Martin,
First I want to say thank you thank you for such a great bit of software! I am having difficulty with a script I am trying to create, and I cannot figure out how to do it. I receive a value from another MQTT client into this broker. This value is between 40.8 and 59.2. If the value is greater than 54.5 I want to turn on the relay. If the value is less than 51.7 I want to turn off the relay. I get an error when I load the script, I get an error. My script I'm having difficulty with is as follows:
on topic local $Voltage_topic
do
if $this_data > 54.5 then
setvar $relay_status = 1
gpio_out 14 $relay_status
gpio_out 13 not ($relay_status)
else
if $this_data < 51.7 then
setvar $relay_status = 0
gpio_out 14 $relay_status
gpio_out 13 not ($relay_status)
endif
endif
publish remote $Voltage_topic $this_data
Can you please show me what I am not understanding? Thanks in advance! Steve
Fantastic work - game changer for IOT on MQTT!
Have you tested this on the ESP32 by any chance? It has considerable more system resources so could be more viable.
Thanks.
One more question:
there is in sp_mqtt a configuration that leaves the GPIO1 (tx) and GPIO3 (rx) totally free ? So they can be used as generic I/O by the user on script?
With Sonoff you do not have many pins available :)
Thanks, regards
Marco
I cannot seem to follow your instructions on the README to understand where mqtt_server.h is supposed to go. I keep getting file not found when compiling. When I've linked directly to that file, I get a 'cannot find user_interface.h. Everything else seems to be in the correct directories.
Can you break this down a little easier for someone like me? Thank you.
I am farly new to programming an ESP8266, so it might be a dump question.
Is it possible to flash this firmware to the ESP using PlatformIO?
Brilliant product, thank you very much Martin.
I felt it would be very helpful if there was the ability to configure the WiFi channel that the softAP comes up on. When I bring up esp_mqtt in softAP plus station mode, it causes one device on my WiFi network to drop its network connection. I was hoping one could set a different channel for softAP vs station.
However I've subsequently learned that its a limitation of the esp8266; it has only one radio, so station and softAP will always be on the same WiFi channel. Permanent restriction then.

Hello Martin,
I'm new with esp_mqtt. Thanks to your framework and scripts...I succeed in few hours to toggle the relay on a Sonoff Pow r2 with one of your script example. However, I need to read energy consumption data for my application, using MQTT.
Should I have to configure the UART ? How ?
Do you have an example that could help me ?...using Sonoff Pow would be great.
The Sonoff Pow r2 use the CSE7766. That's all I know.
Best regards
Laurent from Paris
Hi,
I flashed the firmware in the firmware directory onto an esp8266(Wemos D1) using ESP8266 Download Tool and if I use the terminal tools like Putty or Hyperterminal, I am unable to write any script.
Tried with both SPI modes QIO and DIO.
Flash size 32Mbit. Baud rate - 230400
I am getting some continuous symbols on the terminal window and the led on esp is flashing continuously.
It would be great if get some help regarding this.
I am using a windows 10 machine,
hello,
the mqtt borker become not stable after enable the MQTT_server_onAuth,

Hi there,
Your work seems great and just what I was looking for.
As I do not have the skill to build the code myself I am trying to use the pre-built binaries.
Flashing them to my NodeMCU seems to work fine (no error messages etc).
However, the 'open AP with ap_ssid MyAP' (or any other name for that matter) does not seem to show up for me to connect to.
Any guidance in this regard would be much appreciated.
Thanks.
Jan
Is there a way to prevent the telnet console from timing out? Somewhat annoying to have to restart the session.
Thanks.
I am exploring the esp_mqtt features, i found that:

Hello Martin,
May I know how to connect my windows PC to your firmware console using TCP port 7777? I type in my browser 192.186.X.Y:7777 but nothing happens.
Thank you in advance!

I have just tried on ArduinoIDE by default libmqtt.a,
and use mosquitto's clients connect to this mqtt-broker.
I have found that it can connect 10 clients, if more than it will be WDT's restart.
I want to count the number of clients by this mqtt server
for limitation and prevent WDT.
How can I count the number of clients by this mqtt server ?
Thank you.
Awesome project!
Is there any way to set alarms per day in the script? Something like:
setalarm 1 "Fri 20:45"
setalarm 2 "Mon 21:45"
...
And/or to get the current day programmatically in the script? So as to make the choice there.
Thanks

I cannot insert any command !.
I also re-flashed the Sonoff (using last bin files) but it stiil loops :(
Any idea?
I'm trying to do iterations using 'on topic' as recursive function.
So it is possible that the script (wrong) goes in infinite loop, giving a stack error.
But flashing Sonoff don't clear the script?
Best regards

(continue)
I make a simple 'flow' in node red: a catch-all with debug echo, and 3 commands: blink, toggle, off.
All looks working.
But I don't see the commands I expect in debug window.
To be more explicit I change 2 lines: 53 and 95 (about). I replace remote payload:
publish remote $status_topic $relay_status retained
with
publish remote $status_topic "{Time:" | $timestamp | ",Power:" | $relay_status | "}" retained
and on console only
No echo of remotes commands. For remotes commands I expect a remote echo and a local echo. (?) But this can be a Putty problem.
Maybe I am confused between 'local' and 'remote', but how to send status to mosquitto?
More:
the lines: publish local $status_topic $relay_status retained
looks to me useless. None uses the 'local' status topic, the program uses only 'local' commands.
Best regards.

Hi,
I think this is very useful project for small IoT devices.
I have found a minor issue if a client give NULL password to the broker...
For examble,
mosquitto_sub -h 192.168.4.1 -d -u "user" -P "" -t hello
mosquitto_pub -h 192.168.4.1 -u "user" -P "" -t hello -m message
There are always "MQTT: Out of mem" in the debug log due to the following conditions in mqtt_server.c at line number 532.
if (password != NULL)
clientcon->connect_info.password = (char *)os_zalloc(password_len+1);
if (clientcon->connect_info.password != NULL) { ...
In that case, the value of 'clientcon->connect_info.password' will be always NULL.

typedef void (*MqttDataCallback)(uint32_t *args, const char* topic, uint32_t topic_len, const char *data, uint32_t length);
How to use this "args" in MQTT Broker's DataCallback?
Is it MQTT_ClientCon type?
Can you write a simple example of an Arduino project using the differents functions of the esp_uMQTT_broker ?
How do I add a interrupt to GPIO 0
This seems not to work (derived from user_basic/user_main.c):
#include "user_interface.h"
#include "mqtt/mqtt_server.h"
#include "user_config.h"
#include "easygpio.h"
static void sonoffBtnInterrupt(void* arg) {
uint8_t value = easygpio_inputGet(13);
easygpio_outputSet(13, !value);
}
int interruptOne = 42;
void ICACHE_FLASH_ATTR user_init() {
struct station_config stationConf;
// Initialize the UART
uart_div_modify(0, UART_CLK_FREQ / 115200);
os_printf("\r\n\r\nMQTT Broker starting\r\n");
// Setup STA
...
// Allow larger number of TCP (=MQTT) clients
...
easygpio_pinMode(13, EASYGPIO_PULLUP, EASYGPIO_OUTPUT);
easygpio_outputSet(13, 0); // turn on
//easygpio_pinMode(0, EASYGPIO_PULLUP, EASYGPIO_INPUT);
easygpio_attachInterrupt(0, EASYGPIO_PULLUP, &sonoffBtnInterrupt, &interruptOne);
//Start MQTT broker
MQTT_server_start(MQTT_PORT, MQTT_MAX_SUBSCRIPTIONS, MQTT_MAX_RETAINED_TOPICS);
}
Does anybody experience in your broker always disconnects all clients? All my clients were all disconnected sometimes.
Testing scripts I found a unespected behaviour:
This is accepted:
publish remote $status_topic "{Time:" | $timestamp | ",TOGGLE}" retained
But this not:
publish remote $status_topic | "/user" "{Time:" | $timestamp | ",ON}" retained
With the message:
Error (action command expected) at >>"/user "{Time: | $timestamp | ",ON} retained publish
P.S.
I seen the BNF_: <topic_id> < exp r >, so <topic_id> can't be an expression. OK
One more note:
for a better utilization of 4000 script bytes, maybe it is possible to:

With the problem "wdt reset", I try remake the firmware.
Before "make" command, I changed the value of the "build area" in the Makefile, and wifi AP mode variable( ssid, and password) in "user_config.h" in user directory.
After correction, I applied "make" command at "user" directory but I got error....

How can I solved the problem?
I'm looking to use the ESP as an Access Point and run an MQTT broker on the ESP on a network hosted by the ESP. I can see how to set a host as an external MQTT provider, saying running on my home computer, but how do I set the client on the ESP, as local. And what is the IP to access this through something like Node-Red. I'm trying 192.168.4.1:1883 but no luck.
Help gratefully received.
After flashing ESP, broker startting message displayed.
And then configure loaded.
after a moment, ESP go to 'wdt reset'.
Any help?
Thankyou for PWM!

Hello Martin,
Is it possible to assign static IP address on your firmware? What is the console command to do so?
Hi Martin,
Any chance of having the firmware update OTA in a way similar to the scripts OTA update?
Thanks.

"While the user interface looks similar to my esp_wifi_repeater at https://github.com/martin-ger/esp_wifi_repeater", which leads me to believe that there is a GUI available at http://192.168.4.1 )or somewhere similar) which can be used to do the initial setup.
However when visiting 192.168.4.1 (or http://192.168.4.0) I simply get a timeout.
Am I wrong in my assumption, or am I accessing the UI incorrectly perhaps?
BTW the Telnet interface etc is all working fine.
Thanks.
Hi Martin
I have tested the new firmware.
I have set a static IP address for the ESP in the uplink network (e.g. 192.168.1.250), saved and rebooted the ESP.
After this action, the other ESPs, the PC, a Mob have stopped to connect to the AP.
There was the connection but the DHCP service on the ESP_MQTT has stopped to work on the AP side.
FYI in the former esp_uMQTT_broker there wasn't this issue.
As a temporary solution I have reset the use of DHCP with a dynamic IP address for the ESP in the uplink network.
Now I can again connect the other devises to the AP using DHCP
Thank you for useful Firmware.
After NTP sync has been completed successfully once,
the local time will be published every second under the topic "$SYS/broker/time" in the format "hh:mm:ss".
I want to set publish interval.
set ntp_local_interval1 600
set ntp_local_interval2 3600
set ntp_local_interval3 12:00:00
set ntp_local_interval4 0:00:00
the local time will be published every 10 minute under the topic "$SYS/broker/time1" in the format "hh:mm:ss".
the local time will be published every 60 minute under the topic "$SYS/broker/time2" in the format "hh:mm:ss".
the local time will be published at 12:00:00 under the topic "$SYS/broker/time3" in the format "hh:mm:ss".
the local time will be published at 00:00:00 under the topic "$SYS/broker/time4" in the format "hh:mm:ss".
What a nice project!
my project need PWM control. So how can I enable PWM function?
And where can I get the documents about scripting language used in "script.pir" and "script.sonoff"?
Hope you like my last project: https://github.com/msillano/Sonoff-ebb-and-flow

Hi -
I've been looking into using spi-flash lib to store config info for another project, and have been having trouble figuring out where exactly the 4096 byte sector should be. I looked at your config_flash.c/.h files to see if I could find out what you were using for the 4096 byte block, and it appears you use FLASH_BLOCK_NO * SPI_FLASH_SEC_SIZE or 0xc *4096 = 0xc000. I'm not at all familiar with the ESP memory map (and find what's on the web to be very confusing), but this address seems low to me. so I wanted to check with you if I understood this correctly. I would in fact like to take (most of) your two files and include them in my project as they do exactly what I want. The only issue is I don't fully understand where the config is going, and why.
Thanks for your time.

Hi Martin,
First of all congratulate you for your great job.
I have a request for you. I can't publish or subscribe anything from my cloud broker because my "MQTT client user" is used as the TOKEN to connect to it and it is too short, in fact, it is too short for just 3 characters.
In addition to this, there are some cloud brokers that they need a longer "MQTT_client password" too.
By the way, there are a correction to do in the readme file in your github:
set mqtt_user password: Password for authentication -> set mqtt_password password...
I'd really appreciate you could increase the size of this configuration variables in next firmware update.
Thanks and keep it up!

Hey there ....
i was downloading the prebuild binaries from the firmware folder:
0x00000
0x10000
I'm little bit confused...
Have i flash the 0x10000 to 0x02000 like in the picture or have i flash it to 0x10000?
I tryed out both Variants, with all the settings like the manual Picture from ESP Download Tool, but nothing will happen after flashing....
Also tryed out with Flash Size 8Mb and 32Mb and Baud 15200 and 220400.
What i'm doing wrong?
How to use mqtt-client API such as
function "MQTT_InitConnection(....)" , "MQTT_InitClient(..)" etc..
on ArduinoIDE ?
Is there any example ?
Thank you.
Sorry, i have more problems.
The script.sonoff works well.
But if I add the fallowing code to enable a switch on GPIO 14
% The remote switch
on gpio_interrupt 14 nopullup
do
println "New state GPIO 14: " | $this_gpio
The GPIO 0 (on board button) ceases to work.
But GPIO 14 works.
Strange.
Some limit on Interrupt use?
Best regards.

Hi,
I would be useful to allow internet routing, as your esp_wifi_repeater do (possibly as a bridge, no NAS). Is it a problem to add such a feature?
Thanks

Hi
This looks great but... 8 clients? I think my little IOT setup has about 15 ESP8266s talking to the broker - any chance of increasing that number or porting to the (now much cheaper than a few months ago) ESP32??
Hi,
Is there a limit on the password length for mqtt_password?
I'm trying to add a remote mqtt broker, it always has 1 missing character in the password after set mqtt_password
Hi,
I was trying to upload the firmware to a NodeMCU but have no success seeing the SSID MyAP:
What is the correct LED behavior to indicate a proper upload?
Thank you.
In my script I can subscribe and receive specific events no problem.
But if I try to receive all events first I get script error because of # "Error (number of hexdigits must be multiple of 2) at >># on topic local "#...
If I put # in double or single quotes it accepts the script but no topics are matched and printed to serial_out. Also tried #.
on init
do
subscribe local #
on topic local #
do
serial_out "Received: " | $this_topic | " , " | $this_data
Is there some other trick to subscribe to # ?
Thanks!
Hi, how are you?
After some time dedicated to HW, back to using your wonderful esp_mqtt.
Doing a watering timer, I have some problems with flash variables: when I write a value shorter than the stored one, i get the 2 values mixed, like an overvrite.
Workaround: i add a space to numeric value
fragment (inside an 'on topic'):
setvar $tmp = (json_parse("value",$this_data) * 60000) // value = 1... 180. min: @2 60000... 10800000 ms for timer.
setvar @2 = $tmp // this not works
setvar @2 = $tmp | " " // this works for me (?)
println "Set howlong " | $tmp | " (" | @2 | ")" // only for test
Second problem:
The NTP client implementation do not uses Daylight saving time. So to get the rigth time, I change the TZ.
But this can be done only with a 'config', so not at run time inside an 'on topic'
So it is necessary the use of telnet to port 7777 to change TZ for DST.
Branch: Master
Commit: 6964c0e
Device: Sonoff switch
According to the "Usage" section of the README.md
the default WIFI AP name can be changed by editing file user_config.h
.
But when I change line 9 in user/user_config.h
, it has no effect after flashing the device. I seems like the configurations are stored on some not flashed eeprom. Is this true? How can I overwrite those configurations?
When I change e.g. printf's in file user_main.c
I see changes. So my tool chain and flashing works.
