Hello!

when trying to install the Tasmota integration on HA i am getting following error message:
Unable to set up dependencies of tasmota. Setup failed for dependencies: mqtt

following stack trace:

Version used: 2021.2.3 with Home Assistant OS

Mosquitto is already installed and apparantly properly operational:

1613612416: New connection from 192.168.1.226 on port 1883.
[INFO] found tasmota-mqtt on Home Assistant
1613612416: New client connected from 192.168.1.226 as Büro (p2, c1, k30, u'tasmota-mqtt').

When trying to install the Tasmota integration the loading screen just pops up for a fraction of a second and then vanishes. No clue what to do anymore…

Thanks!

Did you complete configuring the mqtt integration after installing mosquito addon? If you haven’t please complete the mqtt integration and restart

I did

Nevermind, after the 20th reboot or something it auto-recognized the tasmota devices…
