There's no actual need to use such a complex and expensive set of apparels. In case of prototyping, it could be even acceptable, but if you're going to production then you should keep in mind some major facts:
- Arduino, despite its simple set of features, is much more energy hungry of other ARM-M0/3 based platforms
- If you adopt ZigBee as transmission medium, then your coordinator node should be wiredly connected to a central networking system, but you haven't any networking on the central Arduino
- Different systems like Bluetooth low energy and/or Wifi could extend your communication range and keep each of your nodes both coordinator or standalone, as any site would share the same set of features of the others.
- ZigBee is by far more expensive of 802.11b/g/n SPI or UART Wi-Fi modules, which can already offer the basic TCP/IP stack and SoftAP features: in practice for any production purposes ZigBee is a nonsense.
Just my two cents, I can propose something low-cost and much more feature proven by integrating a STM32 Value Line product (less than 1.00 USD per 1K pieces.). I can handle the whole project, from schematics to PCB and firmware. I set up the bid just for capturing your attention.
