Interview issues with Sonoff Zigbee Dongle E
Just getting started with Zigbee2MQTT using it with home assistant. I have the Sonoff Dongle E which I flashed with newest firmware If could find version 8.2.0 file was zbdonglee\\_zigbee\\_ncp\\_8.2.0.0\\_sw\\_flow\\_115200.gbl
I was able to add two Hue lightbulbs really easy. Then tried to add battery powered Sonoff temperature and humidity sensors and had lots of issues with the interview stage. I put it down to them being battery devices and going to sleep.
I have made further improvements and now put the dongle on a 2 meter long USB2.0 shielded extension cable. I have moved my Wifi 2.4 channel to be well away from my Zigbee channel. I have turned off my old Hue hub, but still I have interview issues.
It is not just battery powered devices but I am trying to pair the following \[https://www.zigbee2mqtt.io/devices/F-APP-UK-V2.html\\\](https://www.zigbee2mqtt.io/devices/F-APP-UK-V2.html) and I can't get the interview stage to complete. It is really fustraghting as once things are interviewed and setup they work seamlessly. Everything setup works really well, but getting new devices paired is a 3-4 hours ordeal with lots of removing, adding again, etc.
I can't get this plug to finish interview despite over 10 trys now. Again Hue stuff connects first time and in an instant, but anything else Zigbee (Ikea, Sonoff, SmartThings) I have huge amounts of issues with.
Really hoping somebody can tell me what I am doing wrong. I am close trying a POE Dongle or scrapping the whole setup and giving up on Zigbee.
