Or better still, go for the older version for £60 from Toolstation, works just the same and the whole point is you don't need to use the thermostat directly so whizzy lights do no more than look silly.

You need hive2 thermostats and the V2 hub for multizone. Add the receiver first and then the second thermostat will marry up to it.

If you've got a combi boiler use the single channel hive (heating only). If your combi boiler uses volt free or has a 24V external control, using the dual channel (heat & water) will damage your boiler.

Surely it is as simple as adding a second thermostat and receiver on the "manage devices" page in your hivehome account?

Documenation supporting this? I can't find anything on this subject officially for V1.

Thanks, understood, thanks for taking the time to reply.

Oh dear, oh dear, perhaps you should do some of your suggested research before making dumb statements like that.

You can indeed add multizone to the v1 if you're one of the minority who require it, the function was added after the v2 came out but it was just a software change that allowed it and functionally there is no difference between the two, just adding another stat and receiver.

You need plumbing, from the boiler you'd have two powered zone valves, each one is called by the relevant stat to open/close.

It's a big investment if you don't have it in place so probably something you'd plan for when changing your boiler. Obviously it will improve your efficiency hugely as you can heat relevant floors at the right time, coupled with TRV for fine tune. But like all things you're probably looking at 10 years to get the costs back via savings.

See my reply.

Also is this compliant with Google Home ? I thought it was but now can't find Hive on the google site

I only need hot water and not heating because I have a combo boiler. Can I still buy heating and hot water. But not use the hot water part? With 20% discount it's £84 Amazon warehouse deals.

presumably you need to have compliant heating system for this to be the case - ie that you can heat just upstairs or down stairs ? sure I have thermostats on all the rads but the feed from my boiler goes both upstairs and downstairs simultaneously and cannot be directed one way or t'other. OR is the heating system like mine but the 'temperature trigger is in two zones, ie if it gets cold up stairs or downstairs then the heating starts but again goes to both areas (even if it does bypass rads if due to thermostats) ?

That's not true.

With V1 you can't multi-zone it, so if you live in a larger home or newer home you'll likely need V2 which can operate a second thermostat.

In my house V1 would be useless and I'd hugely reduce my energy efficiency, a predominant reason for buying smart stats.

Perhaps research before leading people a merry dance.

With installation if you'd like:

Its because it's out of stock right now, but it was there.
I'm gutted as well as I came home to buy it but it's gone. But the warehouse deal has 20% off so I'm good

OP should change the title, it says Heating and Hot Water, voting cold

Isn't this the "USED" price? for £105

I got the hive toolstation deal a while ago, and I can confirm once it is set up, you never need to look a the thermostat. So the extra dosh is just for the fancy looking lights, etc.
As far as best between Nest and Hive, the biggest difference I can make out is that Nest is more intelligent, ie it knows when you have left the house and can learn your movement patterns and adjust accordingly.

With devices like this and Alexa, you can begin to see why Skynet in the Terminator became so pervasive.

Yep, sounds like it though as I said you can fit either and just have one circuit that doesn't do anything. I'd say it could be handy if you want to take it with you when you move but I'm sure there'd be something better out by then anyway.

Just to put it out there. British Gas charge £100 to install it. If you don't buy the one with it included

which one is best nest or hive?

I have a combi boilder. have one faceplate that I can set schedules on near the boiler and then a temperature gage near the hallwall. I think I just need the heater version.

Works a treat, just received my Dot, ran the discovery and away we went.

As UnknownConcept hinted, if you have a separate water tank for heating you'll need the double one, if you have a combi boiler you can actually use either, you just won't have anything connected to the water side. If you have multiple heating zones it becomes a bit more complicated but I don't have any experience of that to make a recommendation.

I think you need to check your boiler about which one to use

Im planning on using this with Alexa, I have a new build house (build 2013) so guessing ill need the hot water and heating edition. Wont really be using the faceplate much so guessing the old one will be fine for me.

Absolutely nothing other than one has a normal looking, white plastic, monochrome LCD display thermostat and the other has the horror show in the picture above. Once installed you control it with the Hive app or whatever flavour of home automation software you fancy, even Alexa, no need to touch or look at the thermostat. If you're not going to use it remotely there's not a lot of point.

Or better still, go for the older version for £60 from Toolstation, works just the same and the whole point is you don't need to use the thermostat directly so whizzy lights do no more than look silly.

How much is the average install costs of this
