Very useful to have at a glance if the boiler is running without having access to the boiler display.
This is standard in almost all the thermostats.
I think this is a great idea and, on a related note, it would also be useful if there was an icon in the app to show when the boiler is running.
Nice idea. But unfortunatly I don't think this would be possible to do reliably. For most hot water tanks, it's the hot water tank thermostat which overrides the "on" signal from Tado to stop heating when it's at temperature. So there is no way for Tado to know for sure if the boiler is running, despite it asking for it to be.
I think this would be really useful. It would be nice to see if a specific room is triggering more boiler time than others, maybe a room I don't use so often needs a curtain upgrade or something.
Even if it didn't show how long the boiler was actually running (as it doesn't really know), it would be great to show how long heat was called for.
And show it in the graphs too, particularly for boilers like mine that only have on/off. And not just for the zone that triggered the boiler, just whenever it fired. Maybe a use a color to indicate it was triggered by another zone. I have to check every zone now to see if heat was requested, and then Im still not sure if the boiler was triggered or not.
Im not kidding when I say I mounted an old smartphone to my boiler as webcam and for audio to check activity while testing.
This type of information *might* be possible to get if your boiler us on a bus connection to Tado but that would need investigation
For non-bus systems, this will be impossible to get as Tado is simply turning on or off a relay. There is no feedback to Tado from the boiler as to how long it's running for.
You can't have a go at Tado for not being able to implement something that will be impossible for them to do. Hive or Nest won't be able to do this either.
I would say that if Tado had an option to include the radiator specs then you could get reasonably stats from that as it does know how long the TRV was demanding heat for.
