Integration that works with new API and getting support from Remeha

[Gyosa3]

Hi, I've been trying hard for months to tweak the previous integrations that you've used for building this one, I was using the NodeRed version from Domaray as a baseline.
I don't know if it still works with the new API from Remeha but for me everything went to trash when I was forced to migrate...
I have contacted Remeha and ask them about their development roadmap and their support of the Home Assistant community with their new app, and if they would publish their API details.
I did not get all answers from them but a link to this integration:

https://github.com/msvisser/remeha_home

The seem to wish to support collaboration with the user community around Home Assistant, so I switched to this integration when I was forced to migrate to their new app and I must say it works well.
So, although I see you've been doing quite some effort with your integration I'd suggest you have a look at this other integration and maybe try to align if you think you have features that are missing in the other one.
I've just submitted a pull request to add what I was doing with the older API in NodeRed and it has been accepted and integrated. I think it's worth converging to a single integration so that we can all put out efforts in the same direction, so that we can put also some weight in front of Remeha developers.
For example I mentioned already to Remeha the lack of transparency of the API to retrieve the gas consumption historical data, that many people were already trying to get with the older API to no avail. And their decision to use m3 instead of kg. Together as a user community we should ask for both (for people using natural gas and those using propane gas bottles). Things like this.
Hope this helps!

I'm in the middle of this road myself too, as I recently have had installed the Remeha Mercuria Ace 4.5 Hybrid Heating Pump and the eTwist thermostat. The new remeha_home integration looks very promising, but my eTwist is still on the older Remeha eTwist app. Will have a call with my installer and/or Remeha about the conversion to the new Remeha Home App and API.

Had a call with Remeha myself and they said; if you are not migrated yet wait till the summer. We can't migrate you by hand.
They had some issues migrating people in batches and are now fixing those issues. The goal is to have everyone migrated by the end of the summer so I would suggest waiting until then.

In the integration build by mvisser (https://github.com/msvisser/remeha_home), there is a open pull request to add the gas consumption (in kWh but it is something). Check that out if you need to switch.
