For a few days I receive an 403 error when I try to use one of the Tahoma devices in the Homey app When I remove the somfy tahoma application and reinstall it, it works again for a few hours but later the error returns. Does anyone have an idee?? I use the Homey app and have Homey premium without…

I have the same errors with Somfy in the Homey app. For a few weeks now. Tried all the usual troubleshooting but the errors keeps coming back.

Yes me too. I removed the application but then could sign on again. The i got the 401 error. For now i just wait and be patience. When a solution isn’t live soon I’ll remove the Homey app and quit my paid subscription.

Yes me too. If no explaination or no solution I will end mij Homey subscription.

And reading the post from Adrian Rockall it seems to me it’s due to Homey Cloud using the same IP address for many Homey Cloud users. The post is from 7 october and appearantly since the apps from Somfy TaHoma and …

30 Oktober en nog steeds de 403 melding. En nog steeds geen bericht van Homey wat hier aan gedaan wordt.

Homey won’t respond as I write the app and the issue is caused by Somfy’s security measures, so there’s nothing Athom can do. Somfy are now concentrating on the local API, so they aren’t interested in making any changes. I published a new version a few hours ago to try and solve the problem, but t…

Hi all, I’m facing same issues. Just removed Somfy from Homey and reinstalled. I do get the option to enter my credentials, however I receive following: ”blocked for 31232.052000045776s”. I can log in dircetly into the Somfy app however, so the block is not from them. Please let me know if anyon…
