Best Wifi enabled thermostat

With evohome I tried to use ifft to do geo location last night and it worked except the Mrs is working from home today so it plunged her into an arctic wilderness of 14 deg

Is there any that will work with multiple occupant houses?

Yes, use the life360 app and life360 iftt.

It goes on all the phones in the house and recognises when nobody at all is gone etc

Evohome has a "day off" button, and you can set this to be whichever day of the week you want. Useful if your day off isn't Saturday or Sunday.

I've had Evohome for over a year now, and I'm still finding new features. I found out yesterday that the "away" quick action can have a user defined end date, so it can revert to the normal schedule on the day you plan to get back home.

Thanks both!

Looks good. As an alternative to setting schedule to 13 during the daym, and then changing it to 21 if you happen to work at home, have you tried having it set at 21 during the day too and just letting the geolocation algorithms work it out according to the cost/comfort balance setting you select?

That way you shouldn't need to manually change it, as far as I understand it. I haven't got ours set up yet, but just wondering what is likely to work best.

I used to let the geofencing take care of it but when I leave home I take the tube (which is very close to home) so it thinks I'm still at home right up until I get a phone signal again when the Victoria Line tube comes above ground at Barrons Court, I probably save myself about 30 minutes of unnecessary heating every morning by setting it to 13 degrees about 15 minutes before I normally leave the flat.

So what exactly will Tado do then?
All I want is a system that will allow me to set a temperature for

6.00 - 6.45
6.45 - 17:00
17:00 - 21:00
21:00 - 06:00

Nest couldn't do this as its minimum period is an hour and you have to leave an hour between settings - utterly useless

To be fair, for most houses and people I suspect anything less than an hour period is pointless. Your schedule doesn't make sense either as it overlaps.

What's wrong with setting temp changes at 6.45, 17.00 and 21.00?

Slight typo on my part on the schedule, now corrected.

I'm not quite sure i understand what you mean though, surely each heating period needs a start and an end time?

Are you suggesting i just set 4 temps in the system

06:00 15c
07:00 12c
17:00 15c
21:00 12c

And that nest will then run my system as i want, i tried last night to program it the way i think it should work and woke up at 4am this morning to a heating system running at 15c!!

A friend of my wife has their stat set a max of 16 deg, even during winter. And, of course, they do not have a complex controller either.

So no, you could be a real skinflint.

Mine never needs to run that hot, at 15c during the day even in winter i can walk around in shorts and t-shirt, it's just frustrating that something that should be so easy turns out to be so difficult (I got the Nest in the first place as the original Honeywell controller that came with the house wouldn't allow me to set the system like I wanted)

This is something I've been thinking about as well: how well would the above approach work with a wet UFH system?
Given how slow this reacts, I reckon geolocation probably won't work.

Currently, I'm even leaving the temperature setting at a constant level (20 degrees C) as I assume that dropping it to say 18 won't have a net benefit (as heating it up from 18 to 20 will probably negate the reduced heat generated at the lower temp)

You only enter the temp at the start time and it will stay at that temp until the next change of temperature. Mine is basically set as:

7am - 20c
10pm - 18c

Heating will come on about 6.30am to get it up to 20c by 7am. At 10pm the heating will turn off (if not off already) and stay off until it needs to heat up for the day shift again.

The only exception is if you manually change your thermostat - it will then stay at your new temp until the next change in temp. So if at 10:15pm I set my thermostat to 22c it will stay at that temp 7am.

12 and 15c are pretty cold tbh - my house hasn't dropped below 17 so far this winter - is it possible it takes so long for your house to heat up that it basically keeps it at 15c?

I'm gonna need to play with evohome

Living room 2 rads both with hr92 using the controller as the temp probe

It says rooms 20.5 but my trusty meat thermometer say it's 16 ish! What do I do?

Just now

The push in probes are more suited to contact temp reading no?

Hence being a probe and not a NTC style?

[Trustmeimadoctor]

Maybe but all I had to hand

Mine rises dramatically when I hold it to add new schedules etc

Bin your "trusty meat probe" for starters.........when was it last calibrated?

[kambites]

Could you not use one of the boiler relays to control the UFH?

Thanks for the info about the Tado earlier in the thread to those who offered it.

We need 6 zones to start with, and we have two (electrical) UFH systems. One in the kitchen and one in the bathroom.

The obvious advantage of the Tado over the EvoHome is that Tado can control electrical UFH, and EvoHome cannot (which seems a strange oversight on the part of EvoHome IMO).

The disadvantage of the Tado seems to be the price. Over €1,000 for what we need.

Im waiting on a quote to come back for an EvoHome install, but it I think on balance if spending so much money, probably better to go for EvoHome.....?

You only think you need six zones

[shady lee]

Does anyone else find it odd that the Drayton wiser kit is still unavailable at screwfix?

Trvs primarily...

A Evohome software update is imminent which will allow zones to demand heat but not trigger the boiler - exactly what you need for electric ufh.

In addition to Tado controlling the boiler and rads I also have 4 rooms with electric floor heating (2 bathrooms, kitchen & living room) but because gas is so much cheaper than electricity for heating the only one of these that ever gets used is the main bathroom. They all have their own Heatmiser WiFi capable thermostats and are not controlled by Tado. I consider it a separate (backup) system as it’s so seldom used
