Hi Wlt3r,

Bummer. FYI KaKu devices only can interfere when they send/receive data at exactly the same moment.  
They shouldn’t operate on the same channel though.

Yesterday I"ve read about disappearing apps, maybe the KaKu app has similar issues.

Today I got flows with gray cards (most) as well, also disappearing flows and appearing flows without touching anything.

Please make sure to install version 3.49.2 from the [store](https://homey.app/a/cloud.shelly/) as that seems to fix the issue for the people that have responded to us already. Note that it is exactly the same as 3.49.1, it is just a rebuild with an incremented version number, making a file corruption of some sort the most likely culprit.
