I have the same settings, and no devices are found.
Setup: RPi3, latest beta Domoticz, done the setoption19 1 thingy, MQTT up and running.
MQTT Host 192.168.0.124
MQTT Port 1883
MQTT Client & Fallback Topic DVES_AF76EE
MQTT Topic sonoff35 (every Sonoff has it's own Topic)
MQTT Group Topic sonoffs
MQTT Full Topic cmnd/sonoff35/
Full topic: %prefix%/%topic%/
MQTT Server address:localhost
Discovery topic: sonoffs
Ignored device topics (comma separated): tasmota/sonoff
What is wrong with this setup?
I also have this error message in the log:
2018-06-03 11:30:25.656 (MQTT discovery) Warning: could not load plugin options '' as JSON object
What could this mean ? How can I solve this ?
RPi3 + RFXCOM rfxtrx433E + Xiaomi Gateway + Philips HUE Lights + Nefit Easy + Dashticz v2 + Domoticz latest Beta
