Just started playing with evohome-listener, and I've got a few questions. To start with, I'm picking up a device type 12. But this is not defined anywhere. Any idea what this might be?

The other question is what is zone 252? I'm seeing entries like this:

2020-10-19 18:23:23 |1/073| ZONE_HEAT_DEMAND | I | CONTROLLER -> BROADCAST MESSAGE | 43.0% [Zone 252]

I'm guessing it is the boiler relay, but I've defined that as Zone 99 in devices.json (or is it hardcoded to 252)?

Great piece of software btw.
