Make the "energy savings" report more honest
The energy savings report trumps the times where, implicitly, the system has saved money, or meant the heating was on less. However, it doesn't include the times, or nett out, when the heating was on unnecessarily due to Tado pushing users to turn the heating on in already warm enough rooms (i.e if the temperature is between about 18 and 20C).
A more honest report would include the unnecessary heating Tado pushes its users to use, as well as the times the heating was off, but might otherwise have been on. It is Tado's decision to push people to heat rooms warmer than needed, but that decision shouldn't be greenwashed.
