Tasmota Integration: auto discovery not working

Hardware
1

Hi,

I have 3 D1mini. All of them send mqtt-data to my mosquito in HA. But only two have been added into HA. The third one ist not available as a sensor.

I read somewhere that auto discovery can be switched on/off in Tasmota? setoption19 is already set to “0”.

Details on the D1mini: → tasmota-display.bin

There is an AM2301 Sensor (temp/humidity) and a SSD1306 display connected to the D1mini.

mqtt data is comming in.

This d1mini is missing in the tasmota integration:

Any help is very much appreciated.

(my question seems to be related to I accidentally deleted the wrong device a “D1Mini” from my Integrations–>MQTT broker. And I would like to reintegrate it)

Well, I tried to do an over the air update of the mentioned D1mini - but i failed. After a rebooting the D1mini over its web-interface, the entities are now available in HA…

I am happy, it is working now, but it would be nice, if someone could explain the reasons behind this and how to debug it in the future.
