    I’ve got a Potterton Gold 28 Combi ErP boiler that has a built in timer/controller. See pic.
    What are the chances of getting this working with some sort of smart thermostat that I can monitor/control remotely? Is it likely to have the wiring necessary to control it? There are TRV’s on the rads, but I can’t remember seeing a wall thermostat anywhere.
    I’m thinking Hive or Nest or whatever, I don’t really mind as long as I can access it from an app on my phone.
    Ideas?

    Basically, yes.

    You really havent got a thermostat now? That’s mad, you are wasting loads of gas there.

    There are 2 connections in the boiler for the controls. Must be able to switch mains voltage (most are), just choose the controls you like, and can use. They shoudl be pretty simple to install.

    Only just bought the flat. Want to get sorted before the heating is needed.
    I think I’ve made some progress by watching a couple of yt videos and looking at the wiring diagrams.

    I’m considering the Drayton Wiser Kit 1, which looks simple enough to install.

    drayton wiser is good – I fitted my own (kit 2) but I already had a wiring centre so it was plug n play onto the old wiring harness.

    I can recommend the kit, but dont know how easy it is to wire into that partivcular combi.

    not much help really 🙁

    Anything should be equally easy to wire in – as mentioned above, it’s just 2 control wires to the boiler.

    I have Drayton at home – it’s good but for a flat, if you don’t want zoned heating (i.e. smart TRVs) I would definitely consider a Nest. They’re pretty basic these days as smart thermostats go, but we’ve had one at work for years now and it’s never, ever gone wrong. Plus the thermostat is mains powered (via USB) so one less thing to worry about whereas the Drayton stat requires batteries.

    Our Drayton also occasionally seems to lose connection for a few hours although I’ve gotten round this by putting it on a smart plug which reboots it if it becomes unresponsive. They were supposed to be addressing this via a long-awaited firmware update but I’m not sure if this has actually happened yet!

    Looks like a single control wire on the videos I’ve watched with a link wire between com and live in the receiver.
    Edit – seems to depend on the receiver.

    This looks like the sort of wiring needed https://www.diynot.com/diy/threads/hive-to-potterton-28-wiring.543247/

    I’ll have a look at the Nest, but I think a wall mounted thermostat that just runs off batteries might actually by the easiest. That does of course depend on the incumbents  not knowing the batteries in it can also be used in the XBox controllers 🙂

    if this is for an AirBNB then the Nest also has the killer feature that you can set upper (and lower) limits to the allowed temp (and the controller is IMO the most idiot-proof)!

    Students! The same applies 🤣

    Edit – just seem that the Nest thermostat has a rechargeable battery so looks like it probably is favourite. Thanks @zilog6128

    I use a netatmo smart thermostat. Easy to wire in the hub to the boiler, just 2 wires. The thermostat is battery powered so will happily sit anywhere within range of the hub.
