This should be simple but I can’t seem to get it to work.
I try to send messages from an Arduino + ESP8266 (NodeMcu) to set a switch on the OpenHab server.
The Arduino connects to my OpenHab server and publishes MQTT messages.
I see the messages from the Arduino with mosquitto_sub on the OpenHab server like:
I also see all state changes of my OpenHab items with the mosquitto_sub command.
So it looks like all is installed as it should be, however, I can’t seem to find how to use this published topics to the OpenHab server to set a state on the sitemap.
