Sonoff zigbee 3.0 usb dongle plus vs conbee 2

Hiya all,

just a quick one if anyone can please comments on which one is best to go with?
my kits are generally, aqara and ikea. I’m interested in getting frytur blinds and I heard it works “okay” with conbee. have not heard anyone’s experience on using sonoff with frytur.

thanks

I think the Sonoff is a newer version of Zigbee. I was deciding between the two and went with the Sonoff. So far I’m just using some IKEA bulbs. It’s suggested to update the firmware on the Sonoff dongle. I found a difficult to follow guide but managed to figure it out using Terminal on a Mac.

is that with tasmota? or you just used the stock firmware?

Stock firmware is an older version of the Zigbee2MQTT firmware. It is easy (and advised) to upgrade to the newest Zigbee2MQTT Firmware.

I have Raspbee II and my raspberryPi 4 has an aluminum alloy case, so I soldered an external antenna to Raspbee II - signal quality was 220-255lqi. I connected a USB 3 SSD and had to move zigbee antenna away from it to get rid off radio noise. So now I have Sonoff Zigbee 3.o USB dongle and signal quality is 100 and may be N/A very often. I am very disappointed with the purchase of Sonoff Zigbee 3 USB. And a purchase I’m considering is Conbee II. Or can anyone advise me sothething better?

Is it possible to upgrade sonoff zigbee 3 under linux ?

Do you made a choice already?
I have both sticks at home. Always used the conbee ii without any problems.
Recently I bought a sonoff just to try. Flashed new firmware and already had some problems.
Sometimes, if I restart HA I need to remove the antenna of the stick because otherwise it won’t start up somehow and it’s giving me an error. Maybe I go back to conbee later but I’m still in my trial period. Haven’t had any different reactions from lamps or sometinf till now

Does this mean I have to use Zigbee2MQTT as my broker or can I use ZHA?

No, ZHA is fine.

More precisely, Sonoff uses an older version of the firmware built by the z2m developer. The firmware itself is not z2m specific.

When you reboot HA do you have any Zigbee devices drop?

No, I do not.
