Eve Adds Thread Support to HomeKit-Enabled Thermo Smart Radiator Valve

€70 for a thermostat? One?! I have around 12-15 radiators around the house, give or take. A thousand euros for what? A fancy app?

A thousand euros to be able to control each radiator independently. It's way more energy efficient to heat only the rooms that you need and it's also nicer comfort wise to be able to have digitally controlled thermostats in each room. Yes you can balance the temperature dial on regular thermostats but really you need to do that throughout the year as the thermal qualities of your rooms change.

It might be time for me to switch to a new non Nest setup and use these Eve thermostats. I currently have four Nest thermostats controlling three zoned rooms and one for the rest of the radiator system but it'd be really nice to be able to control the radiators seperately in that last circuit. I've always been hoping Nest would add radiator valves or at least play ball better with Apple devices but it's been so long now. I bought into them originally because they were set up by ex Apple devs and they're still the nicest looking thermostats but it's getting ridiculous.

I have a house with 1 centralised thermostat in the living room. Anybody here knows how to deal with this if I want to switch to smart radiator valves? Leave the thermostat always on and let the smart smart radiator valves control everything? Assuming the heater will be smart enough to turn off when no heat is required? Or is a (smart) thermostat still required?

ideally you need something to tell the boiler to start once a smart rad valve (trv) demands heat.

basic wired room stats are on / off (you can usually hear them click as the relay completes the circuit). A smart room stat that can talk to the trv’s can do that.

effectively in an ideal world you need an integrated system with trv’s and a boiler controller.

tado, hive, Honeywell, netatmo and many others can do that.
if you have an ebus compatible boiler it’ll enable more granular control of your heating Including weather compensation which basically tells the boiler to use lower power settings as less rad heat is needed when outside temp isn’t too far off the desired internal temp.

only some smart stats will modulate via ebus, tado with Vaillent requires an older wiring centre plus tado need to make a change on your account to support it.

it’s all hacky.

vaillant ambisense would likely work best if you could find it and an installer to fit it.

There are lots of reviews ('https://www.theheatinghub.co.uk/smart-radiator-valves-product-and-compatibility-guide')

if you have a basic on/off stat then it might be worth the upgrade,

if you have a modulating controller/ stat then just put that in your coldest room and adjust your existing basic trv’s to a comfortable temp, they will shut off when ideal temp reached and the stat will tell the boiler to fire when the coldest room wants heat.

lastly, most heating systems need at least 1 rad with no tr, that should be your coldest room that you put the stat in.

There is normal "smart" thermostats with built-in calendar and program. I found it is already covered 95% of my needs. So I bought 6 for 50 bucks in total. Now I only need touch them 2x every year: set it on in Sep and set it off in Apr.

I've got Hive heating so considering their thermostats... will have to cost them up.

As an aside, that's a pretty terrible publicity shot for that valve.... it looks huge and sticks out really far. Begging to be bumped into. Not a good advert and would certainly put me off purchasing.

Is it software update for existing TRV’s or a new hardware update they are talking about?

sounds like new hardware but update is vague especially in this context.

Available through software update for 4th generation models released last year (product number: 10EBP1701 / part number: 20EBP1701)
