We have this laser scaler:

installed on our BlueROV2, with a Pixhawk, BlueOS 1.1.1, and QGroundControl 4.2.8 for Windows. Is there a way to display the status of the RELAY_PIN parameter in QGroundControl? We can see whether the lasers are on if we’re looking at an object in front of us. However, if we have the lasers pointing straight downwards for seabed surveys and a GoPro on the front of the battery tube, the GoPro obscures the view of the lasers from the BlueROV camera. It would be possible to accidentally turn the lasers off, and we wouldn’t know until we looked at the GoPro footage.
