@mikeburnell a hint would be nice :)
I've just changed the batteries in the trv I cannot keep connected and now it won't even briefly connect. I've given up.
I've taken to writing 1 star factual negative comments on Amazon since the vendor has no plans to fix this limitation. That way others can be aware of the problem before they buy and maybe they will re-prioritize the bridge fix.
So far they have all been approved and I'm reviewing all the Tado items I bought on there - the central unit, AC unit, Boiler unit, and 11+ Rad units.
Such a shame they are stuck with a broken RF deployment plan.
+1 also having this issue as we have now moved to a brand new build house the smart valves that are on the first floor are now completely unreachable. (probably because of all the concrete between the server room downstairs and the first floor).
I've found and been testing a competitive product which out performs Tado with the functionality I need for gelocation, frost protection, multi zone support, tailored scheduling, weather adaptation and provides an extender.
@mikeburnell Can you let me know which product this is? I've given up on Tado too and am going to change to a different setup.
I know the general oppionion here is that Tado is awfull. But i was/am considering buying it for my house. but reading this i'm getting quite worried. How long ranges are we talking about units are loosing connection at?
My house is from 73, and internally it's primarily lighter walls, but it's 24 meters long, but i would be able to place the reciever in the middle of the house.
Any input at what ranges the problems arise? Also, some are saying that there are good alternatives, but i havent identified them?
Check to see if tado still offers the full refund within 12 months. If it does I say give it a try. Combined with IFTTT it was very useful (even if I think the interface is a pants).
If it works, enjoy. If not then you'll know what features you liked/didn't when you go on the prowl for the next one. If you've got money to burn, schneider used to do a system to die for but it was around 4x the price of what it cost me to kit out the house with tado (and tado was in the 4 figures).
I would never use Hive again, the TRVs are an absolute disaster. They call for heat and fire the boiler but then open very very slowly wasting a great deal of energy. Yes Hive does have a range extender and the room stat. and hub are fine, but be warned and have a look here https://community.hivehome.com/s/question/0D50J00005fBS8o/trv-update?s1oid=00D20000000njW3&s1nid=0DB0J0000004DKM&emkind=chatterCommentNotification&s1uid=0055I0000026cyz&emtm=1633705205221&fromEmail=1&s1ext=0 before taking the plunge . . .
I just bought a new house and was looking to buy Tado again. It's a pretty big brick/concrete house, which will take a bridge, 2 thermostats and 15 TRVs to control. After reading this thread, I lost faith in Tado completely. I was already unhappy after the child lock that took an eternity to develop. By the time the feature was released, I didn't need it anymore because by then my child was 2 years old and stopped messing with the TRVs. Other than that, the system always worked well in my previous house.
I have no faith that Tado will resolve connectivity issues in a timely matter. I would gladly pay extra money for an additional bridge to use as range extender if that results in a reliable system. What's 50 euros more in a system that already totals over 1000 euros? It's only too bad that Tado doesn't even give its customers the option to solve their problem by spending some more money.
Solved - as a last resort for my one TRV with connection issues, I bought the best batteries available. Energizer Ultimate Lithium and the problem is gone, connectivity is perfect.
Tado TRVs seem sensitive to battery quality. I tested 1.2v NiMH rechargeable batteries and they work, but quickly fade.
Lithium batteries are what's specified by tado° and this seems to make a big difference.
I now have a solution to the connectivity problem that involves having two internet bridges for covering two parts of our house. It means having to have two separate logins, but that just means having two different email addresses. It's basically fine, and just involves paying a bit more for the second bridge. I can't see all the devices at once, except by using my iPhone for one login, and my iPad for another. The most frustrating thing is the solution would be made perfect by a software change that allowed the user to have more than one internet bridge in the system. I honestly can't understand why this hasn't been proposed by Tado a long time ago.
This won't be the case for all homes, but at least in my home, the current boiler wiring has multiple "call for heat" thermostats. So for me, being able to have multiple tado hubs within the app would meet my needs. Even a quicker "switch accounts" or "switch homes" style of button in the app would be enough to make the system workable for me.
I agree that mesh could well cause more battery issues.
However, I'm not yet convinced that battery choice will affect coverage. I suspect the high voltage is only really important in respect to the demanding work of turning the motor. However, I will have a try with a better lithium battery and see if it helps.
I never really understood the push for rechargeables. While it sounds desirable with Tado when so many batteries are used, they really only make financial sense when being recharged often, once every 9-12 months means that a decent rechargable battery will take 5+ years to pay back. There are much better applications for rechargables.
Contrary to what @steve999 suggested above, I can't find any reference from Tado on their website about using Lithium batteries, it just mentioned Alkaline.
This is the only thing I could find re batteries https://support.tado.com/en/articles/3403608-what-type-of-batteries-should-i-use-in-my-tado-devices-how-do-i-replace-them
and I have noticed if I use anything less than the beefiest duracells they don't last as long and with some of the lesser ones they won't connect but the mention of lithium does ring a bell but I can't remember why.
Let me know how they go, I'm happy to grasp at any straw going.
Duracell Ultra have always worked perfectly for me
@johnbur unfortunately Ultras only last a couple of weeks on my problematic one before they're flat as even they keep dropping the connection for long periods so quickly go flat scanning for the connection.
I've also tried Energizer Ultimate Lithium. I must admit it improved connection to the smart radiator thermostat, and on first day thought it could have solved the problem, but not even 24 hours later had again a few drops in the connection. So it's not a solution.
Considering to drop Tado once for all. I still have half of my house with manual radiators valves to cover (due to range problems). I will look somewhere else.
