Thanks again to both of you. I'll give partial load scaling a try. I know from the beta thread there has been some confusion about which is the...

You say your new boiler was installed a year ago. Was everything working okay with the new boiler for a reasonable period prior to the EvoHome...

OK grab the latest Beta and let me know how you get on. I am now processing all the OT Status flags, like the OTGW, even if some might not be...

No, basically the Vaillants are able to handle two flow temperatures but using their own eBUS controls. However if you use the Evohome HW BDR91 to...

"solution for the variable target flows"? I hope you don't mean by using an OpenTherm monitor?

If your boiler is leaving rooms at 3 degrees below their set points with a 40% TPI duty cycle then I'm pretty sure that your boiler is struggling to...

Apologies, I have reread your original post and now realise that you have already got a new boiler, I thought you were considering changing boiler...

Vaillant with the VR33 works fine too. And now there is a solution for the variable target flows depending on DHW heating vs CH heating too. The only...

Not Evohome, but Tado on opentherm with an Ideal Logic combi. Works flawlessly.

Things have moved on quite significantly in the last few months. Have a look at evohome_rf if you have an HGI80 or combine it with evofw3 if you have...

Just thought I'd stick some findings here from my fiddlings with evohome and a cc1101 module as I was hunting for them without success so it might be...

Thanks for the replies We needed a new boiler as our old one was on its last legs. As I said before at the time I asked about Opentherm and also...

I’d always recommend using OpenTherm if you can, sounds like your installer is not familiar with its benefits.

Great if you can get the load scaling working properly, but you would need to save a lot of gas to pay for a new boiler unless you needed one anyway....

I’d vote for Intergas too, I fitted one in my last house. Or an Atag. I’ve inherited a Vokera in my new house. Out of the box it would default...

It’s on Eco. Always. Talking of DHW my supply leaves a lot to be desired. We are told that a combi gives hot water at mains pressure. It might but...

Sounds like this is DHW preheat, have you tried setting it to Eco? ► P-on (Program on): The appliance's DHW comfort function is switched on...

I have an Ideal combi boiler with evohome opentherm setup and don’t seem to have any problems. I just connected the opentherm bridge, set up the...

Can see your thinking but the whole idea of a new boiler plus the new features was to reduce the gas usage. I have today switched off the new...

I do see a value at least for debugging purposes. My DHW is not controlled by Evohome, but directly by my boiler, so it can make sense to know...

Can anyone see the need to track the OT CH and Fault status of the boiler? I already track the Flame Status.

The Official integration uses *both* RESTful (web-based) APIs (I know, I wrote it :) ) - the newer API for the best functionality, the older API...

That reminds me, I really must look at home assistant...

Thanks for the recommendations for Intergas. Not sure if that will be an option with grant funding or whether it will be a "here's what we're...

If your system has been working well for several years, why not turn off the “advanced” features and continue as before? There is no guarantee that a...

It's working like a charm! Congrats:-)

I am only 3 weeks in with my new boiler - an Intergas Xclusive 36 combi - so still getting used to it. I have connected the OT Bridge with no...

There’s also a standard integration that provides the data through the V1 API. There are InfluxDB and Grafana add ons to Home Assistant that allow...

Likewise with an Intergas Eco RF 36

OK @oxgen try now. My PR has been merged into the latest Domoticz development branch. I am now correctly handling temperature and updating an Outside...
