I paired a new remote with a WiiM Mini this morning; it worked fine. I didn't see that LED illuminate at all, either during pairing or while using the remote to change volume, pause or restart playback, etc.
I'm frankly not sure what the LED is for, but it wasn't involved in my pairing... The
WiiM Remote manual doesn't even mention the LED; it's visible on the cover page, but doesn't show on the picture in section "4. Controls" and isn't mentioned. So perhaps it's a work in progress that isn't being used yet(?)
The steps I followed were:
- press the input selector and mute buttons on the remote for several seconds (which gave no feedback -- no LED blink, no beeps, etc.)
- went into the WiiM Home app, opened settings for the WiiM Mini I wanted to control with the app, tapped the Remote option, followed prompts
- got confirmation message in the app
It went smoothly for me, but didn't involved the LED...
