Problems with SONOFF Zigbee Dongle Plus e

So, I’m new in this zigbee coordenators and I’m having real problems with my network and making all work out perfect.

I have a SONOFF Zigbee Dongle Plus V2 (the ezsp version adapter) and I have loads of problems with it. I can’t understand why, but all the devices I have won’t be working for more then 6 hours until they appear to be connected but don’t work. I’ve tryed ZHA and now I’m trying Zigbee2MQTT and it’s the same deal. All devices are online but won’t register any activity after some time.

Can anyone have any idea how can I solve this?
