- Which sonoff zigbee stick? I believe sonoff has 2 (or 3?) now. And have you updated the firmware of the sonoff stick?
- Also which Tradfri devices? I mean was it the battery in the control buttons or in the shades (or both, or something else)?
Oh and have you updated the firmware of those Tradfri devices? - Also was that ZHA or zigbee2mqtt (or something else) in your setup? This does make a difference when it comes to Tradfri, it seems.
I am interested in this similar setup, and recent reports in this forum indicated good results from the combination of sonoff zigbee usb dongle plus + Tradfri shortcut botton + zigbee2mqtt.
… Hence the ask.
