We’ve got smart TRVs in pretty much every room with different profiles for each. In general we set one of 3 different temperatures depending on anticipated room usage for any given time of day/week.
Rooms we don’t expect to use (spare bedrooms etc) are set to 16 with the door closed just to maintain some temperature
Rooms we expect to be in and out of (bathroom, kitchen) tend to be set to 18
Rooms that we are spending prolonged periods in are generally at 20.
Also bear in mind that with these temperatures being measured at the TRV the proximity to the radiators will mean they are probably higher than you’d see on a room stat.
