Hi Klaas, if all is well, region03 should be in the list and should work.
Did you use the correct web credentials?
Is Region 4 working?
Since the new web option every time I add a device I get the following error:
Anyone knows how to solve this?
Hello,
I try to connect via web with region03 to my system, returns no visible devices.
But, I connect with the other option - system after 2023. Unfortunately the data cannot be retrieving.

hi @NICA_ADRIAN
Can you share with me your web credentials via DM please so I can take a look?
The API integration will be removed in the new version, so please do not use it anymore
Please share with me your credentials so I can have a look.

Iâve published a new test version yesterday, can you please try again?
Hello,
I have send you the details.
Did you have time to look on the issue?
Thanks!
I installed the version and it works without problems thank you very much
In my case the new version 2.0.11 crash every update: 3de12cd9-e920-47d0-bbe4-e03b04f909f7
I finally got version 2.0.11 working for the most part. Only thing is that the #Effekt doesnât get populated for me when I use The Power Changed. I hope this will work soon.
Works perfectly fine in the meanwhile. Thanks!
After update to .12 version no change (seams not anymore connnect) so i try to re-add device but now no user and password are accepted that works on .10 version. Hope in the .13 ![]()
In my case used reagion03eu5.

Now it works perfectly! Thanks so much!
app updated and now the solar system is unavailable.
Error retrieving data (TypeError: response.data.data is not iterable)
Did you change a setting for example checked the battery?
No changes.
I noticed that on fusionsolar website they added a captcha? maybe thatâs the issue now?
LE: this is the issue 100%. If you remove the device and try to add it again you get invalid credentials and no captcha.

If the captcha appears, just login with it and the issue will be resolved

Thatâs the problem. There is no captcha in the Solar app login.
tried reinstalling the homey app and readding the device.
upon logging in with the web credentials I get âcannot read properties of null (reading âlengthâ)â error.
I donât have the âinvalid credentialsâ issues reported by @Valentin_Ciopei but still cannot add the device. see my reports on github issues 62 as well.
