Temperature Accuracy
Yesterday I installed a wired Smart Thermostat and its working "fine". I initially set the temperature at 20 and the thermostat never went over 20.1. Tonight I felt colder and increased the temp to 21. Since then the thermostat has been pushing the temp as high as 21.6. Is this discrepancy "normal"? As I am using the App or thermostat itself to find out the temperature I don't see offsetting the temperature will have any real effect.
Additionally, I have a combi-boiler and noticed at 20 the boiler often came on for short periods which were so short the radiators only ever got warm rather than hot (boiler water temp set to 62).
Whilst I understand algorithms and learning are involved I cannot understand the inaccuracy in temp instigated by a 1 degree increase in temperature setting.
BTW there are no TRV's just the one wired room stat.

It's typical for the room temperature to overshoot when Tado is requesting heat to reach the target temperature. Once the target temperature is attained and Tado is simply maintaining the temperature it's normal for Tado to turn the boiler on for short periods. It's operating as a TPI thermostat and you can see the level of demand in the Care & Protect menu. So at 33% Tado will be switching the boiler on for 20 minutes in each hour. If you find the boiler on time to be too short you can ask customer support to adjust the minimum on time. The radiators being warm and not scorching hot is perfectly normal, providing the room temperature is correct.
