Hi,

I have had the above combo working for a week or two but it has now stopped switching on the heating. All Tado components are showing as connected.

I refitted the old analogue timer and the heating works, reconnected the Extender and heating not working again.

The Extender is showing as connected but does make a slight chirping noise in synch with the breathing LED, is this normal, I can’t say I noticed it previously?

Thanks,
