i upgraded from a PI3 to a PI4 with an SSD. I used a full back to get the PI 4 running. Everything is working except for my Zigbee motion sensors. I’m using a USB stick and the door sensors are working. They are all Aqara sensors. Have tried rebooting and even tried to install a new sensor with it being a few inches away from the USB stick. I’m running core-2021.9.7, the same as was on my PI3. I’m out of ides, thx.
I have a cc2531.
Do i need a new Dongle?
Depends on your case. I have the same dongle and its working for 20 x devices (ubuntu supervised).
Try re-pairing those sensors.
I have and they don’t repair. Pulse it will not pair with a new Aqara Temp sensor. O they are all Aqara Motion sensors.
Do you use an USB extension cable ? Pi4 with SSD has a lot of interference from the USB3 ports.
No but I have one on order. How long should it be?
I use one of 1 meter, but as long as it is away from your pi it should be OK.
