AFAIK, the Bridge has the same Zigbee controller hardware as Homey Pro.
That should be good enough / proven technology.
Yes, because Homey’s Zigbee is known to be very stable and without limits 
I also had zigbee problems a few weeks ago , i couldn’t add new devices .
Support can reset your zigbee, you can’t do This yourself.
After they reset my zigbee netwerk adding devices worked again.
All your zwave of rf … Devices keep on working.
