Publishing of messages not working #57

Closed mountaindude closed 8 years ago

mountaindude commented 8 years ago

I don't Homie responding to ANY MQTT messages, which could be cause by

  1. Incorrect MQTT topic being used by me. For the demo on https://github.com/marvinroger/homie-esp8266/blob/master/docs/2.-Getting-started.md, I understand the topic should be devices/003/light/on and the message should be true (assuming the device ID was set to 003 in the config).
  2. Some issue in Homie, preventing it from getting the MQTT messages
  3. Probably lots of other reasons too.

Also, after reporting the system messages to MQTT, the device sends a couple of "devices/003/$signal" messages, then goes offline with a "/devices/003/$online" = false message..

Would be good to rule out option 1. Can someone confirm that topic and message is correct, for the demo code referenced?

Using an ESP201 Sweet peas ESP8266 device, with latest PlatformIO (2.8.6) and Homie (1.3.0).

You should use topic devices/003/light/on/set => true/false

marvinroger commented 8 years ago

Yes, to receive messages you need to send them on devices/003/light/on/set..

The "/devices/003/$online" = false is not normal, it means the device is disconnected from the broker... I'll investigate.

marvinroger commented 8 years ago

By the way, what is your MQTT broker?

mountaindude commented 8 years ago

@dholmen, ah that can explain it. Will test that topic. I read the docs so many times... but missed that final "set"

@marvinroger: Mosquitto 1.4.2-4 running on a Synology NAS.

@mountaindude read https://github.com/marvinroger/homie :)

@marvinroger: Promise - I did read that (excellent) page a ton of times, just that it was 1.30 am in the morning... should have known better. lol

mountaindude commented 8 years ago

Btw, the issue with the device going offline could be due to the way the serial port works on this particular ESP8266 unit. Will try powering it from just a cell phone charger rather than a computer USB port.

marvinroger commented 8 years ago

@mountaindude I can't reproduce this behavior... Was it a power issue?
