Hot water on, CH off. All radiators are hot.

Since this morning all my radiators are hot when hot water schedule starts.

The problem started from around the time the update was installed on my phone, based on the temperature monitoring chart of the app. Valve appears to be fine -- it was also replaced just 6 months ago.

So I am left wondering whether the app is broken.The heating is coming on for the duration of hot water, but the chart shows no heating during those periods.

Right now the house is at 22°C even if the target temperature is 20°C and the app chart still shows no heat is being used for CH.

Again everything was working fine until this morning.

Anyone else experienced this?
