    Good points. But the thing about 2.7 times the power isn't really fair because I'd expect hydrogen production to be sited close to sources of zero carbon electricity (solar farms, wind farms, tidal...

    The thing is, for now at least, gas is still the cheapest way to heat a home. But quite some factor. Things like heat pumps currently only make economic sense if you're using LPG or heavy oil for...

    One day I'll wireshark the app and see if there's a way of pulling the data by pretending to be a phone!

    Last of return temp is REALLY annoying. You can't get it via Opentherm either. But the sensor is there because you can see the value in the InComfort app.

    I went for Intergas. They play really well with Evohome via Opentherm, and I liked the mechanical simplicity (no diverter valve, for starters - they always seem to fail with Combi boilers).

    To a point. But ZigBee kit can be battery powered (for temperature sensors etc.) whereas Wi-Fi will usually need mains power (there are a few exceptions such as Cricket).

    You need to get past thinking about heating radiators up. Rather than applying overrides, adjust your schedule to get your rooms to be comfortable at the times you use them. That's how Evohome work...

    If the room wasn't losing heat and it was within 0.2C of setpoint then no thermal input is required.

    What were the domoticz measured room temps at the 30m and 60m points? Was it cooling or staying constant?

    I use Smappee for monitoring my gas meter. But the gas monitor only works in conjunction with the electricity monitor.

    Also, they seems to be going more upmarket, with installer based products,...

    Same here. Their servers or connectivity (hard to know which) has been up and down several times this evening.

    I know my internet connection has been rock solid during this period because there's...

    I have an older Intergas boiler and don't see anything even remotely like this behaviour. Something is very wrong with your setup - it shouldn't be doing that, and it isn't doing that by design.

    If the MITM weather API is using “London” as the granularity then I can understand some of the problems!

    Hopefully it’s using postcodes (perhaps minus last two digits). I wonder how many of those...

    But there's no need for it to be different. My point is that the controller can use the same setup as the millions of apps out there.

    Another thought. Get the local Evohome controllers to poll Accuweather directly. Cut out the middle-man and the problems should go away.

    You can still control this centrally by pushing out the URL...
