400S-P Support

[finishthepint]

I’m curious if anyone has tried the 400S-P with the “PlasmaPro” feature. Curious what features are supported besides the newer Plasma button.

You mean this one:

=> looks very similar to 400S, the protocol will be slightly different for the extra button/indicator for Plasma/Pro
should be an extra value in response and a new command.

I would need good protocol dumps from such a unit; with them, it is only very little work to add this device.
