I’ve been working on optimizing my Zigbee energy sensors to reduce unnecessary readings and improve network stability. After setting up Z2M with a Sonoff USB Dongle-E as my coordinator, I noticed that the sensors were reporting data too frequently—about once every 3 seconds—which was overwhelming the network and causing instability after a day or two.
To address this, I’ve been experimenting with adjusting the sensor settings. While I haven’t found a direct way to change the reading interval within Z2M, I’ve discovered that some sensors allow configuration through their manufacturer’s mobile app. For my Zemismart SPM01 sensor, I was able to extend the reporting interval to 10 seconds, which has significantly reduced network congestion.
Another approach I’ve taken is monitoring the network performance using Z2M’s built-in tools. By keeping an eye on the network health dashboard, I can identify when sensors start behaving erratically and take proactive measures, like temporarily disabling less critical devices or restarting the coordinator if needed.
I’d love to hear from others who have tackled similar issues. Have you found effective ways to manage sensor frequency or improve network stability? Any tips or tricks would be greatly appreciated!
