Ok, so far the theory is ok.
It is quite frustrating working with openHAB and all related issues. I am close to throw everything into the garbage bin. I followed the tutorial at this link:
https://community.openhab.org/t/oh3-tasmota-relay-via-mqtt-sonoff-basic-with-optional-dht22/111485
BTW…I have:
- openHAB MQTT broker ONLINE and bridge thing configured (step 1 tutorial);
- tasmotized device MQTT set as required…User…topic and so on, (step 2 & 3 tutorial)
- openHAB configure to connect to the device; (step 4 tutorial)
- openHAB configured to control device (step 5)
- Mosquitto in working as I checked with netstat -an and port 1883 under IP 127.0.0.1 is connected/established;
…nevertheless…the switch DOES not activate the device.
What else can I try/check???
