hi@all
1st: i've more then 2 dozen shellies: H&T, buttons, bulbs, plugs, motion, ect.
all are connected to the same mqtt broker with username+password and a custom mqtt prefix
the mqtt broker is an eclipse mosquitto ver. 2.0.11 running on debian buster
so trust me, i'm a bit experienced in it
No chance at all to get the TRV communicating with it!
Strangely enough, the TRV is sending data to a mosquitto ver 1.5.7 w/o username+password
i've to say i was not expecting a green banana because all others shellies are working well with mqtt
p.s.
yes, latest fw and factory restet also done
