Where can I find the best module for my buva box?
I see 3 versions, with comments not tested or other remarks, So I'm not sure which one is the best for me and can be bought in the Netherlands.

or are there plans to sell these sets, so we can also contribute in a financial way to this project?

I am using a wemos d1 mini esp32, which should work without issues since it's just an esp32.
but i keep getting "nRF905: config failed" errors.

I even tried setting the gpio manually and moved the SPI connect to the official SPI pins, but no success.

Tripple checked the connections.

#define PIN_AM			32					// nRF905 AM pin (Address Match)
#define PIN_CD			33					// nRF905 CD pin (Carrier detect)
#define PIN_CE			27					// nRF905 CS pin (Enable pin)
#define PIN_DR			35					// nRF905 DR pin (Data Ready)
#define PIN_PWR			26					// nRF905 PWR pin (Power mode pin)
#define PIN_TXEN		25		  		// nRF905 TX_EN pin (Transmit enable pin)
#define SPI_MOSI		23	  			// nRF905 CSN pin (SPI slave select pin)
#define SPI_MISO		19  			  // nRF905 CSN pin (SPI slave select pin)
#define SPI_CLK			18				// nRF905 CSN pin (SPI slave select pin)
#define SPI_CS			05          // nRF905 CSN pin (SPI slave select pin)

any ideas?

In the latest release of HA (Home Assistant) they moved fan speeds out in favor of a percentage, see https://www.home-assistant.io/blog/#fan-speeds-100

I would like to ask for a new feature, an API endpoint that can use this, including an optional timer parameter:

/api/v2/fan/setpercentage.json

Set the fan speed by a percentage of your fan device.

Example:

http://192.168.x.y/api/v2/fan/setpercentage.json?percentage=50

Since upgrading to v1, my NodeMCU ESP8266 crashes after running the API for a few hours.
The blue LED also turns off.

I can remove power and restore it, then the NodeMCU boots and the API works again for a few hours.

First of all: thanks for your great work! I ran into an issue when enabling HTTPS. When I set #define NRF905API_HTTPS from 0 to 1, I get the following error message:

<path>\nRF905-API\src\nRF905API\nRF905API.ino: In function 'void setup()':

nRF905API:194:54: error: 'serverCert' was not declared in this scope

  server.getServer().setRSACert(new BearSSL::X509List(serverCert), new BearSSL::PrivateKey(serverKey));

                                                      ^

nRF905API:194:91: error: 'serverKey' was not declared in this scope

                                                                                         ^
exit status 1
'serverCert' was not declared in this scope

When I change NRF905API_HTTPS back to 1, it compiles successfully.

I learnt a lot from this project, but had a lot of problems around reception and reliability with the RF chip. I tried for a long time to find a more reliable version, but failed.

I solved the problem by connecting a raspberry pi to an Adafruit digital potentiometer and the directly to the Zehnder fan board. This works much more reliably than the RF connection. I then communicate with the pi over Wifi. I use python to set the fan speed. I've also bought some very inexpensive humidity & temp sensors that send the data to the python script, so I can turn the fan on automatically when shower goes on.

If people are interested, I'm happy to share the code/design...

Hi,

Firstly, thank you for writing this api, I'm very much looking forward to using it for controlling my Zehnder Comfofan S.

I have setup and wired the chip successfully (I believe) and uploaded the software. My setup is:

RF Module: https://www.amazon.nl/gp/product/B08GLQF3TK/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
MicroController: https://www.amazon.nl/gp/product/B074Q2WM1Y/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

The Serial Monitor log is below [1], which I think in general looks good, I can access my chip from the network. I did have an issue initially connecting to the wifi but that was just because reception was bad in the loft.

When I try and use the api for example by entering this into the webpage,

http://192.168.178.225/api/v2/fan/setspeed.json?speed=high

I get this response.

{"result":"no_reply","error":"Command sent but no acknowledge was received","rxdata":[]}

I have recorded the wav's using rtl_fm, which I can send if useful. It is definitely transmitting but looks weeker than the Zender RF button I have.

Are there any other steps I can use to debug the issue? Any help is much appreciated.

Chris

I have connected the setup with my ComfoFan Silent - P. (the perilex version)
However, even at maximum the speed percentage is 61. See below.

Is this a weirdness in my fan setup or is this a software thing?

Hi,

I had difficulties running the setup and changing values (like username and pass) in the configwizard. It seemed that changing default values was not possible.
Reason:
There are multiple places in configwizard.cpp where strncopy uses sizeof(CONST). In this case too little bytes are copied.
Examples:

strncpy(config.language, server.arg("language").c_str(), sizeof(MAX_LANGUAGE));
strncpy(config.http_username, server.arg("http_username").c_str(), sizeof(MAX_HTTP_USERNAME));
strncpy(config.http_password, server.arg("http_password").c_str(), sizeof(MAX_HTTP_PASSWORD));
strncpy(config.wifi_hostname, server.arg("hostname").c_str(), sizeof(MAX_WIFI_HOSTNAME));
etc...

please use:
strncpy(config.language, server.arg("language").c_str(), MAX_LANGUAGE);
etc..

And all will work fine!

Note also that strncpy will not zero-terminate the string which also might lead to unpredicted results in case one uses a large string. Actually you should zero terminate it by: config.language[MAX_LANGUAGE-1] = '\0'
or create a function:
void safestrcpy(char dst, const char* src, int max_length)
{
strncpy(dst, src, max_length);
dst[max_length-1] = '\0';
}

Hi,

First of all: many thanks for this bloody brilliant piece of work. I had the antenna's laying around for 3 years already but I was lacking all knowledge you luckally posses.

I notice this on the on other forums as well, but since i don't have a logging there I took the freedom of reporting the bug here.

I have a Zehnder Co2 sensor in the living room, which overrules the calls to setspeed and setvoltage. The ventilator responds but a few seconds later it will go back to auto. Only way to keep the ventilator running is using the parameters.

Would be happy to use the setvoltage with a slider bar in Home Assistant.

Hi, I am using Lolin32 Lite with nrf905 and I seem to be unable to pair with ComfoAir E300 RF:

Not sure whether this is related to NRF905 issue, but it looks like it can "receive" some data (based on the second output).

The setup UI is great as it improves user experience a lot. I checked my previous config files to see what I've configured manually.

Already covered:

• Hostname
• HTTP Username and Password
• WiFi SSID and Password

Not covered (yet?)

• Enable HTTPS
• Disable IPv6
• OTA Password

Would it be possible to integrate these as well? Especially the HTTPS / IPv6 config options as OTA is disabled by default.

Thanks!

Is this menu to authenticate with the NRF905 or is it for configuring the authentication? I think it's the latter. I also wonder if the setup screen should be accessible after the NRF905 is out of it's initial setup. Especially the authentication part of the setup. Otherwise the username and password can be easily changed by someone on the network.

Hi,

I have a BUVA BoxStream RF+ I would like to control using your API. For this project I bought off AliExpress a V2 Nodemcu-CP2102 (ESP8266 ESP-12E) and Wavgat NRF905. Yes, I know these aren't the exact types you advise, but I took my chances due to the cost difference. Perhaps the hardware is the reason for my trouble, please let me know if that is the case.

I succeeded following the steps for building the hardware and programming the nRF905 API software to the NodeMCU. The configuration wizard was successful up until the fan discovery wizard. I unplugged the fan unit and plugged it back in, after which the wizard should say "Your fan is successfully configured". However, I got the message "Warning: hardware error while configuring the nRF90".

And indeed, after rebooting the NodeMCU, it connects to my configured WiFi, but the configuration wizard starts again when I open the page.

Please let me know if there is something I can change or do or try, or if I should just buy other boards. :)

When I use the new api/test/fan/querydevice.json query, it returns a 200 status code even when the API could not receive a reply from the Zehnder system:

I think that in this case it might be better to return a different status code. Maybe 504 is a better way of handling this error.

It would also make it much easier for e.g. Home Assistant to understand that something went wrong and that the previous state needs to be kept until a successful call can be made.

Thanks!

Dear Eelco,
having build a ESP32+nRF905 setup I have loaded your API but got stuck on the presets for Zender/BUVA. There is a manual option but I don't know it that is suitable for connecting an Itho system.
Is there a way to use your efforts and the manual mode with the correct values? Or is your API not compatible with the rf-codes for Itho? It would be very beneficial if Itho systems would also be added.

Many thanks in advance.
Regards, Wolly

Ik merk dat ik bij mij vaak twee of drie keer een call moet aftrappen voordat er daadwerkelijk iets gebeurt. Hebben jullie dat ook? Wellicht komt dit doordat het ESP-bordje in de kast 2 muren verderop ligt?

Misschien een idee om de code aan te passen zodat hij een retry doet op het moment dat er geen feedback komt van de Zehnder ComfoFan?

Fantastisch werk! Nu maar hopen dat ik het snel aan de praat krijg thuis :).

Ik ben niet helemaal thuis in knutselprojecten en ben onlangs begonnen met het aansturen van onze Bellfires gashaard met een ESP8266 die geconfigureerd is met ESPHome en daardoor enthousiast geraakt.

Nu probeer ik onze Buva aan te sturen met de volgende componenten:

• nRF905 module
• DOIT ESP32 devkit v1 (30 pins)

Ik probeer de volgende stappen uit te voeren maar kom helaas niet verder dan stap 6.

Ik heb de DOIT ESP32 DEVKIT V1 geslecteerd en de baud rate op 115200 gezet.
Ook heb ik de flash frequency op 80Mhz staan, maar dat was default voor het bordje.

Verder heb ik de bedrading (dupont) 2x nagelopen en zie daar ook geen bijzonderheden.

Iemand een idee in welke richting ik moet zoeken?

I bought a nodemcu and de nfr followed the steps but got errors and don't know how to resolve. What's wrong? What do I miss?

I see also a folder on this github: homeassistant. is that a option to flash it with esphome or something?

Hello,

how can i find the correct payload with a CO2 sensor. I changed the Tx adress to the correct one, but the payload are not working correct. When 1 sent 10 minutes max speed, it won't stop after 10 minutes.
