Drayton Wiser iTRV climate entity missing

Hello,
I have HA with the Drayton Wiser integration. Initially I added five iTRVs and three socket/extenders. It all worked great. I’ve now purchase some more iTRVs. I added one and that worked showing the climate element. This one connects through the “mesh”. I added a second.
This has connected directly to the main boiler controller (if that makes any difference). This time no climate control. Appears to be as normal in the Wiser app but not all there in HA.
I removed it from Wiser and it disappeared in HA after a restart. Re added. Same result. This time I also appear to have some phantom aattributes that are possible a legacy of the deleted item.
How do I make this work?
Thanks in advance
Tom
