Question about BenQ ScreenBar Halo

This should work, but I haven't tried it myself (because I only have 1 lamp per location). The manual says:

Pairing and connecting multiple lamps:
You can pair and connect a wireless controller with multiple lamps to operate multiple lamps simultaneously. If the distance between the controller and these lamps is within 1 metre, the lighting patterns of these lamps will change simultaneously.

you have to control them individually, but the automatic function works very well and adapts the lighting to the environment

However, I find that the automatic control works very well. Never control manually.

Unfortunately, you can't pair them.
