Please update System/Control to also 'Shut Down' #179

Open ImagineerNL opened 1 year ago

ImagineerNL commented 1 year ago

Currently $/System/Control=RESTART restarts the controller.

System/Control | ESP444 | Admin | RESTART | Restart the Grbl controller. Requires value = RESTART

I seem to have to do this a lot of times immediately after a power-on. This might be because of shutting down through a powercut is not great. If we could power off with $System/Control=SHUTDOWN , we can add it in a macro for the system to do a clean powerdown, after which it is safe to cut the power.

I can weigh in here. Technically, the only way to power down an ESP32 board is with a power switch. However, it does have a couple sleep related modes that might be of interest.

Here's an example of how we could implement this. As noted in the video comments, I would release this with a deep sleep interval of like a year so the only way to get the board to respond would be by physically powering it off and disconnecting its USB connection / powering off the device connected to its USB port. You could always just hit the reset button too.
