    That would be highly unlikely as the Evohome components communicate over 868MHz and even a Zigbee source is spitting out harmonics these should not hit the BDR91. It is very possible however that you...
  2. While the BDR can hold up to four binds, double...

    While the BDR can hold up to four binds, double binding sounds like a source for error as one (the `zone`) is supposed to control the other (boiler). I wouldn't even try it. I'm not really aware of...

    Nice of them to give ahead warning this time, even if only on a channel where no person in their right mind should want to be on. Either way, at 07:39 GMT still no miscommunications logged and it...

    Sort of, yes. Your input needs to be sent to the HR92 which then in order needs to instruct the BDR91. The delay comes from the fact that the HR92 is not awake all the time but is only available for...

    Honeywell refers to this as the `base plate`. Two versions exist, the standard 30mm that comes with the unit and a replacement 28mm version (ACH28). It must be noted here that I've never seen the...

    The controller does contain a thermostat, as far as I know it won't serve as a zone actuator though. The concept is a bit fuzzy, but the controller is more like a smart remote to the HR91/92 units...

    Correct. Might have been somewhat clearer: left column are the connectors inside the BDR91, right column the connectors from your junction box.

    I suggest you leave the wiring in place though, just...

    Quick search for an installation manual gave me the following link: http://www.free-instruction-manuals.com/pdf/p4734564.pdf

    Seems like your setup is best described by #4e. Installing the BDR91 is...

    Is it a wired thermostat? There appear to be multiple wiring configurations, so you should check the wiring first. Simplest version involves a 2-strand telephone wire towards your boiler and if that...

    Maybe worth noting that the tips given depend on the controller type and software version, e.g. the controller I have does not have a `System Summary` menu entry and Eco is fixed to 3 degrees below...

    Server was down from 10:18 CET. At 13:09 I received the first sign of life and was able to establish a session at 13:17 and retrieve data. This lasted until 13:22 and then it started returning errors...

    I suppose this will mostly depend on how much heat the boiler can generate. In my case I am on city heating and that is practically unlimited heat supply. In the cold season I heat the children's...

    I'm somewhat puzzled by the purpose of this function. Is this for homes that have no insulation whatsoever?

    Well, according to you it isn't and according to me it wouldn't. Seems to me we are pretty close to full agreement.

    Apparently I am very bad at explaining.

    The Round wireless is a zone controller and as such it will signal the valve unit whenever it reaches one of its trigger points. Instantly.

    Well, allow me to explain to you then why I think the advice was wrong.

    Evohome is designed as a multi zone system where every individual zone must be able to generate a heat request to your heat...

    Not real sure how you ended up with Evohome to control a single zone and in fact without a valve for that zone. Evohome isn't designed for this and it is not surprising to see overshoots as well as...

    Likely better to ask what hardware type is used. A source scan reveals that "Fault Logbook" is part of EvohomeRadio, so you won't see this device on Web or Script.

    True.

    That said, before I had Evohome I used to set the living room at 24C just to create the trigger for the heating to come on and allow the radiators upstairs to get hot. If the UFH in the...

    Well, as far as I can see the Evohome installation has had no effect on annual usage, although in the year of installation (2016) I did actually come down 3GJ. I've been consistently on 17GJ per...

    Guess you answered this yourself?

    Eco mode subtracts 3 degrees from the set temperature, unless this puts the zone below the minimum. I agree that it is counter-intuitive that this behaviour is...

    As far as I know those parameters should work, but it might be off because you are not sending the expected format (the API likes JSON, not a URI parameter string). A second problem may be that just...

    That is the newer API and it might be worth while noting that that application ID is obsolete (i.e. it also works without it).
