    If you have stroke mode set to 1 in the HR92's, and they are reporting valve position 0% in option 10 (fully closed) and the radiator is still continuing to heat up then your valve bodies are either...

    It won't be the HR92's to blame - they can't cause a knocking noise.

    However they do make very fine adjustments compared to regular manual wax pellet TRV's, and also hold their position constant...

    Did you have load scaling on Normal or Partial ?...

    Did you have load scaling on Normal or Partial ?

    I find Normal too aggressive, (zones struggling to make their temperatures as you report) but partial works just nicely for me and helps avoid room...

    Could one of the switches in your zone valves be faulty ? (Leakage due to burnt contacts maybe ?)

    I assume from your diagram you don't have a dedicated boiler relay but just have the two switches...

    Short answer is no, you can't do what you're trying to do. In a multi-zone Evohome installation every zone must have an actuator, you can't just have a zone with a temperature sensor and no actuator....

    If an update happened and you saw the control panel within about 30 minutes of that then yes you'd have egg timers for many zones.

    Egg timers for many zones at once means either the device has...

    If there's no lights at all even when you press and hold the button it sounds like it's dead I'm afraid!

    My three have been going 6 years now without any problems so I think you're just unlucky.

    Correct, Away mode disables hot water completely.

    You say your system was scheduled to be "off" but later you say your Away mode is configured to 18.5C.

    Clearly that is not "off". It's...

    Haven't heard of them. What do they do ?

    Is it similar to Home Assistant ?

    There's no way to read the hot water set point through the Honeywell Web API's, the only information made available is the currently measured temperature and whether the hot water schedule is...

    Same here.

    We just turn off all our downstairs zones at night (5C in the schedule) and rely on Optimal start to figure out when to turn them back on again to reach the target temperatures at the...

    Alkalines in my DTS92 seem to last a couple of years.

    They do have problems with the battery contacts though, if you thump it on the side and it reboots you might need to check the tension of the...

    The harsh reality that nobody really wants to admit to is that without installing something like an automatic tempering valve (which is typically best done on each hot water outlet) there is no one...

    I tested an HR91 sample when they first launched but one of the reasons I returned it was this issue - the stroke is insufficient for some valve bodies and there is no Stroke 1 equivalent setting...

    If an HR92 is not generating any heat demand, reboot it by removing and reinstalling the batteries.

    It's an occasional glitch in the firmware of the HR92, I've seen it maybe half a dozen times in...

    I only have an Evohome system so I don't know. Give it a try! It will either work or not. I use the watchforstock Python client bindings - they work with both API's.

    I did something similar. I removed the original wall thermostat, installed the BDR91 back near the wiring centre and re-used the old thermostat wires for power for the Evotouch wall mount.

    Most normal people would agree with you, but Honeywell don't.

    None of the temperature displays on the Evohome devices including wall thermostats show the real temperature. They are all biased...

    That doesn't make sense. When you replace the motor head you still have to re-wire it, it's just the valve that stays so you don't have to drain the system down.
