I ran into a similar situation with another device and this work-around worked for me. It may work for you as well:
- Access Homey via the web app (so not the mobile app);
- Go to the device’s settings section (gear icon);
- Change the value of the ‘What’s plugged in’ setting temporarily to something else and save the change;
- Now access Homey via your mobile app and check if you can open the device’s settings without getting the error. If so, then you can change the ‘What’s plugged in’ setting to the original value. If not, well, then unfortunately my suggestion does not work in your case.
