Sorry, I may have been unclear in my response.
The zigbee meshing in Homey isn’t working “correctly” may have been a better statement. 
To check the mesh you can always look at http://developer.athom.com/tools/zigbee
The mesh-map there should show you the routes that each device has/takes. And if you don’t see anything except them doing a direct connect to Homey, or that the route a unit takes is illogical, well the mesh isn’t working. It may take some time to get the full map and/or time for the mesh to rebuild (in case you added something recently).
You can search and get a lot of information on this, with many people having the same issues. But for reference, you can look at Zigbee meshing screwed up
