PI3b on Openhabian2.2
I am trying to understand how to use Sonoff/Tasmota switches with OH2.
What do I want to do:
I do have a running OH2 with Z-Wave+ and FS20 CUL. Just did now successfully my first steps with great support here in the forum.
Now I would like to extend the OH with some Sonoff/Tasmota switches.
What I need:
I am using a classic PIR with a closer relay to switch the sonoff switch for a second.
(Therefore the PIR relay will close PIN 4 and 5 on my Sonoff)
This Sonoff switch signal I want to read with OH2 in order to switch a Z-Wave switch via OH2.
What I don´t understand:
Is it enough to just install the MQTT Binding or do I need to install JSON or something else?
I am not a developer and therefore I don´really understand this MQTT and
even less what is JSON and how to read such a signal from the sonoff via MQTT.
Who can help? Yes, I was reading in the forum, but to be honest this is a real confusing
topic for me.
Thanks a lot
