I just installed one of these a couple of days ago. They come defaulted to Exhaust Fan (On/Off) Mode. I decided to use the quick tap sequence to change it to Ceiling Fan (3-Speed) Mode. I followed the instructions to hold down on the bottom part of the paddle (off) while simultaneously tapping the configuration button three times. The LED bar flashed solid orange, indicating it was updated to 3-Speed mode.
It did not operate in 3-Speed mode. It was still behaving as an On/Off switch.
It was only after I went into the parameters in Zigbee2MQTT and changed it to 3-Speed mode that it actually changed to 3-Speed mode.
Not a problem for me since I got it to operate in 3-Speed as desired. Just letting you know that the quick tap sequence did not work even though the LED indicator confirmed that it did.
