Unable to repair Zigbee Devices after Migration

Hi there,
I have some Zigbee issues since about half a year now. Within contact with Homey Helpdesk, a realy nice and for all things patient co-worker helpt me out with this thing. I’m like to share this with you.
First make a print of your Homey infra structure. Best thing to do so is from a desktop device. Then make sure that your Zigbeenetwork is first of all setup with wired devices, like Zigbee switches, or lamps. If you have fixed this, then you can add battery devices like sensors or wireles switches or dimmers and so on.
Now you should have build a steady Zigbee network.
Second thing, not unimprtant, there is a maximum number of Zigbee devices that Homey seems to be able to handle. More than about 35 devices will make your Zigbee network instabile. Eventhough that is not a fixed number.
I find that out after I included 9 Frient smokedetectors… If I had knewn this before, I’ve waited a little while to save some money and bought some Z-Wave devices …
Hopefully It may help you to fix the Zigbee-error.

Louis.
