Do what, can you be more specific? Getting an access token or calling the api or both?

I have a Elga ace hybrid heatpump maybe you see different stuff if you have an all electric heatpump, if so please share the response body with me.

This is what you asked me to do. Can you let me know how and what you need? Calling api?

This is what you asked me to do. Can you let me know how and what you need? Calling api?
In the https://github.com/tuk90/RemehaHome-Domoticz page there is a file called Remehatest.py in line 245 and 246 you can fill in your username and password. After that put a # in front of line 151 to out comment that piece of code. Fill in the following line below the outcommented code: print(access_token)

Then run the python code and the access token is printed. If you use a Raspberry pi you can go to the folder of where the script is located and do this: python3 Remehatest.py.

Now you have an access token and this can be used to call all Remeha API's. The apis that you need to call are the following.

Start by doing this get call: https://api.bdrthermea.net/Mobile/api/homes/dashboard, from the response get the applianceid and fill it in in below get call

https://api.bdrthermea.net/Mobile/api/a ... 00:00.000Z.

The easiest way to do this API calls are by using the application Postman

If you can post the response of this call in this topic I am greatfull :).

BTW, I updated the plugin to include the 'activeComfortDemand' this states wheter the heatpump is producing heat or not, I use it to dynamically turn on and off my radiator fans

@Tuk90, I just created an issue in github of an error I get since this morning:

Code: Select all

2025-02-12 11:06:06.370 Error: HK-ThermoRemeha: Error making GET request: 'outdoorTemperature'
Maybe others have the same issue?

EDIT Created a PR with the changes I made to accommodate the returned JSON changes and make it work again.

The PR changes are making it work for me yes.
I have included my JSON response in the PR so you can check and compare with yours. :-)

I put out a new version wich solves the outdoortemperature for both Boilers (CV) and Heatpumps (thanks jvzd!), furthermore I added the seasonal efficiency (SCOP) for heatpumps as a new device.

Works like a charm! Thanks for the fix. Also the SCOP is present.

Is this a generic issue and are others having this issue too ?

Maybe it's an idea to add a try: around this call to avoid the tracestack to be displayed each minute, and just display the lastline error.

Hi,

It seems that the authentication method has changed:

Hi,

It is a general system failure, if I logout and try to login again in the app it fails.

Re: Remeha eTwist

Posted: Tuesday 06 May 2025 8:51

And it is working again. For the future I might need to implement to use the refresh token instead of a fresh authentication when the access token is expired
