[SOLVED] Arduino >> openhab. howto handle received payload string to toggle switch state

@ThomDietrich
Hi Thom, This observation was not meant as a critcism. While almost all of the necessary detail is there, what’s lacking in large amounts is simple, complete examples which give these details context for newbies like myself. As a general observation, this feedback applies almost all OpenHab documentation.

Having tried to get a couple of other systems up and running over the past week or two, I have stuck with OpenHab because it was the easiest and quickest to set up, but it’s not perfect, and just because it’s the easiest, doesn’t make it easy.

I’m greatful for all the help I’ve received, although you could look at the active community in two ways - isn’t it great experts and beginner can come together with their passion for OH - or it could be an indicator of areas of improvement of examples that complement the documentation.

In short, the instructions wiki MQTT Binding (v1.11) did not become the main reference for my ongoing implementation of MQQT and OpenHab due lack of clear examples.

What I have been doing is documenting my steps, and will happily share that once I feel it’s repeatable. It will cover off install Openhabian and Mosquitto, making a Backup, connecting an Arduino over WiFi and controlling an LED via mqqt.
