    Looks like there's two conversations mingled here!

    On the OTGW front, I used it (the Russian Orange Pi version) with an Intergas boiler and saw no difference in boiler temps with or without the...

    Do you have hot water? If so change the battery in the temp sensor.

    In the past we’ve seen a couple of instances of a dying HW sensor causing a fault like this.

    It may not be, but for the...

    I kind-of disagree with that one. The main install manual is pretty damned good, I reckon, with a good mix of the simple and advanced stuff.

    It'll never cover everything, and it would be a mistake...

    Thanks for the update Rameses.

    You do need a new term for Zone Scaling, whatever it is!

    Scaling has nasty connotations when it comes to water based heating!

    There's lots of new, shiny, pretty things on the market, but I've not heard of any that are as good or as reliable as Evohome.

    All depends what you need, I guess. But for me comfort and...

    Much of the Evohome 'logic' is contained in the TRVs.

    I suspect that artificially messing with the boiler flow temperature will cause havoc with that learned data.

    I've never had cause to think...

    Agree with all of that, but I would point out that Evohome is no longer Honeywell - it's now Resideo. And I think *some* of the lack of attention to the product lineup has been caused by the focus on...

    In the app select the zone, then click the temperature. Then the black clock at the bottom. Then click cancel.

    You don't need to set the default temp.

    But that red cancel isn't intuitive. It...

    Heat pumps and underfloor heating (especially when heating a slab) are a bit like night storage heaters, but perhaps even more laggy. You need to predict when cold or hot days are going to happen and...

    Perhaps the dead HR92 died when the room was last heating up, and just after sending a 100% heat demand?

    It's a replacement for the exiting Yahoo! group, so one in one-out.

    I don't think it'll affect here.

    Might be worth using a fan heater - on the cold setting - just to redistribute the air around the room and mix things up a bit. Only needs to be a small one, and you could hide it away. Put it on a...

    I find that (even good quality) tape tends to go yellow and leave a hard dry coating when used close to a heat source.

    Horses for courses. I guess it depends on just how destructive the particular...

    Yeah, but Earth is there for safety. I wasn’t convinced that “there’s no alternative” was a good reason to use it for power.

    I also suspect the switches would be destroyed next time an electrical...

    I was never happy about how Den lights witches were wired. They used Earth as Neutral.

    Other manufacturers *could* do that, but they don't. For good reason.

    That would only be true if you had HR92s on all of your rads (and an ABV).

    Without them, if you did as you've described, you'd have those rads coming on every time your hot water tank needed a...

    Den Automation has gone titsup

    According to The Register (who are usually right about these things), Den Automation has gone to the wall.

    It's a shame - the products had a lot going for them. But I'm not surprised. Wearing my...

    There's an option sensor that you can connect to the DHW incoming (I use it as I have a pre-heat tank). Perhaps it's that?

    Difficult to know because Intergas are a bit crap at exposing these...

    That's what wireshark is for!

    The bigger problem will be certificates. Assuming this stuff is properly secure. Which might not be a good assumption!

    Very interesting.

    That kit is REALLY useful if you have damp issues in your home. Also good for landlords to fit in rentals.
