Have a play and let me know how you get on. Until my PR gets merged with the main Domoticz code base, you'll get to grab the code from my branch at
https://github.com/brucemiranda/domoticz
I confirm that the new code you pushed late 2019 in the main dev branch of Domoticz is working fine.
It shows proper values on my system (based on a Perfinox 4100 + HGI80 + OT Bridge).
I'll need to wait until your code is streamlined into the dev branch of Domoticz, I would like to avoid wrecking up my current Domoticz config by switching to your dev branch.
If I may comment, having a unit displayed for the values with a unit would be great. I'm not sure the official OpenTherm specs units that are supposed to be used.
