Hi, I have a large number of Tapo/Kasa products already. I now want to equip all of the radiators in my large house (20) with smart TRVs. As a test I have purchased enough for one large room that has 4 radiators.

So my test setup is as follows - 4 x KE100s, a KH100 hub, and a TP315 thermometer. 

The setup went very smoothly. I use the TP315 to control the KE100s that I have put in a group. I used Smart Control in the app to set up a heating schedule. Everything turned on perfectly as expected but I have come across one issue.

I set up a target temperature (of the TP315) in the app of 22c. However, well before reaching the target temperature the KE100s start to close down and then cool down. As a result, the room never achieves the set target temperature of 22c. I can understand the logic of the KE100s starting to close near to the target room temperature so as to avoid a large 'overshoot' in room temperature but these valves are shutting down way too soon.

One option is that I could set a higher target temperature, say 23c, and then when the KE100s 'switch off early' I can achieve my target room temperature, but this just seems a 'bodge' to get around the devices not working properly.

Is there any way of tweaking the valves as, as it is, these do not really meet my needs. What about somehow using Smart Actions rather than Smart Control to turn the KE100s on/off based on the actual room temperature, thereby circumventing the early valve closing?
