The only difference I detected was adding a yearly view to the Heating Activity feature. The initial release was only a monthly view.
@GrayDav4276 Yes it’s one of the premium features. I’m a legacy user so I get the extra features without subscribing. From time-to-time it’s useful to see the heating activity, but there’s no explanation from Tado how the hours are calculated. What happens if the system has multiple zones? And does it differentiate between a zone heating at 20% and another zone heating at 100%.
You can get a paid subscription to monitor the health of your installation.
It does not even read the diagnostic codes made available by the boiler via OpenTherm (like the brandname thermostats do), not it just guesses the status by looking at the temperature response to the heating requests it makes.
When my boiler is in an error status e.g. due to low water pressure or low gas pressure, it says "everything OK" when the temperatures still do not fall too low.
