stat/Sonoff_4CH_R2_lumini_1/RESULT:
{“Command”:“Unknown”}

what am I missing?

Seems like we are using an identical topic config, so here are my (currently fine working) topics.
This is still the v1 mqtt binding, but that should not maky any difference when the topics are the problem.

Odd
Try using a shorter topic
Try also the fallback topic

my mistake: I entered “ON” on the topic line in mqtt.fx
now I both used a shorter topic and entered in the righ place and it works

thanks
