Hello, I'm planning to replace my wall thermostat with a new one, I was looking at the Hive but not sure if it is compatible with the current wiring. See the photos below of my current Salus 300. Any hints appreciated, thanks

As far as I am aware there is only one wireless thermostat that does not need a mains supply to the base unit, and that is Nest e.

However there is no reason the base should not be at the boiler where there is a mains supply.

There are two types of wall thermostat, on/off and up/down, the latter can't be used will all boilers, so the Hive system is designed to allow the boilers own system to work well, but needs at least some linked TRV heads to work well.

The Nest does not link to TRV heads, so although does not need 230 volt power for the e version, and some great control lack of TRV linking makes them rather poor.

Thanks for your reply.
I found those stats that requires 2 wiring only:
- Hive SLT5
- Tado kit
- Nest e
