Home Assistant Discovery for Zigbee Sensors (only Temperature + Humidity)

[fleinze]

Something that is sadly still missing is a Home Assistant integration for Tasmota Zigbee gateways.
I wanted to give it a try. The integration on the HA-side is quite complex and changing it is beyond my capabilities. This is why I tried to fix my gateway to become HA compatible.
First of all to get the SENSOR-topic payload compatible with HA I hat to use setoption83 1 and setoption100 1
Second HA expects all sensors to be listed in the discovery topic. So I wrote a short berry script:

#needs the following command to make the payload compatible with home assistant
#backlog setoption83 1; setoption100 1
#only works for temperature and humidity sensors
import zigbee
import json
import string
import mqtt
var disco_pl = {'sn':{'Time':tasmota.time_str(tasmota.rtc()['local']),'TempUnit':'C'},'ver':1}
for device: zigbee
  var info = device.info()
  var ins = {}
  for i: 0..info.size()-1
    if info[i].key == 'Temperature'  
      ins.insert('Temperature',info[i].val)
    end
    if info[i].key == 'Humidity'
      ins.insert('Humidity',info[i].val)
    end
  end
  if ins.size() > 0
     disco_pl['sn'].insert(device.name,ins)
  end
end
var mac = string.tr(tasmota.wifi()['mac'],':','')
mqtt.publish(f'tasmota/discovery/{mac}/sensors', json.dump(disco_pl),1)

This script creates a new discovery "sensors" topic and overwrites whatever tasmota published before. With this all temperature and humidity sensors become available in Home Assistant.

It is very quick and dirty and has many limitations. It only supports temperature and humidity sensors, although this could be quickly expanded to other sensor types.
There is also no support for any kind of switching device.

What do you think? Any ideas to make this better?

What you talk about has a lot of parallels with a recently created Berry project on Github:

Thanks, I will take a look at this project!
