    Sounds like with 4x the battery usage from normal (3 months vs 12, say) then you calculate the TTV for replacement quite quickly :-)

    Have you worked out whether it is the HR92 or the location?

    Out of interest, I have run this up and it is decoding data. It's not in HGI80 format of course, but probably wouldn't be hard to whip into shape.

    Looks like some activity on the rtl_433 project to decode evohome.

    I just hit the eco button (in fact I just did it this morning), 3 degrees means the heating won't come on... I suppose I could use off :-)

    Super, that gave me enough to search in the forum. I did change the batteries recently so must have done it within the 'window', I'll restart the HR92's later.

    Manual override triggering by itself

    Last night I was awake in the middle of the night and could hear the pipes creaking. Usually all my heating and hot water is off overnight so I checked in the app and could see that my conservatory...

    Octopus Energy seem to be lending some customers a FLIR looking at twitter... if you could get hold of one of those you'd work it out pretty quick sharp!

    I can't say I've noticed any delays like this. Have you done a signal strength test in all zones? I have 28 or so radiators, separate thermostats in multi-room zones etc so quite a complex system...

    I have texecom with wireless alarm. And very occasionally I get an error on one or the other but nothing that breaks anything. Not even sure it is connected.

    How are you using domictz? Do you have an HGI80? You can log the actual messages in debug mode to see what happens over the air if you are so interested.

    I'm certainly interested in your decision making and what you found. I nearly bought Wiser but settled on Evohome in the end.
    I was concerned about range for Evohome, and Wiser has extenders - but...

    I am pretty sure Wiser works in the same fashion as Evohome, logic is all local - internet connectivity influences the local controller.

    Without the internet, there is no schedule with Tado.
    The TRVs can call for heat and the boiler will modulate, but no schedule changes will take place - to lower the zones.

    So if your internet is...

    Both my current old Valliant's have their own built in pumps and seem to drive the system ok

    I guess I'm possibly conflating two things. I'd like to get better efficiency out of my heating. If that helps with the creaking pipes then great, if not I'll have to deal with them. They're under...

    My desktop research suggests that I might need an opentherm compatible boiler sequencer? (Assuming that I do actually need two boilers to heat the house).

  22. OpenTherm with two boilers & other related questions

    Hi:

    My house has two boilers wired in parallel. One BDR91 turns them both on for heating, and another turns them both on for hot water and operates the appropriate valves.

    I'm not sure if it...

    I will keep an eye on it and try and correlate to any unusual readings on the individual HR92s... it happened two days in a row and not since!

    Could be a door. Domoticz can give readings per HR92, wonder if that would help track it down.

    Odd change in setpoint shown in domoticz

    My largest zone which has 5 rads and a DT92 is showing an odd behaviour in domoticz. It appears to go to a 5 degree setpoint for half an hour. I'm at work when this happens so can't see if this is...
