@Wayne-TP I have now installed additional KH100 hub, that is closer to these valves (so the temp sensor and these 2-3 closest vales are connected to the new hub)

It seems they are in sync now, at least couple of times I have checked, the temperature reading was spot on on both valves and the temp sensor. 

It seems that in order to cover my flat (single floor, 140sqm) with perfect signal strength I would need 3 hubs. 

 

The overall temperature stability and ability to maintain a "smooth" temp reading overnight is something that remains an issue anyway. 

I believe its "easier" for these valves to work when there is a higher heating demand, and its easier for them to find the right open state (they dont fully clsoe that often).

 

 

  @Maciej54  Have you relocated this temp sensor too? So both the sensor and the valves are now closer to the hub, right?

  @Wayne-TP Yes, that was the point, now they are in the same room (2 valves, temp sensor and the hub). Btw, valve and temp sensor MUST be on the same hub in order to set it as a designated sensor. I have checked just now, and the issue is still there, you can see one TRV has the correct reading (ok, 0.1 off due to readout delay), but the other one is back on its internal sensor.... (it will get back to external after a while, or I have to make a switch internal / external and it will read right away). 

 

I have also tried the night mode and it makes things even worse:

(these are brand new TRVs and hub - I have moved the old ones to another building).

Its like they only have rough thresholds 0-25-50-75-100% open.  They open to 50%, make one correction to 25%, still too much and back to 0. 

And they cycle like this endlessly :(
