Hi! Any ideas? This is a very old topic. I have the same situation
It was stable for years, but now it crashes several times a day.
No error message, stops at random times.
Sonoff Zigbee BR (EZSP)

Highly recommend buy a Zigbee USB dongle instead and connect it via a long USB extension cable. Remote WiFi adapters are not recommended, and especially not for for EZSP.
