I've had a similar hit-and-miss with room stat MT10 RF (battery operated) paired with Worcester Greenstar 25 si Compact Combi. Technical Support at Worcester-Bosch told me the stat has an accuracy rating of +/- 5 deg C which is useless. I've tried turning the room stat to max and relying on TRVs but I reckon TRVs also have a similar accuracy range. If I throw money at the problem what do people recommend?

You said, the boiler is switched off over night. Do you mean you kill the power to the boiker over night?
Depending how stat has been wired, turning power off can cause stat to loose communication with receiver. You don’t need to kill the power over night. If you do loose power you might have to press reset button on stat.
