That’s normal for Zigbee — you can connect up to around 50 devices reliably. You can add more, but in my experience, problems start to occur when I go beyond that. At first, it might work for a few days, or even weeks, but eventually devices start disconnecting.
Now, I keep the limit at 50 devices, and everything works fine. Also, make sure to connect your Zigbee routers first, then add the end devices — that makes a big difference.
If you need to go beyond 50 devices, consider using Z-Wave as well, or setting up a Homey Pro on each floor. That way, you can have up to 50 Zigbee devices per floor, and it stays much more stable.
