    They also get very hot even when out in the open (flow temperature plus power dissipation of the pump) so I would imagine that having it trapped under floor boards with no way to cool properly would...

    Ok. Yes it has to go between the output side of the pump and the return line. Strange to have the pump under the floor boards, I've never heard of such a thing...

    Most boilers have pump overrun so when the boiler demand signal is turned off (BDR91 etc) the pump will continue to run for a few minutes. If all the valves are closed and there is nowhere for that...

    I don't understand why you would need to rip up your floor boards to install an automatic bypass valve. They're usually installed within about a metre of the boiler so unless you have a very short...

    If it's only happening in one or two zones, choose a random time in the hour, remove all the batteries from the HR92's in the affected zone(s) and then refit them.

    This should fix it. Honest. :)

    I think we're talking at cross purposes here. I don't use Domoticz. I was referring to the over the air API's only.

    I was just trying to point out that the V1 API does still report high resolution...

    You misunderstand - I know about the 15 minute reauthentication issue that's been there for quite a while now. watchforstock's V1 client deals with this gracefully so it's able to reuse the token...

    What temperature does it override to ? The previous set point for the schedule ?

    Are you sure ? I'm still receiving high resolution temperature readings using the V1 API with Evohome python bindings. I use it for my graphing.

    Ergh... where did you find this out ? Do you know...

    Oh, that's disapointing to hear.

    One of the things that attracted me to OpenTherm if I ever ended up with a new boiler is I hate the 10% minimum heat demand threshold the Evohome system has when...

    Another example of the outdoor temperature of the Evotouch being waaaaaay behind reality.

    It was quite cold last night and is clear and sunny today. At 10am this morning my weather station is...

    That was what I thought before I set up a 24/7 independent monitoring system to monitor the wireless transmissions. And it has shown conclusively that in every case where I'm getting a "comms fault"...

    Perhaps, but all these variations on a theme just result in the conclusion "poor receiver" in the Evotouch.

    Perhaps, but that wouldn't explain why my independent monitoring system mounted about a metre away from the controller can always hear the CS92A messages that the controller misses. Unless the...

    In my case I think it is indeed the controller to blame. I have had the CS92A replaced and also have moved it several times, never has it been completely reliable.

    However when I've compared the...

    This fits in with what I've observed - unreliable reception of the sensor by the Evotouch.

    Unfortunately in my case they are only about 5 metres apart with one solid wall and one wooden frame...

    Ah yes, if the white base is not screwed down onto the valve body properly it may not push the pin down far enough to totally close it.

    So it needs to be down enough but not enough to damage the...

    I've had the entire CS92A kit (including sensor probe) replaced under warranty early on. Didn't help.

    The Alexa integration can only set a basic override - eg until the next scheduled set point. You can't set a custom end time, nor cancel the override. (You can only override it back to the original...

    Can you give a bit better description of what symptoms you're seeing ?

    Pairing of devices shouldn't be lost due to a firmware update.
