Suggest you instead read and follow these first:
- Blueprints for getting double press, triple press, long press commans, etc. to work with ZHA:
- https://community.home-assistant.io/t/guide-for-zigbee-interference-avoidance-and-network-range-coverage-optimization/515752
- https://www.home-assistant.io/integrations/zha#how-to-add-support-for-new-and-unsupported-devices
You can have several Zigbee Coordinators/hubs/gatways/bridges to Home Assistant but you can not have several Zigbee Coordinator’s on the same Zigbee network or a device to more than one Zigbee Coordinator/network, so the Zigbee Coordinators/networks will not know about each other. Read the ZHA docs (especially the instruction and limitations sections) → Zigbee Home Automation - Home Assistant
