This is why the correct setback temperature is critical. It wouldn't matter if the heating was only on for 10 minutes before you return if the Tado didn't let the house get so cold. It's the set back temperature choice algorithm which is part of the issue. The home/away calculations need to work for everyone not just those that are always 2 hours away from home.

There are two sorts of out. An out which is regular eg work and the out which is irregular. I think they need different methods as with the latter you'd only want to temperature to fall as far as whatever the return journey time takes to heat from. The regular out you want a temperature which is possibly lower but you still heat from based on the likely return time. That needs more voodoo and is prone to being wrong but it will save more energy as you won't be heating when you are going to be out for hours on end. Does Tado learn the difference between the two? Can it learn the difference between those two sorts of out?

Yes, I agree, I think if what we are talking about is it seeing you are out and it slipping the temperature back a couple of degrees then that may have some moments. So it comes on to 18degrees, say, at 17.00pm and then tops it to 20degrees when you aren't far away may give a bit so long as the speed of doing that 2degrees is quick and there isn't much complexity in who lives there etc.

Are you being serious? This is where my reference to one of my previous comments to Stephen Hawkins comes in (“they expect these system to have the intelligence of Stephen Hawking.”) smile, how is the system supposed to know you are going out for a short time or long time. It knows where you are in relation to the home, and that’s it. It’s better than not knowing, and will save you some money (which is better than saving no money) buts that’s all.

Even if it spotted a pattern and allowed for that, at some point the pattern would be broken (car broke down, etc), and someone would moan about that!

It will be good enough 80% of the time for 80% of the users, but that’s all. But that’s better than traditional systems or ones that only give you remote access to temperature or timer settings.

It's failing in the basic Away temperature choice though. That's my main beef. The nest learning thermostat claims to learn and set schedules so therefore they think they do have Stephen Hawking's brain wink

The tado gets the house warm within 20-30 minutes after the wake up time every single morning without fail so why cannot it pick an away temperature that will be up to full home temperature within 20-30 minutes of arriving home when it already knows the rough travel time? When I went an hour away from home it had chosen a setback of 16.5c. That's lower than the night time temperature which is rarely falls back to now, so it is again making illogical choices.

At regular intervals when you are Away it should ask itself 'what should the current temperature be if in travel time + 20 minutes it needs to be Home temperature' On comfort setting I'd expect it to work that way. In the other modes being more economic with heating and having a lower set back temperature would make more sense and assume the person didn't mind being cold for an hour or more when they got home.

Well I guess the point is, being in bed (in the house) is not the same as being out and about. Just because you are traveling towards your home does not mean you are coming home, so an algorithm to cope with that is almost impossible task. It’s always going to be a compromise, I personally don’t mind the temperature being below the target when I come home from work, because the first hour or so I’m up and moving about or in the kitchen with the oven on.

You are not wrong. Feels like a master class in straw man arguments in here lately.

A lot of the points made about "only being 30 mins from home" can be dealt with by speaking to Tado and them adjusting the rules for proximity.

Also, I find that fall back temperature varies with distance from home and outside temp/weather.

Put it this way - Tado IMHO is as smart as it gets and will be even smarter with the imminent update. Nothing comes close at the moment - Tado wins hands down.

My only gripe about Tado is that it looks ste! Nest wins the beauty contest by far.

Don't think I'll bother until there is a clear reliable winner out there that will manage water and heating cleverly and know when I'm in or out.
Sticking to old fashioned system for now. Think they all have floors.
I was waiting for someone to come up with something that just works. Then I realised you can rent the Tado and swap it when something better comes along, so you get best of both worlds.

can anyone advise if this Tado has a timer built into it as well? Il be replacing a wireless salus RT500 unit if i get this Tado. The Salus has timer functions built in.

thanks

So tado looks ok.
I had this response from them regarding my boiler potterton, hw and ch controls and thermostat

hank you for your Email, and the interest on tado°.
just checking you System, it will work tado° is compatible.

Set-Up:
When there is a Programmer (Hot Water) you would need our Extension Kit (replace Programmer)
Then the SMART Thermostat can be used Hardwired (replace current Room-Stat), or use it wireless, up to you both is possible (within the Extension Kit)
When you have a Combi-Boiler and a wired thermostat then you would only need the SMART Thermostat
When you have a hard wired Room-Thermostat then you only need to replace this device with our SMART Thermostat.

Sound right?

Salus does the same, heating and hot water and is £160 to buy outright (no charges per year).
So if I buy it outright I still have to pay a fee for the gps side of things?

I've got two Salus IT500s, one for the house and one for the annex. They work really well. My only minor niggle is that he Android App is a little clunky.

It does do hot water by the way.

No the Geofencing functions are free for life if you buy it.

I agree with you, but why does that matter, the Tado unit is pretty inoffensive, and it’s for controlling the heating not for looking at, but then I don't like too much bling smile

If you want Tado to control HW. I didn't bother.

I got the extension box to control the hot water. In hindsight I should have saved the cash. I only use the hot water on a timer through the Tado, which is what I had before with the standard heating programmer anyway.
