OK, I have the daemon installed and running, and the integration.
HA recognised my TKB switches OK, but only partially recognised the Danfoss radiator valves. It recognised the device and the battery state entity, but not the set points and other entities. Looking at log.json, there’s plenty of traffic about full discovery of the rads, so I’m guessing that there’s something missing in the addon.
Luckily, I don’t need the rads right now - I hope 
- so I’ll stick with it.
I’ll dig deeper and raise an issue where appropriate.
EDIT: I see from github that the climate elements were only added to the codebase a couple of days ago. I’ll leave well alone for now as I’m running 110 rather than dev code.
