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.
Unlikely to happen because Tado cannot reliably predict the chemistry or age of your rechargeable battery.
Regular batteries discharge in a linear manner, making the voltage drop down from 1.5V predictable. Rechargeable batteries discharge in a non-linear manner and the pattern of that discharge varies by brand and age of the battery. To overcome this Tado would need to use a sealed battery, similar to your smartphone.
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.
