Anyone seen heating staying on when app has turned it off?
I have Smart Thermostat extension kit to control both heating and hot-water.
I have recently noticed this situation: starting with both heating and hot-water turned on, then turning off heating, the extension kit continues to "demand" heating. The app says heating IS off but it is not and it is not controlled by smart thermostat either.
When hot-water goes off, after about 60 seconds, the extension kit then switches off the heating system.
I have checked this by testing signals in the junction box and listening for the relay clicks etc.
I suspect a software logic bug - any thoughts?
