unnecessary hot water heating at the end of cycle
Hi,
I'm curious if you ever experienced the following buggish behavior: the hot water schedule is set up to 7:00-7:30 and 20:00-20:30. The water temperature is reached after ~15 min, so the boiler is usually not heating when reaching the off time point. But when the off time point is reached after ~2 min the boiler starts to make more hot water for a ~5 seconds and then turns off for good.
Boiler: Baxi Duo-tec Compact E 24
I've disvussed this with Tado help, they said it may be the issue of the boiler, however it worked good with different smart thermostats. I also checked the parameters of the boiler, but no related one can be found. It is obviously a problem as it leads for early wear of the boiler.

Could it be a pump overrun feature within the boiler itself?0

It has such a funtion but I don't think that this would be the case. But if it is, it's still a bug. The hot water function should remain shut off at the end of the period.

For future reference here is what happened: Tado recognized the bug and fixed it. The fix came to the wireless receiver in firmware 192.2. Thank you for that!

This seems to be an Opentherm combi boiler. Are you using it in Opentherm mode?
It seems that the Support team are still tweaking their handling of Opentherm. Interesting. Thanks for logging this in. We can keep watch for others with the same problem.

Yes, it uses OT. It took 1,5 years since first contacting them. I'm wondering how many other household experienced this issue without knowing. Maybe just me? We'll never know.
