Please realize Homey uses a shared chip for zigbee & Matter-over-Thread.
The Home Assistant community advices to use separate devices for both protocols, to avoid instability and other vague issues. Which is unfortunately not possible with one Pro 23.
The Pro 23 can handle up to 200 zigbee devices, but I’d devide that number in two.
A Hue bridge for instance, has a 50 device limit for a reason. Maybe it can handle more, but that can cause a higher risk of an unstable network.
Very useful zigbee info, to avoid common configuring- and tuning mistakes:
