Regardless of Zigbee application/setup recommend reading and follow these general tips → Generic best practice tips on improving Zigbee network range and general stability · zigpy/zigpy Wiki · GitHub
Same advice in ZHA integration documentation, CC2530/CC2531 do not support Zigbee 3.0 devices because they have old obsolete hardware and outdated end-of-life firmware so are no longer recommended → https://www.home-assistant.io/integrations/zha#known-working-zigbee-radio-modules
- CC2530/CC2531 USB stick, module, or dev board hardware flashed with Z-Stack coordinator firmware (no longer recommended as uses deprecated hardware and very old end-of-life firmware (because Texas Instruments stopped maintaining the SDK software development kit for it since several years back), plus will not work properly at all if the whole Zigbee network has more than 15-20 devices)

Suggest just buy the CC2652P-based ITead’s “Sonoff Zigbee 3.0 USB Dongle Plus” (model “ZBDongle-P”) based on Texas Instruments CC2652P +20dBm radio MCU now sold for $19.99
