About battery lifetime
We have a holiday home in Equevillon, Jura, France. We liked the Tado system because it enabled us to control the temperature in the house when it is un-occupied & especially maintaining it above 0C to avoid water pipe freezing during the winter when it can be minus 10C outside. We purchased 16 pcs TRV radiator controllers & 4 pcs thermostats together with the internet bridge early in 2018 & the installation went "live" in March 2018 (Tado-UK ref S0039871, 28/02/2018). Since then we have never had a long battery life with either the TRV or thermostats batteries as compared with another manufacturers system (of an earlier vintage without internet control, which is installed in my house in the UK). Typically the batteries in either the TRV or 'stat units last <4 months & often about 2 months. This has been particularly difficult during the pandemic lock-down, when we have been unable to visit (from the UK). Tado claim (& have claimed since mid 2019!!) that this is a software problem which they know about, but that claim is now 2 years old & still nothing has improved. IT IS JUST NOT SATISFACTORY. We are thinking of claiming back our original investment as the product does not live up to expectations.
HOW MANY OTHER TADO USERS HAVE A SIMILAR PROBLEM?
It is about time TADO did something about the poor battery life compared with earlier systems.
