Hi, I’m on mobile so excuse the brevity.
First, this isn’t an actual binding yet, just an interface via MQTT to Openhab.
You need to have an MQTT broker set up to use it. If you search for Mosquitto and how to install it, that’s the first step. Should take a few minutes, it’s pretty simple and you don’t need to worry about all the extra options, a basic install should work. Also install Mosquitto tools which includes programs mosquitto_pub and mosquitto_sub. This is not crucial, but helps for testing.
Then set up mqtt in openhab.cfg to use your new broker. Info on that is in the Openhab Mqtt binding wiki.
Then you’ll need to install this interface. I think directions are on the github page. Once it is running, you can optionally check if you are receiving input by running mosquitto_sub -v -t “#” which subscribes to all topics on mqtt and displays them. Triggering a passive should show a message.
Then you set up items for each zone in as per my example above, an item for status, and if you want, an item for connect/disconnect.
That should work.
