In this YouTube video I show you how I improved my Zigbee network reliability and stability by doing three things
Firstly, I upgraded my old CC2531 based Zigbee USB Coordinator with a newer one based on the CC2652 chipset. This newer chipset supports larger Zigbee networks with more devices, and is better supported by the community.
Secondly, I made sure that my Zigbee network and my 2.4Ghz wireless network didn’t interfere with each other. A lot of people don’t know this, but Zigbee and Wifi both use the 2.4 Ghz radio spectrum. This means that your, or your neighbours, wireless network could prevent your Zigbee devices from talking to each other. Basically, you should make sure that your Zigbee network is using a radio channel that doesn’t overlap with your wireless network channels. More information about this can be found on this fantastic article about Wifi and Zigbee coexistence.
Thirdly, I made sure I created a solid Zigbee mesh network by thinking about where I place my Zigbee router devices and battery powered sensors, and pairing them in a specific order.
