Home Assistant MQTT discovery

[escoand]

I would like to request MQTT discovery feature so that you don't need to add all these sensors by hand. https://www.home-assistant.io/docs/mqtt/discovery/

Don't know if other home automation systems understand this as well or if they have similar interfaces...

@thanksmister This should be the correct payload for all the sensors.

Hello, perhaps I have to say "Thank you!" for the whole Team, The App was exactly what I was looking for.

Regarding this issue: Instead (or together) with the Home Assistant auto discovery I would suggest you take a look at the open "Homie Convention" It is doing the same thing but is device, sensor and control system independent. It is used by openHAB, Node-RED (via contrib node), Home assistant (via a module) and many others.

I maintain the ESPEasy plugins and the Node-RED contrib node and can say this is an elaborate, complete, flexible and cool standard for communication via MQTT - and I love it. Personally I have NO experience in java so I think I`m not able to contribute in this case, sorry.

+1 for this. Wallpanel is an amazing app already, and MQTT discovery would save a lot of Home Assistant restarts while testing new devices.

+1 for implementing this for home assistant.
