Best Wifi enabled thermostat

Hive 2 and Nest 2 thermostats are reduced to £150 on Amazon (both without installation) at the moment. Leaning towards the Hive...

V3 of nest just launched in the UK. Brings hot water control.

I really want to jump to nest from tado as I'm a huge google geek, but I just can't see what it brings over tado. IT doesn't even have proper geolocation

It doesn't? https://nest.com/support/article/How-do-Google-voi...

Help...help please! ....baffled by all this techo stuff.

We have a holiday cottage we use every 3 to 4 weeks. I just need something which will turn up the room stat a few hours before we arrive. No need to turn it on as we leave the boiler running, with the stat turned down low to about 15c. It's also an oil boiler, so BG will not install their Hive.

Is there something I can replace just the room stat with, without having to mess about with wiring from the boiler into the receiver?

Thanks

I think I'm going down the Honeywell Evohome route myself - no other system I can see allows me to zone my heating without lots more expensive plumbing and confusing electronics.

Evohome here, does hotwater and 12 zones (max you can get). Its great, I can have the bedrooms off all day, only coming on before we go to bed, the lounge only on in the evening, kitchen on in the morning for when I get up 2 hours before everyone else, then off for the day until the kids get home, when their bedrooms get turned on.

If I decide to work from home, kitchen and office on, everywhere else off. total flexibility and controlled from my phone (as long as I have signal).

If its now got IFTTTTT, then I'll be a coding shortly.

Yes, Tado would work perfectly for you - if you have a wired thermostat then just replace it with Tado, but you will need internet connection.

Wonderful! Yes, we do have internet there. Thanks

No need to be with British Gas to install Hive. In fact I installed it myself a few days ago, liking it so far, but you can order it with "professional installation"

that sounds pretty good! what is needed for that kind of setup? i assume each bedroom has a evohome TRV or thermostat on the wall that the main Evohome stat controls?

Each radiator gets its own Evohome radio-controlled TRV, which all report back to the main controller, which can live anywhere.

You can link radiators together to create a Zone. So I have two radiators in the bathroom linked together called Bathroom. But I have seven radiators across four rooms all linked together and called Open Plan, as most of my ground floor is one large open plan room (orangery, lounge, hall, kitchen). You decide which TRV of those seven is the 'master' for the zone, and the others are slaved from it. I heat that area during the day and the bedrooms for half an hour before bedtime. The rest of the time the bedrooms are not heated at all.

How do Evohome price - is it a starter kit and then add TRV's or do you buy the main unit and then build up or?????

John Lewis had a reasonable deal on the v2 Nest on Friday. I've got an elderly combi boiler than uses a simple two wire thermostat:



I pulled original thermostat wire back into the cupboard to the left of the thermostat (contains the meters, fuse board, phone, internet equipment alarm and so on). I ran a new cable to carry 12v to the Nest thermostat:



Access to my boiler is limited as it's boxed in in the kitchen, so putting the HeatLink in the cupboard was a lot less disruptive. Power was run from a spur, the old thermostat cable was connected to terminals 2 and 3 and the new cable was connected to the 12v output:



All connected and working:





Today I discovered NestGraph. I made a few tweaks so it supported Celsius and I now have a nice log of temperature:



I experimented with adding humidity to the graph as well, although it does make it a little cramped:



All good fun

There are normally offers around somewhere : get the main unit and a heating and hot water kit, then add trvs as you want. It can get expensive, but I think it's worth it.

thanks all for the info, really going to look into the Evohome

i watched the 1hr+ youtube video yesterday, its some nice peice of kit for sure

a si already have a cm927 Honeywell fitted, it should be simple binding the Evohome controller to it.

just need to find soem good offers now! we have 12 rads total

[skilly1]

If your house has rads with independant heating valves (TRV'S?) how does Nest or simliar work with this as each room is set to a different temp so it does not know if house is up to temp?
Also the heating system at the mmonment automatically shuts down when each room up to temp. In this case is Nest just usefull as a remote for turning heating on and off?

[davek_964]

A warning for anybody who has / is about to install Nest :

They rolled out a software update on 17th November. This has totally screwed up True Radiant. (True Radiant is the feature where you tell Nest what temperature you want the room to be at the scheduled time, and it works out what time it should switch the heating on to achieve it).

Sometimes it will work - sometimes Nest will decide it can heat your house to the desired temperature in 1 minute - so only switches on 1 minute before the temperature should be reached. Even if it's currently 3 or 4 degrees below that.

Lots of people have complained about it on the Nest forum, and apparently Nest have acknowledged (but not yet fixed) the issue.

Those of us who have Nest have had to switch True Radiant off, and adjust our schedule to the same kind of times we'd have for a manual thermostat.

Although I've generally been happy with my Nest - this is a bit poor!

You're supposed to have one rad without a TRV in the hall that will influence the room thermostat - whether it's just a basic 'stat, or a Nest etc.

Mine decided to stick the heating on 4 hours before my set point even though it was only 1 degree below temp! Weirdly I was working from home and wondered what was going on. I asked Nest and they suggested I reset the unit and re-did my schedule which does seem to have fixed it.

We don't have a room thermostat?

I was about to order Nest - I have a brand new Combi and radiators as part of our house refurb and had a cheapo Thermostat installed while I waited for the 3rd Gen Nest to be launched.

If I have this correct, the Heat link can be placed where my cheapo thermostat is, using the two wires currently connected to it? I would then run the Nest from the supplied USB power supply?
