Need to extend zigbee range for reach aqara sensors

Can someone suggest me a more reliable way to extend the range of my Zigbee network to integrate a bunch of Aqara temperature sensor.
The coordinator is a sonoff zibee 3 with custom firmware, I tried to use the same hardware flashed as a repeater but aqara seems to refuse to connect to it.
thank you

You could try the Ikea repeaters (router), they are cheap and seem to work nicely in a concrete building were i had issues. Besides that, any Zigbee device that stays powered on like a switchable socket can act like a router. Just check the specs if it will do that.

2 thing to keep in mind tho:

  1. Make sure you install them where the signal is good from the coordinator or another router.
    You can check your signal map in Zigbee2MQTT for that or other ways.
  2. Aqara and some others will sometime not use the router but will connect to the coordinator even if it has a very low signal. Best bet is to pair them at their actual location so you have the best change they will work though the router.
