I’ve been diving into the world of Zigbee devices lately, and it’s been quite the journey! 
I’ve got a mix of Zigbee components in my setup, from thermostats to temperature sensors and switches. While it’s been fantastic to see everything working together, there have been some bumps along the way, especially with network stability. Let me share some of my experiences and tips that might help others avoid the same pitfalls.First off, my setup includes a Sonoff Stick as the main coordinator, along with a couple of other routers like the Sonoff and a CC2530 module. The coordinator is situated in the first floor hallway, which seems like a good central location. However, despite this, I’ve noticed that some devices intermittently go offline, even those within sight of the coordinator. It’s been frustrating, but I’ve learned a few things along the way.One thing I’ve discovered is the importance of device placement. Zigbee relies on a mesh network, so having routers strategically placed can make a huge difference. I’ve noticed that some devices automatically connect to the coordinator rather than neighboring routers, which might not always be the most efficient setup. If you’re experiencing connectivity issues, experimenting with device placement or manually assigning preferred connections could help stabilize the network.Another key takeaway is understanding LQI (Link Quality Indicator). A higher LQI means a stronger connection, so ensuring that devices are placed to achieve good LQI values is crucial. I’ve found that moving devices just a few feet can sometimes make a world of difference. Also, avoiding physical obstructions like walls or metal objects can help maintain strong signal integrity.I’ve also learned that firmware updates are essential. Outdated firmware can sometimes lead to unexpected behavior, so keeping all devices up to date is a simple yet effective maintenance step. Additionally, regularly checking the network topology through the Zigbee Alliance tools has been invaluable in identifying weak points in the network.For those struggling with devices that frequently drop offline, I recommend trying a factory reset on both the device and the coordinator. Sometimes, a fresh start can resolve persistent connectivity issues. Also, ensuring that all devices are using the latest firmware versions can help prevent compatibility problems.Lastly, patience is key! Zigbee networks can be finicky, and it might take some trial and error to find the optimal configuration for your setup. Documenting changes and their effects can help you identify patterns and make informed adjustments.If anyone has additional tips or experiences to share, I’d love to hear them! Let’s keep the conversation going and help each other create stable, reliable Zigbee networks.
