Thank you for the reply. I managed to get it working with Bluetooth, that was not the issue.

I believe it was due to these lights being brand new, and seemingly a newer iteration, or at least a different version.

I had to use the --read-input-forever of hidapitester to monitor the hex values being passed when I manually turned the lights off and on, to work out the required hex values to pass.

In case it helps anyone else:

To Turn the RGB lights ON:

Set-HIDAPItester -vidpid $vidpid -usagePage ff43 -OpenPath $OpenPath -output "0x11,0xFF,0x0A,0x4E,0x01" -HIDAPItesterPath $HIDAPItesterPath

To Turn the RGB lights OFF:

Set-HIDAPItester -vidpid $vidpid -usagePage ff43 -OpenPath $OpenPath -output "0x11,0xFF,0x0A,0x4E,0x00" -HIDAPItesterPath $HIDAPItesterPath

To Turn the White lights ON:

Set-HIDAPItester -vidpid $vidpid -usagePage ff43 -OpenPath $OpenPath -output "0x11,0xFF,0x06,0x1E,0x01" -HIDAPItesterPath $HIDAPItesterPath

To Turn the White lights OFF:

Set-HIDAPItester -vidpid $vidpid -usagePage ff43 -OpenPath $OpenPath -output "0x11,0xFF,0x06,0x1E,0x00" -HIDAPItesterPath $HIDAPItesterPath

Thanks for sharing your results! Le mar. 19 déc. 2023, 13 h 38, Tim Maiden ***@***.***> a écrit :
