Cannot subscribe to topic - LightOnOff not working

[valentinvieriu]

Hi, I'm trying to implement something very similar to LightOnOff example. I've tried first with the LightOnOff example out of the box, with the version 1.5 of homie-esp8266.

I've tried your advice from #119 and still cannot make it work. My deviceid is esp01. I've loaded the example file and then hitting this endpoint with a MQTT client devices/esp01/light/on/set and I'm getting Node light not registered

Any help is appreciated

Hi!

Can you please paste the output of the Serial monitor on boot? (showing the configuration)

[valentinvieriu]

Sure, Here it is.

Please let me know if there is anything I can provide. The error message apears only when I send the request to devices/esp01/light/on/set from another MQTT client. Pushing works very well. I can send data from the ESP to MQTT. I've tried already with DHT 22 sensor.

Thank you for the assistance!

So the device subscribe to a wildcard like subscription devices/esp01/+/+/set

Hope it helps

Use the examples that are bundled with your release. v1.5.0 needs manual registering of the nodes, whereas this is automatic in the in-development v2.0.0, so current examples in the repo do not work with the latest release. :)

[valentinvieriu]

👍 thank you. You have no idea how much time I've spent yesterday trying to figure this out. Used the 1.5 example and it worked. As I've just started building this project ( I want to install network of sensors in all our meeting rooms at work ), would you suggest to use the 1.5 version, or should I already start with the 2.0?

Again, thank you for the quick reply and support.

[marvinroger]

You're welcome!

The v1.5 is pretty stable, and the v2.0 is far from finished. I don't know when I will be able mark it as stable, but it won't be that soon, so stick with v1.5 for the moment.
