    I’m looking for some advice as to which smart thermostat I should look at to replace my Nest Thermostat v2 that I currently have.

    I’ve been using my Nest Thermostat and Nest Protects fairly happily since they begun to be sold in the UK about 4-5 years ago. With the only problems being the original Nest Protects removal of the Nest Wave feature (had my v1 Protects replaced with v2 for free) and Nests continued reluctance to add Apple HomeKit support.

    The reluctance by a Nest to add official Apple HomeKit support had been resolved by using HomeBridge with the Nest plugin. I’ve had my Homebridge server setup on a Raspberry Pi3 for the past few years without an issue.

    It’s been announced by Google this week as part of a reorganisation of Nest within Google that the ‘Works with Nest’ program is to close, which gives access to the developer API’s that makes the Nest HomeBridge workaround work and there isn’t going to be a replacement.

    With this being the case I’m looking at replacing my Nest equipment, starting with my Thermostat.

    The options I’m looking are the Tado v3 and the Honeywell T6. I have a Worcester Bosch 38CDi combi boiler.

    I’ve had a look at Tado and I would need to buy both the Thermostat and the Extension kit as I don’t have an existing direct connection between the two. Is it recommended to buy radiator valves at the same time to achieve maximum efficiency?

    Would every room radiator with an existing TRV require one, how does it work with larger rooms my kitchen has two radiators both with TRV’s? What about heated towel rails?

    Does anyone have a Honeywell T6, if so how do you find it?

    I have 3 tados each controlling 3 zones and I’m very happy with them

    I don't know anything about the Tado but I've been using Honeywell thermostats professionally for 20 years. Really they have a firm grip on the non-smart thermostat market, at least here in the US.

    The thing I like about the Honeywell in your case is you and set the cycles per hour and aggressiveness to match the type of heat you have (radiant) and then fine tune it. The purpose of this is to get a balance between comfort and efficiency. Heating, cooling, refrigeration, etc is the most efficiency when its up to its design speed and temps so a longer run cycle is inherently more efficiency. However too long and you can feel the temp swings in the room as it warms up and cools off.

    Plus it has a way to be wired in any crazy configuration you can imagine. Technically it would would be easy for you to combine this thermostat with your AC (if you have it) without a relay since you have a Rc and Rh terminals. And it can use batteries if you don't have a common (neutral) wire from the combi.

    That said I think it was one of the ugliest smart thermostats on the market. A quick glance online and I think the Tado looks much nicer.
