Hi @guylopes71 , there is currently no custom Zigbee network map, maybe it will appear in the future.
If you have a large area, you need to use Zigbee signal repeater devices for better signal coverage over large areas.
Aqara devices powered by a 220v network (neutral is required) are repeaters (relays with neutral, switches with neutral, motors for 220v curtains, sockets, light bulbs, etc.)
