How to turn DVL A50 off automatically when the ROV is brought out of water

General Discussion

Hi. Is there a way to turn off the DVL A50 automatically when the ROV is brought out of water? I need the DVL to turn off automatically once it is detected that the ROV is out of water or else the DVL will get damaged if it continues to remain on while it’s out of water.

Hi @rai ,

I faced this issue, too. We should be able to get something done with a relay (I just used a TIP122 instead) to cut power to it whenever the ROV is unarmed, or something like that. I think a lua script be easy and handy for this case.

@wlkh Is there a way to do a “soft” shutdown through the API? that would be even better as we could get it built into the DVL extension.

I would like revive this or put another vote towards implementing this

It seems there’s (now?) an acoustic_enabled option in the API, which should effectively serve this purpose (along with dark_mode_enabled if you want to also turn off the device’s status LED).

Is that configuration already provided via the DVL’s own interface (that’s exposed at the bottom of the Extension’s interface page)? If not we should add explicit support to it in the Extension interface.
