Anyone who already uses tadoº Smart Thermostat, does the app shows actual energy consumption or only saving? Screenshots would be awesome.
As most boilers are not able to measure and report the actual amount of energy they use (unlike a gas or electricity meter), it isn't possible to measure the actual energy consumption. Instead, assumptions based on local heating averages, average (non-smart) heating schedules etc. are made to give you an estimate and a baseline.
We are hoping that the smart-meter market will soon bear some fruits that would allow a more accurate measurement to give you a clearer picture of how you use energy.
