I have setup the Somfy Tahoma Switch with the IO motor of the sunshade on the porch. With the Tahoma app i can control the sunshade. I installed the Somfy Tahoma & Connexoon app on the Homey and configured the app with the login credentials. Afther saving i get a message “succesfully logged in”. But whem i try to add an device the message is ‘no new devices have been found’. I tried several different devices… What am i missing? [edit] Afther saving the credentials i see the message “succesfully logged in”. But in the ‘information log’ i see messages authentication failed? ---

Definitely agree the login is failing, so that does, in theory, mean that either the username or password is incorrect. However, Somfy does occasionally have a temporary issue with authentication. It might be worth updating to the test version as that has had some love given to the login process. ---

When you add /test to the app url Like [https://homey.app/en-gb/app/com.somfy.tahoma/Somfy-TaHoma-&-Connexoon/test/](https://homey.app/en-gb/app/com.somfy.tahoma/Somfy-TaHoma-&-Connexoon/test/) ---

I did not have time to try the test-url, but now the normal app is working! Maybe the restart of the Homey last week solved the issue. ---
