The sensors don&rsquo;t cover the full area up to the door, which sometimes delays activating the night light (LED strips under the bed) when someone walks into the bedroom. As I said, not satisfying.</p> <p>So far, I have two Aqara Motion Sensor P1 sensors installed, but I want to move away from Aqara. I grabbed a IKEA TRÅDFRI (E1745) from the shelf, and added the batteries. Pairing the device with Home Assistant (HA) was easy. Updating the firmware on the device was more work. But it was necessary, because the motion sensor with the old firmware did not reliably report motions in HA.</p>
