I am using a Sonoff Dongle USB Zigbee that i use to communicate with two Aqara temperature and humidity sensor.
Until yesterday afternoon everything went right and suddenly the communication is not stable:
as you can see before that spike everything was good.
I’ve also tried to buy a new sensor and the problem is still there.
Can be the usb dongle?
I’ve already resetted and change usb port.
From system log i have:
