off. The downside of this is unintended bed motion creating a possible safety issue.

Looking at the Serial Port log, I think I see the cause but I have not figured out what to do about it. Associated with the Unintended switch cycling is a GetBinaryState message that will happen when you simply open the Devices web page, or refresh the Devices web page, or click Discover on the Devices webpage . Associated with the desired switch activity is a SetBinaryState message. I contacted Amazon but don't see them doing anything about it. I also contacted WeMo just in case their engineering team had to deal with this already since testing with a physical WeMo switch does not exhibit this same behavior.

Here are some snippets from the serial port for a few scenarios -

This is what a Voice Command for Turn on relay 2 looks like: (This is desirable behavior)

And here is what it looks like when you click discover new devices for the same switch even when the devices are known and online (Undesirable)

Discovery change?

I was tweaking a branch of this code last night when suddenly Alexa stopped discovering the device. She won’t discover or control my garage door now either which has been running perfectly stably for several weeks. Discovers other skill changes (like sinric). Did amazon change something 12 hrs ago?
I haven’t switched debug messages on to narrow the problem down yet...

Alexa won't find more than 5 switches...

If I define more than 5 switches, Alexa randomly fails to discover some of them. All the switches I have defined work fine idenpendanty, but discovery of all of them is a problem. The code says "max 10" - what limit is this, and have I hit it early?

Basic lack of understanding. GPIO 0 until GPIO 8.

It lies hidden in my mind, as I can address the "WeMos D1 mini" PIN D0 to D8 in the example wemos.ini to perform switching functions.
Since 3 days, after the purchase of an Amazon Echo Dot, I now deal with the topic of signal exchange.
At Sinric.com I opened an account and defined a switch. I got the sketch wemos.ini running on the "WeMos D1 mini" and Alexa recognizes the two switches specified in the example. When I talk to Alexa I can see in the monitor that the two switches are also switched on or off.
Only which PIN of the "WeMos D1 mini" is behind it? Nothing happens at the exits. In the sketch I also find no definition of an OUTPUT. Have I overlooked something fundamental?

Not an issue......multiple wemo with dynamic wifi credentials and socket configurations

Dear bro...

i ve used your source code of multiple wemo and added android ap code for configuring wifi name pass code and also to configure switches dynamically..

here is the brief description of code i ve developed

1. Waits for wifi connection during attempt GPIO blinks every 1 sec untill 60sec (60sec because if power failure then my wifi router takes around 50sec to restore with good wifi (i beleive it is same in most cases))

2. if connection is unsuccessful after 60seconds then GPIO permanently goes off and ap mode auto starts, as shown in below figure

   

3. now take your mobile and trun on wifi and connect to the name "BUBBLES".. refer screenshot below
   

4. connect to ip as mentioned in 2nd step uart log. the mobile screen will look like below
   

5. and "Submit" thats it.. wifi id and password will be saved in EEPROM and everything will work fine..

6. when power reset wifi will get auto connected with ID and password read from EEPROM of ESP8266. and GPIO will be on continuously when wifi is connected "symbol of successful wifi connection"

7. if you dont want 5 smart switches then leave blank "configure socket name text box". if you leave blanck then switch will not be configured anymore.

Enjoy the code (cheers to kakopappa) - if you want to buy a beer buy for him... 👍

Sometimes it re-initializes sometimes it doesn't. Any idea what this error means?

Seems related to #13

General info Request

First, thanks for producing some excellent pieces of software.
I run your single Wemo switch software on several esp devices - and it works Flawless!!
24 hours for a month and the esp8266 units and Alexa continue to work great.

Now, I was looking at your latest multiple wemo software and have a few questions:

Multiple wemo switch:

1. I am not sure I understand how I use this. Your new software allows one to add several (14) device names and address but It is not clear to me how I would utilize it. On your single switch if i have a device name" box" and tell Alexa to turn box on/off and it does. I assign the output pin and it controls a relay or led etc... perfect!
   In the multiple switch I can add several(14) device names with each having a new name and port.
   If I were to tell Alexa the device name - say Turn on "Office" or Kitchen etc, What device and or pins does it control...

2. I don't understand how the software controls each device output pin ? and where I put the info.

3. There are several files beside the .ino file, where do I put these in order to have the ide compile?
   As is I get errors when trying to compile.

I guess I need a kick start to get me going on the project....

Thanks for your help

Joe

Switch

How can i add some switches to use without Alexa?

After a copple time its "restarting" the system and my lamp goes on again..?!

How could I fix it?

Where are the Wemos output pins defined?

I see the port numbers in the wemos.ino file, but I don't see where the specific GPIO pins are defined. Where do I find the D1..outputs defined?

Works for a few minutes, then Alexa loses connection to device

I have successfully integrated this method into some of my existing Wemos code, and it works well. I have two devices connected to one Wemos, it boots up and connects to Wifi, I also have MQTT talking to a Pi, then the Alexa connection is successful. Alexa will function the devices on command, no problem. Then I leave and come back some time later, and find that while the Wemos is still connected to Wifi, Alexa no longer sees the devices.
I am about to look into just getting Alexa to connect to my Pi as one device and just relay commands from that server. Any ideas? I am implementing the code just like the example. Thanks in advance!

Using only one WebServer

Hi

First of all thanks for your effort to integrate our beloved ESP8266 "into Alexa framework"!
I integrated your code into my current project. Unfortunately I ran out of heap using your files.
As I dont have an Echo yet I cannot try it for myself but I have a suggestion:
My Project already uses a WebServer, so I dont think that It is necessary to start some more for every device. Wouldn't it be easier to respond to the UDP Broadcast (respondToSearch) with a different URL depending on the number of the device: for example:

"LOCATION: http://" + String(s) + ":" + String(localPort) + "/setup1.xml\r\n"
"LOCATION: http://" + String(s) + ":" + String(localPort) + "/setup2.xml\r\n"
...

And for the callback registration:

server->on("/setup1.xml", [&]() {
    handleSetupXml1();
  });
server->on("/setup2.xml", [&]() {
    handleSetupXml2();
  });
...

And for the events:

"<controlURL>/upnp/control/basicevent1</controlURL>"
"<controlURL>/upnp/control/basicevent2</controlURL>"
...

 server->on("/upnp/control/basicevent1", [&]() {
    handleUpnpControl1();
  });
 server->on("/upnp/control/basicevent2", [&]() {
    handleUpnpControl2();
  });

With some little adaptions for handling the number of course, but you get the idea.

Would this work or does the Belkin skill only accept setup.xml, /upnp/control/basicevent1 and nothing else ??

regards
Erich

Not an issue , Did i's possible over ifttt ou other thing to use it via Google Home : I'm frensh

Hi everyone (My english is bad :) it's normal i'm frensh)
So i try to do it working with Wemo app but it's not work
So i want to now if it's possible via IFTTT or other things

Thanks for replies

Does hot handle GetBinaryState message

The Alexa app allows control of devices. It sends a GetBinaryState message to find the current status. This is erroneously interpreted as a switch ON command. Please add handler for GetBinaryState messages. Format of request is same as SetBinaryState message.

Relevant Alexa bug? Discovery problems...

This may be root the cause of my Alexa not finding >5 switches yesterday .

After a few hours of quite intensive device discovery, my Alexa stopped finding any new devices . I could see XML being uploaded from the multiple switch code when the discovery was underway , but Alexa app didn’t display any result. Put the code onto a new esp-01 with the same result.
In desperation I reset the echo speaker and tried discovery again. Alexa then had 2 copies of each switch ! Looks like discovery was happening all along , but that the results weren’t being saved somewhere.

boot error

As mentioned code is working fine but i'm getting this type of error in serial monitor
Board used: NODEMCU ESP8266-12F

Device appears to be malfuctioning.

Hi! I have an amazon echo gen 2 and I was using this code with an esp for my light. Everything was working quite good but after each succesfull command Alexa was late responding Ok (or "I'm not sure what went wrong" although nothing went wrong!!!).

Yesterday the firmware of Alexa was updated to 599472520. The commands are still successful issued and the relay opens and closes as it is supposed but most of the times the always late response is "this device appears to be malfunctioning".

So there is something wrong with the new firmware update and the status report that we send to Alexa.

Similar problem after the update I have with the espalexa code where when I set a light to off Alexa responds that this value is not supported by the device!!! Just before the update it worked perfectly...

ESP (NodeMCU) crashes when adding the 4th switch...

Hello!
First of all: thank you very much for sharing your code with us!!!
Unfortunately I'm facing a serious issue when adding my 4th swith to the code.
3x Switches are running very smooth, but after adding the 4th my ESP crashes with:

Exception (28):
epc1=0x40203bfb epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000000 depc=0x00000000

Is it possible that there is an issue with heap consumption?
I'm starting with:
Adding switch : eins index : 0 => loop heap size: 21248
Adding switch : zwei index : 1 => loop heap size: 21296
Adding switch : drei index : 2 =>loop heap size: 21216

and once I enter the loop (): => ... loop heap size: 6584

Any idea what could cause that crash after adding the 4th switch?

How to make the state returned to Alexa from another gpio pin.

Lots of success with this code today after changing the persistent_uuid line in switch.cpp as pointed out by others. That's really helpful guys, thanks.
My Alexa Plus is discovering the devices without any additional skills, and controlling the resulting relays just fine.

My use case is a garage door control, that wants 1 sec pulses to either open or close the door. I have modified the code in this repo to read a gpio input pin on the esp2866 that is connected to a switch so I know the state of the door. Simple then to gate the Alexa on and off commands via that garageDoorState Boolean to only produce a close pulse when the door is open and vice versa.

The only problem with this, is that Alexa doesn't know the actual state of the door, only the state of the door control relays , and as they are always short pulses, when I look at the belkin smart switch device display in Alexas list of devices, it's always off.

Where in the code could I make changes such that the state of the door is returned to Alexa instead of the state of the door controls? I would like to see those smart switch displays in Alexa say "on" when the door is open. (This could be really useful if I ever want to know remotely if I have left the door open)

I can see regular " got binary state request" messages in the serial monitor which is probably where I need to make changes, but I lack the understanding of exactly how...

Apart from the tweak above, and removing most of the debug messages to make life quieter, I haven't touched the library files (yet).

hi, i am trying to either add a new switch or rename an existing switch, however whatever i try, the code refuses to compile, and jut returns an undefined reference to the item i m trying to add/alter!

i dont have issues with switching the devices already added, i just want to customise it to my requirements.

please any help would be greatly received, and stop me from actually going insane!!

thank you in advance

Not an issue - a question

New to the esp2866, and to alexa , but keen to learn a bit about both by playing with an integration between the two.
My esp2866's are en route from china, and my brand new echo plus is awaiting something real to interface to.
Is anyone succefully using this code or similar to interface to alexa using just the Wemo skill? I won't be able to use sinric as it not a released skill in NZ. Also not keen on building the Home automation stack at present.
Thanks in advance.

Status of switch "On" reported after power up

I think this just needs
bool switchStatus = false;
inserted in Switch class definition

Combining with WiFiManager library doesn't work

Hi!
I'm trying to combine your precious library with one built in Arduino called WiFiManager. It seems quite easy but whatever I do it doesn't want to work. My serial monitor ends on:
"Begin multicast ..
Udp multicast server started at 239.255.255.250:1900
WebServer started on port:
90
WebServer started on port:
91
Adding switches upnp broadcast responder
Adding switch : floor white index : 0
Adding switch : floor color index : 1"

And that's it. It won't respond to Alexa devices discovery. And I have no idea what is wrong, because without WiFiManager it works perfectly. But I need some easier way to configure WiFi parameters that uploading a sketch every time. So I would be very grateful if you could spend some time checking what might be wrong with combining those two libraries together. Is it something that I do wrong or is it some problem with libraries incompatibility?

My actual code looks like that:

// WiFiManager libraries
#include <ESP8266WiFi.h>          //https://github.com/esp8266/Arduino
#include <DNSServer.h>
#include <ESP8266WebServer.h>
#include <WiFiManager.h>          //https://github.com/tzapu/WiFiManager

#include "UpnpBroadcastResponder.h"
#include "CallbackFunction.h"

// for manual config start
#define CONFIG_PIN 0

//for LED status
#include <Ticker.h>
Ticker led;

void Blink()
{
  //toggle state
  int state = digitalRead(BUILTIN_LED);  // get the current state of GPIO1 pin
  digitalWrite(BUILTIN_LED, !state);     // set pin to the opposite state
}
// LED status end

// Alexa wemo
// prototypes
boolean connectWifi();

//on/off callbacks
void floorwhiteOn();
void floorwhiteOff();
void floorColorOn();
void floorColorOff();

void floorWhiteOn() {
  digitalWrite(16, LOW);
  Serial.print("Switch 1 turn on ...");
}

void floorWhiteOff() {
  digitalWrite(5, HIGH);
  Serial.print("Switch 1 turn off ...");
}

void floorColorOn() {
  digitalWrite(5, LOW);
  Serial.print("Switch 2 turn on ...");
}

void floorColorOff() {
  digitalWrite(5,HIGH);
  Serial.print("Switch 2 turn off ...");
}

UpnpBroadcastResponder upnpBroadcastResponder;

Switch *floorwhite = NULL;
Switch *floorcolor = NULL;
// Alexa end

//gets called when WiFiManager enters configuration mode
void configModeCallback (WiFiManager *myWiFiManager) {
  Serial.println("Entered config mode");
  Serial.println(WiFi.softAPIP());
  //if you used auto generated SSID, print it
  Serial.println(myWiFiManager->getConfigPortalSSID());
  //entered config mode, make led toggle faster
  led.attach(0.2, Blink);
}

void setup() {
  
  Serial.begin(9600);
  pinMode(BUILTIN_LED, OUTPUT);
  pinMode(16, OUTPUT); // D0
  pinMode(5, OUTPUT); // D1
  pinMode(CONFIG_PIN, INPUT); // set pin 0 (D3) as input for setup mode
  
  // start ticker with 0.5 because we start in AP mode and try to connect
  led.attach(0.6, Blink);

  //WiFiManager
  //Local intialization. Once its business is done, there is no need to keep it around
  WiFiManager wifiManager;
  //reset settings - for testing
  //wifiManager.resetSettings();

  //set callback that gets called when connecting to previous WiFi fails, and enters Access Point mode
  wifiManager.setAPCallback(configModeCallback);

  wifiManager.setConfigPortalTimeout(300); // 5 minutes timeout for setup mode

  //fetches ssid and pass and tries to connect
  //if it does not connect it starts an access point with the specified name
  //and goes into a blocking loop awaiting configuration
  if (!wifiManager.autoConnect("Enterius_Switch")) {
    Serial.println("failed to connect and hit timeout");
    //reset and try again, or maybe put it to deep sleep
    ESP.reset();
    delay(1000);
  }

  //if you get here you have connected to the WiFi
  Serial.println("connected...yeey :)");
  led.detach();
  //keep LED on
  digitalWrite(BUILTIN_LED, LOW);

  // Switches definitions
 
  upnpBroadcastResponder.beginUdpMulticast();

    // Define your switches here. Max 14
    // Format: Alexa invocation name, local port no, on callback, off callback
    floorwhite = new Switch("floor white", 90, floorWhiteOn, floorWhiteOff);
    floorcolor = new Switch("floor color", 91, floorColorOn, floorColorOff);

    Serial.println("Adding switches upnp broadcast responder");
    upnpBroadcastResponder.addDevice(*floorwhite);
    upnpBroadcastResponder.addDevice(*floorcolor);
 
}
  

void loop() {
 
   if ( digitalRead(CONFIG_PIN) == LOW ) {
    led.attach(0.2, Blink);
    //WiFiManager
    //Local intialization. Once its business is done, there is no need to keep it around
    WiFiManager wifiManager;
    wifiManager.startConfigPortal("Enterius_Switch");
    
    
    if (!wifiManager.startConfigPortal("Enterius_Switch")) {
      Serial.println("failed to connect and hit timeout");
      delay(3000);
      //reset and try again, or maybe put it to deep sleep
      ESP.reset();
      delay(5000);
}

}

// Main Alexa Wemos code


upnpBroadcastResponder.serverLoop();
    
    floorcolor->serverLoop();
    floorwhite->serverLoop();

    
  
}

I'm just a beginner so maybe I am making some stupid mistake? I spend a few last days on this and it seems that I can't solve this problem by myself. So please, please help.

Thanks and best regards
Chris

Dimmer Module

Is it possible to add a Dimmer Module to the system, so that you can say "Alexa set the light to 20%"
if yes, could you post an example?

Can you add eeprom- so that the switch state in the memory of ESP incase of blackout

Thanks for this nice work. It helps me a lot. I was using some RF based system in my home. Now I want to replace with ESP and Amazon Echo. In my earlier system I used EEPROM to keep switch state stored in the memory. I was trying to add same codes in your code to have same functionality. But it generates WDT RESET! ESP is continuously restarting. Please help with this.

Alexa SmartHome skill - not finding

Installed on my NodeMCU, went through Alexa app to add... nothing.
So, turns out you need the smart home skill for the devices you want to add.
The WeMo skill requires you to enter your wireless SSID and the WeMo device's MAC address.
This breaks the compatibility with these wemo emulator projects unfortunately.

So, has anyone gotten past this? Is there a generic smarthome skill I'm unaware of?

P.S. I made sure all devices were on the same network and I even reset my Echo Dot. Nothing :/

What do these errors mean and how do I fix them

Project doesn't specify a license

Can you please add a license to your repo so I know whether I can use the code or not in my own projects and with what restrictions. https://help.github.com/articles/adding-a-license-to-a-repository/

What is "functional" library?

Where is I can found this file '#include ' ?
thanks.

setup.xml not declared error

Hi,
I'm getting "Switch.cpp:214: error: 'setup_xml' was not declared in this scope" error when trying to compile. The fix is obvious (I think), but I just want to check if I've pulled down the right version which has the ability to respond to Alexa status requests. Or am I doing something stupid :-)

Thanks

Please find above the request there is no urn for Belkin recevied. Please let me know what was the issue. I am trying with Echo Gen2

Problems running more than 1 instance of this code

I was trying to run 2 instances of this code, on seperate esp-01's so I could test the garage door controller I was building for a friend, whilst keeping my own garage door control going.

The esp-01's were doing dhcp so had unique ip addrees's, I renamed the Alexa invocation words so they were unique , and set the web ports so there was no overlap on the two devices , but I still couldn't make Alexa happy with both of them at the same time.
Eventually had to switch one of them off to get it stable.

Anyone hazard a guess why?

OTA flash

Alexa can't find the devices after an OTA "update". Can this be realised?

Question: WeMo Smart LED Bulbs

Hi
Thanks for a great piece of code...total cool, im using it everyday.

One question, do you plan to implement the WeMo Smart LED Bulbs ?
So it will be possible to dim the bulb, or set anything else to a certain value...volume, or channel up/down ?

Thanks in advance.

randomly disconnecting and reconnecting from wifi

great work with this, i use it almost everyday but the random blue flashing light is getting annoying. when left on for a min or two it spams the serial port with a bunch of random stuff then acts as if it reconnected to the wifi. i'm not sure if its really disconnecting and reconnecting or if its just a bug. it seams like the longer i leave it powered the more it spams.

Wemos multi devices

Hi everyone I call Hasci and thanks for the great program is great. I use a Nodemcu 1.0 and I only have a problem: up to the fourth alexa device recognizes it as soon as I insert the 5th and 6th and 7th so until the alexa slide recognizes only the last 4 devices (example: if I use ports 80 -81-82-83-84-90-91) alexa only recognizes 83-84-90-91 always and only the last 4 devices. I wonder if it happened to you. thank you in advance.

After power cut off ,Alexa says devices not responding

Thanks kakopappa for source code, its working as charm.

After power cut off ,Alexa says devices not responding.
we have to ask Alexa to re discover every timer power off then only we are able to controls the devices.
Is there any fix for this? of workaround (obviously to ask Alexa to discover again) .
Can we send the Setup xml to Alexa with out request from it so that we dont need to ask for discover devices ?

wemo switch over LAN Shield

Hello! kakpopappa! First of all let me thank you for your great work on wemo and on sinric also. Wemo is the easyest way to connect with Alexa without any third party solution!
My problem is that I can't use this code to an Arduino Mega with LAN shield, only on a NODE MCU ESP8266. I need more IO ports than NODEMCU has, and LAN connection also. I prefer LAN connection...
Or it's possible to somehow port this code to use on an Arduino Uno or Mega with LAN shield?
Thank you very much!

Request/Question

Not an issue but wasnt sure how to comment, firstly great job!

Now to the request, is it possible to read the state of a pin using Alexa? for instance if this is connected to a gate and I'd like to know if the gate is open or closed by reading an input if it is high or low
