Linking Nest and Energenie MiHome what happens?

I expected with Nest set to 17°C at 8 am that the target temperature for the TRV would also change to 17°C, or at 4:30 pm when the TRV changes to 19°C that Nest would also change, but it seems they have not synchronized in any way, I see no change in what the devices report after being linked to before they were linked.

It seems Energenie Mihome is no longer supported by Nest, I did manage to link them, but it was intermittent, when I altered the temperature on Nest with phone the TRV followed, but when turning the dial on Nest or when a scheduled change in temperature happened it did not seem to follow. Also there is no option to set an off set, and the TRV is normally cooler than the wall thermostat, so the TRV needs to be set cooler.

So the TRV are not linked any more, but the schedule are set so they complement each other, this means there was no real need to use the expensive Energenie MiHome TRV, any cheap electronic programmable TRV head would have worked just as well.
