  1. Positioning the ABV "as far away from the boiler...

    Positioning the ABV "as far away from the boiler as possible" is overrated IMHO. My ABV is only just past the (external) pump, so a total loop length from the boiler of under 2 metres or about a...

    Yes, because you bound the boiler control function to your hot water valve. So every time the heating calls for heat it will heat the hot water too - even if it's over temperature...

    Sorry but you still have it configured wrong and still don't understand how it should be working.

    Unless you have a BDR91 which is connected directly to the boiler, you do not bind a boiler...

    If you only have a hot water relay and a heating relay you should NOT select a boiler control relay or bind it.

    You will need to clear the bindings on the relays (15 second press of the button...

    Personally I would unregister the device from your TCC account and then (if you don't plan to use Evohome in the future) close the TCC account as well. Let the new owner create a new account and link...

    Just because your HGI80 received a temperature measurement from the zone doesn't mean the controller did. Presumably the HGI80 is not in exactly the same location in the house as the controller so if...

    I assume you are graphing temperatures from the API ? If so, a temperature of "128" degrees actually means "unknown" temperature. You will see 128 at the same time that the controller displays an...

    You say you've bound the DTS92 to the BDR91 - either you're using your terminology incorrectly or you've done the binding wrong.

    You don't bind a DTS92 directly to a BDR91 with an Evohome system -...

    No settings will be lost by rebooting the controller. It will take a while before all zones are showing temperature readings however - typically around 30 minutes. The red warning LED's on the boiler...

    I would try rebooting the controller first. Just pop the battery out for a few seconds while it's off the charging stand.

    It will take a while for the other devices to sync with it (more than 30...

    For a single-room zone all the HR92's in the zone will display the same temperature measured by the one sensor in the room whatever it is. There is a transmission delay of a few minutes so the...

    Got it to work, however I had to make changes to one of the lua block files before it would work. See my post on the linked thread. Luaradio and the necessary dependencies are quite some work to...

    I could easily use an online weather service using pywapi - I already use this in my evohome-munin graphs to get the local forecast temperature, and it's literally about 5 lines of python, however...

    Thanks, that looks exactly like what I'm looking for! :)

    I'll report back if I get it working.

    If the system is that vulnerable to "RF signals" or interference in such a way that it would cause an override, then the over the air comms is pretty shoddy and would lack even a CRC.

    Since the hourly check-in time goes from when the batteries were inserted in the HR92, and any HR92 in the zone could trigger a phantom override and the controller then propagates it to the others,...

    Then what you are experiencing is the infamous "Phantom override", where the set point can get reverted to the previous one in the schedule a few minutes after a set point change.

    Some things are periodically resent, some are not.

    If you make an override directly at an HR92 it sends a set point change to the controller within a few seconds - and every hour (counting from...

    Hmm..

    No, the controller only sends set point changes to HR92's when there is a change in set point. Additionally identical set points in a row do not send out redundant set point changes.

    So...
