I recently purchased two SmartThings Plugs, primarily to use them as range extenders, for Aqara Sensors. I'm using a Raspberry Pi 4B computer, with a Raspbee II - to link with my Zigbee devices. I have set them to Zigbee Channel 25. All of the devices link to the Raspbee II, including the SmartThings Plugs. However, the plugs do not appear to be extending the range of the Zigbee Aqara sensors, even though both plugs and sensors are paired with the Raspbee II, on Channel 25.
Is there something else, which I need to do; to get the plugs to repeat the Aqara (Zigbee) sensors?
