Tado is currently testing (and apparently fumbling the rollout, as some users are already locked out) of a new subscription of 1£ a month per household. Without paying for the subscription you will apparently lose all access to the app and its most basic features, such as room temperature control and scheduling.

Ahh, of course, custom hw with custom software, everything is wireless connected on the home network, but for some reason you must connect to third party cloud, allowing them to brick your system with such a speed, like it was some future technology.
