Real Wiimote cursor without sensor bar?

[SassyBassy]

So, today I was playing Wii Music (R64E01) and I connected my first party, Wii MotionPlus INSIDE-Wiimote (keep in mind there was absolutely NO sensor bar anywhere near my PC) and the IR worked, even though it was extremely finicky and would disappear at times it still very much worked, especially after a few minutes of using it, But after switching to Wii Sports Resort (RZTE01) the cursor just disappeared, never to be seen again.

Does anyone have any idea what happened?

There's probably a source of IR light nearby (e.g. some candle, some types of light), hence why it worked but extremely finicky...

Yep, while there weren't any candles in my room, the lights were orange and it seemed to work much better when I light them all up.
