Is this a bug or a feature - heating to xxx and 0.5°C tolerance?

Is this a bug or a feature?

I was informed that when it comes to relay connection, the heating will actually trigger only when the temperature difference is at least 0.5°C.

So, will the app finally change the status from 'heating to 20.5° to 'set to 20.5° upon reaching 21° even if the set temperature is at 20.5°?

This is confusing and misleading. Boiler is not heating up as it shouldn't, just the app / website is showing an inaccurate info.

I can manually fix, but why should I - this is a smart system or ;-)
