This has to be fixed. I have 11 around my house and replacing 11 sets of double AA batteries every 9months or so is ludicrous and wasteful, goes against the green savings made elsewhere and the credentials of this organisation. Please fix. Soon.
Please make rechargeable batteries usable with Tado. It's amazing it's not already implemented.
Completely crazy that an energy efficiency product doesnt allow use of rechargeable batteries.
Given the level of discussion, both here and other places, I am staggered Tado have not yet implemented a fix so that we can use rechargable batteries without having to have the 'low battery' notification constantly on.
At the very least, some proper feedback - indicating either an estimated implementation date or a technical explanation of why it can't be implemented, should be provided.
Come on Tado - show some customer consideration!!
I'm looking at adding about 10 TRVs. The only reason why I'm hesitating is due to the rechargeable batteries issue.
Come on Tado , start reducing waste and be a bit more part of the circulair economy! Within a couple of years the non rechargeable LR6 Alkaline battery is not the standard anymore. Do you know that companies like IKEA stop selling these type of batteries? It makes no sense that Tado isn't supporting rechargeable batteries yet. Please change this soon. https://newsroom.inter.ikea.com/news/ikea-to-remove-non-rechargeable-alkaline-batteries-by-2021/s/bd0e6e55-ccc4-46d6-8b37-bb1f9dfa24ff
Please can you prioritise this ASAP. it feels totally wrong with everything that is going wrong with the planet at the moment to be discarding so many batteries every year. I bet Tado can calculate the number of tonnes of batteries being discarded each year across all their users - makes me feel ashamed. Perhaps they could be transparent and at least publish this figure so we can see the size of the problem. This should be key objective for the company (along with reducing boiler energy consumption).
I have several zones and this is the key issue that is stopping adding more radiator thermostats. What about an option to set the battery type and send low battery reminders based on a conservative timescale (say 4 months) rather than measuring voltage (if the current devices cannot accurately determine discharge of NiMH).
appreciate your help on this.
Come on tado, it must be possible to make a battery sensitive fix or a digital switch in your program to adapt to (at least quality brands, recyko, eneloop) rechargeable batteries. We can’t keep throwing away alkalines!
Please fix this. It should be an easy software/firmware update. im not going to buy new batteries for 10 devices every 6 months. thanks
What is the actual minimum voltage before a TRV stops functioning? How long does a rechargeable work until it reaches that level?
If it’s a really short time, then rechargeables aren’t really a practical solution without a hardware change, but if it’s a sufficiently long time, then the only reason not to use them is the low battery warning and that would just be a software fix.
I rather suspect it’s the latter so tado need to do something about that. As has been pointed out, this system is supposed to be better for the environment, yet chews up batteries at a prodigious rate. I have about 15 of their TRVs and battery costs WAY exceed any possible savings their system is supposed to provide and that they keep telling me it does.
Speaking of which, how are these savings measured? Compared to what? It’s obviously just marketing BS as they have NO possible idea of what the energy consumption would be without tado, so they CANNOT POSSIBLY calculate any changes, for better or worse, due to the use of the tado system.
@UKenGB Interesting comparison for me. 8 tado TRV on original batteries just over 1 year and still showing OK!
@UKenGB I'm using good quality rechargeable batteries in mine, Eneloop Pro or equivalent and they easily last a UK winter/heating (~6-7 months) season. I just charge them all in the summer. I have 9 TRV's (6 zones), rechargeable AAA in two thermostats (one main one and the other just as temperature sensor to give smoother temperatures in the lounge) also are fine, these don't even show as low.
Also be aware that Ikea LADDA AA batteries (which are highly likely to be rebranded Eneloop Pro) have a cheaper casing which makes them slightly too fat to work properly in the TRV's. They are also a pig to get out again so best avoided.
+1 for rechargeables.
the main purpose of having tado is to reduce emissions and pollution. show how much you care for the planet and add compatibility with rechargeable batteries.....please.
Mine doesnt even detect low alkaline batteries. Just had the boiler on all night as a TCV called for heat but wasnt opening t0 achieve it.
Just a little extra information on the use of rechargeable batteries, I am using Eneloop Pro AA in Smart Radiator Thermostats (SRT). Generally the low battery indication is working ok with these batteries. However, if the SRT firmware needs updating then I have been getting a constant low battery notification, even if the batteries are still ok and the SRT is operating without problems.
I am not sure how often firmware is being updated, but I had at least three different versions on my SRTs and eventually I noticed that the three SRTs with constant low battery alerts all had old firmware. I wondered if the old firmware was somehow the cause of the low battery alerts (thinking that maybe the newer firmware was managing the rechargeable batteries better). However, when I questioned Tado about the problem they mentioned the low battery voltage was stopping the firmware update from happening. Freshly charged Eneloop Pro batteries managed to get one of the problem TRVs to update its firmware, but the other two problem TRVs needed fresh alkaline batteries to get the firmware update.
It seems that the firmware update will not happen if the battery voltage is not above a certain threshold. This is a sensible precaution to make sure the battery does not die during the firmware update process.
If anyone from Tado is listening I think it would be better to have a separate "Battery voltage too low for firmware update" message rather than using the generic "low battery" message.
One more vote to rechargeable batteries.
