Python Plugin: Luxtronik Heat Pump Controller Plugin for Domoticz

[JaapB]

I'll give it a try not reporting back COP if not heating and see how that goes. Will need to update last seen on the device otherwise it will show timeout, I think.

Am testing with 3 devices and no updates if they are 0

I now take the monthly reports for energy used and energy generated to calculate the COP but that's in a spreadsheet abouth energyconsumption that I've been using for ages

Maybe it's possible to calculate on dayly basis?

Currently still testing with 3 cop devices and not sending data back when the pump is not in use and that seems to work well, as long as you disable the Domoticz Setting that is discussed here:

Have a pretty full schedule this week but will try to finalise in the coming weeks and update github repo.

Thank you for the effort for updating and upgrading this usefull plugin.

I've been using this plugin for a while now and there is just one thing that doesn't count in the right way and that's the COP since it also counts the moments that there is no heat-exchange. So there are a lot of zero's in the list.
For example augustgives 0,15 as COP while counting it the result is 4, only hot water used.

Have not forgotten about you, am busy figuring out a proper way of doing this.
Am getting really close, only downside is that I have moved towards the new DomoticzEx framework, so it will all be new devices.
In Domoticz you can transport your history from old to new devices.
Am looking to see if there is a way to automatically do that but that seems really tricky

Thank you for putting in this effort.
I will have to plan this for a day with not too much different plans to look how it will work out.

You can run them side by side, as long as you give the new plugin hardware a different name to the old one

I'm not a Heat pump expert
The 8888 port is not a web port that responds.
Have you tried the new plugin (viewtopic.php?t=44176) if it works?
