I think that's what the HGI80 was originally intended for.

Like I said Ally, it's hard to know whether there's still delays when thee's no big morning ramp up in temps or evening ramp down. I think we'll need to wait until Spring before the problem is...

The outside temp problems are caused by delays, and are most noticeable when the days are warm and the nights cold, during the evening and morning.

This time of year when the temperature is...

Maybe it doesn't happen if there's a full comms outage (perhaps if the session is down then the remote end just drops the change). But I have seen it with 'iffy' comms. In one instance where my ISP...

Or your broadband.

Or the WiFi connection to your controller.

So many possible causes. Some of which are easier to eliminate than others.

I'm pretty sure it isn't. What's you're calling tap water temp is exactly that. Heating return is something completely different.

It works fine, and you can pick up the legacy electricity monitors on eBay.

I might even have a spare one here, somewhere...

I'm using the Smappee gas monitor with the old school (pulsing green LEDs) Smappee energy monitor. All works fine.

P.

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...

Interesting read here from Siemens : https://www.siemens-energy.com/global/en/news/magazine/2020/repurposing-natural-gas-infrastructure-for-hydrogen.html

There's already a roadmap to add 10% hydrogen to the existing mains gas supply.

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.

These are the devices that it offers to Domoricz.

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).

And ZigBee can be meshed...

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?

The AVS90 always reminds me of a Doctor Who Cyberman.

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,...

Isn't the a big brother for the BDR91, not very well publicised, but which takes a bigger load? Can't remember the name....

P.

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.
