How to create access point in zigbee?

I am using 3 wireless temperature sensor:

  • 1 in garage
  • 2nd in 1st floor of corporate building store area
  • last one on Top floor of the building in another store area.

I have learnt about wireless mesh network but need suggestion create one with zigbee devices.

Like ESP8266 I am not able to find any sample for zigbee to create the access points or station in embedded C

Any leads on this will be a great help.
