fallen storm
Hi, my first post and seeking some help....
I'm using Z2m for my Zigbee devices. I've been running HA with Z2m somewhat successfully for about 6 months increasing the number of devices under control over time. Along the way I also upgraded my zigbee controller to a SMLight SLZB-06P10 as I wanted a PoE solution. I recently crossed the 50 devices mark and around that time, the stability of my network has dropped away.
Every few days, at seemingly random times, Z2m loses connection with the controller and stops working.
I get this error when I attempt to restart z2m;
"error: z2m: Error: Failed to connect to the adapter (Error: SRSP - SYS - ping after 6000ms)
at ZStackAdapter.start (/app/node_modules/.pnpm/zigbee-herdsman@3.2.1/node_modules/zigbee-herdsman/src/adapter/z-stack/adapter/zStackAdapter.ts:113:27)
at Controller.start (/app/node_modules/.pnpm/zigbee-herdsman@3.2.1/node_modules/zigbee-herdsman/src/controller/controller.ts:136:29)
at Zigbee.start (/app/lib/zigbee.ts:69:27)
at Controller.start (/app/lib/controller.ts:142:13)
at start (/app/index.js:161:5)"
I have the controller on a static IP set on my router (late model eero). The controller is a distance away from my wifi router.
I've worked out that if I restart both the controller and my router, and then restart Z2m eventually it establishes connection without any channel or ID changes.
Whilst I've been using HA for about 6 months, I'm still learning quite a lot so need some guidance on what maybe causing the instability and how to better diagnose what may be going on. Not sure if it relates to the number of devices I now have or a network problem I'm not seeing or a rogue device or whatever.
Appreciate any assistance.
