Homey Zigbee - limit of 20 battery powered devices

OK, I’m curious to see if that has any effect. A good way to test how your zigbee mesh is set up, is checking https://developer.athom.com/
You’ll have to wait a minute, as the mesh-network needs to load in order to show on your screen. You’ll see something like this. This is a screenshot of (a part of) my zigbee mesh.


The developer site shows which devices are a router or an endpoint. It also shows the route, based on the little coloured blocks with the number inside.
