I have a Honeywell CM921 Thermostat. I would like to install hive. Can anyone please help in advising me if the wires are compatable with hive.

Here is my current setup.

Brown wire to hive L
Blue to hive N
The wire in B goes to hive 3

Remove the link wire from L to A you don't need it.
The yellow and green shouldn't be used as a live so at least sleeve it brown.

Surely you won't be putting your Hive centre where the thermostat is. The Hive needs to go near the wiring centre.

The Hive stat would go near where the old stat is/was. Or in another/ better location.
And (as above) using the earth conductor as the switched live is a big NO. That's the sign of a cowboy.
So more electrical wiring may need to be sorted.
