The recently launched DT4R thermostat (YT42WRFT20) is not currently supported and reports "device type 22 not known to have signature: 0002FF1F00FFFFFFFF".

Extract from the log file below.

Oddly. this DT4R thermostat worked perfectly on a different Evohome system running the same version. Device ID 22:033088. I gather the "signature" varies by system and therefore the behaviour is different?

Tested working on v.31.3 and the DT4R works as expected. I will close issue.
