Hi,
Below is the things config that works for me, I only use cli no paper ui, if this helps.
Bridge mqtt:broker:mosquitto "Mosquitto" [ host="0.0.0.0", secure=false, username="openhab", password="Xxxxxxx", clientID="openHAB2" ]
{
Thing topic StudyShelly1 "Shelly1" @ "Study" {
Channels:
Type switch : power "Power" [ stateTopic="shellies/shelly1-056DD7/relay/0", on="on", off="off", commandTopic="shellies/shelly1-056DD7/relay/0/command", on="on", off="off" ]
}
}
And my single item
Switch MQTT_Test2 "Study Shelly1" <switch> (SF_Study) [ "Lighting" ] { channel="mqtt:topic:mosquitto:StudyShelly1:power" }
Done from my phone so hopefully copied ok.
