Sorry to hear. My issue was that i count run the update of the Homey - finally I sent it back and bought a new one - now everything works fine
Seems i found the solution now, updated Homey from 12.0.0 to the latest version and now able to install the app. Will try to add the sensors later today to see if everything works.
Was a bit reluctant to updating Homey, as now everything (except Aqara) worked well. Last time I updated was in spring time where the update broke the Zigbee functionality (that was a 2019-unit) totally and took a lot of time with eventually a new Homey unit which has been working well since summer.
