    Be careful to make sure they're exactly the same width if you're trying to line up with pipe holes... I've replaced some of the older radiators in this house (circa 1980's I think ?) with more modern...

    Just a general recommendation for any thermostat. You want a remote thermostat to be out of the immediate vicinity of any source of heat.

    I think it's usually recommended to have a thermostat at least 1.5 metres from the nearest heat source including radiators. And obviously not above it. :)

    Last time a firmware update was released in the middle of winter and caused problems for a few people Honeywell were blasted for releasing the update in the middle of the heating season! They can't...

    20 to 30 what ? If you're talking about the valve pin position as reported by option 10 in the HR92 menu that is normal - the valve is not expected to start flowing until 30% pin position. This is...

    This is a long standing bug in Domoticz. Temperature threshold notifications with Evohome as the Domoticz device never worked for me either.

    Agreed, always go back to where you bought it from in the first instance, the same as any retail purchase.

    And yes, an E2 fault seems like a genuine fault in the device.

    What you could have done about this in a multi-room zone would be to adjust the calibrate setting on the HR92 in the room that was too cold to a (more) negative value. In a multi-room zone each HR92...
