I bought a house where the previous owner left a RasPi with Domoticz, an OTGW, Hybrid Heat Pump (or what you call it?) and ofcourse the CV kettle.
The OTGW is setup in the Domoticz, and I've seen it in my Device list for a while now but never really understood what all the different devices and acronyms mean.
Below you can find the devices that exist in my Domoticz environment, I don't expect anyone to go through it all with/for me, even though I would appreciate that. I'm basicly just looking for documentation so I can understand how this works. And how the OTGW works at all. I looked on their website https://otgw.tclcode.com/index.html but didn't get any wiser.
The OTGW I have here is a USB version with version 4.2.5 (at least that's what Domoticz tells me!

Hope you guys can help me out!

Thanks in advance!
