I'm playing around with the D1 mini. Tried Reed Contacts and a PIR. Anything is working fine but I cannot get any update to Domoticz.
Im using the generic 18 module and set Pin D2 to Switch1. Configured MQTT and Domoticz like the other 4 Tasmota Devices that I have. Checked it the 5th time...
In Domoticz I have created a Dummy Switch
I see every change in the Tasmota Log, but not in the Domoticz Log. Also the Dummy Switch isn't changing.
If I change the Tasmota module to something different, e.
G. Blitzwolf Plug, then anything works like it should.
Changing back and it is not working anymore.
I wonder if someone I'd using this setup and can say that it at least should work. Personally I'm thinking, that this could be an issue in Tasmota.
What do you think?

Tasmota 6.7.1
Domoticz 4.11551 running on RPi
