My Nest Learning still randomly turns on my heat/water, outside of
schedule set, without any demand from timer/temperature. Nest doesn't
show that it's ON, so I can't turn it off except by turning off the Nest
at the main supply. My Nest show NO USE,...
Same issue - system goes on while Nest says it isn't. Engineer says it
is a faulty Heatlink - turning system on without a demand. My smart
meter shows energy use - Nest shows none.
