First of all, COOL!
The video was very helpful and up until the point with the integration into Home Assistant, I was confident I could do it myself.
Now I’m obviously looking at the integration into Openhab, but I suspect it’s quite similar here, you have to add a thing via MQTT, I’ve already found an old post here: https://community.openhab.org/t/configuring-openhab-for-tasmota-things/100383/2
I have several possible uses for it, firstly in my grill kitchen so that I know when the gas bottle is empty.
Secondly, I have a water softener which needs to be filled with salt.
I think I need to get to work on implementing this soon.
