"storage"/"Off" mode

[blaueente]

Is there any possibility to turn it "off", i.e. in a state where it deactivates anything it can, to save most power it can, such that it can only be woken by (long-)pressing the button, and then it boots again?

This nicely overlaps with #101, as I mentioned there... would be great to see reboot and power off (halt CPU) facilty ;)

It's not possible to completely cut the power, as there is no hardware reset or power off button on the device. However, it might be possible to halt the CPU, but ensure that it's configured correctly to reset on a push on the button.

A mode where we disable everything (ble, sensors,...) and where the system task run as slowly as possible (but fast enough to refresh the watchdog) is indeed possible.

Agreed, this is also important to me, since I need to turn my unit off on a weekly basis, as well as before some of my religion's holidays, to conserve battery, since I cannot use it for religious reasons.

I wonder if we should be extending the long press (7 second) action to popup a menu instead of just hard reset the way it currently is. This could implement this and #101 at the same time.

[JF002]

The long press is directly connected to the watchdog : the watchdog is not refreshed as long as the button is pressed. This ensure that there's very little chance of a bug on the watchdog handling and that the user will be able to reset the watch in most cases. IIRC, the watchdog is already set to the highest value, so we won't be able to increase the timeout.
However, it should be possible to display the popup a bit sooner (3-4s ?) so that we can display info to the user before the watchdog resets the watch.

@geekbozu Also a power state, as @JF002 had mentioned it's possible, could be labeled as "Poweroff", or"Hibernate", or something that better describes it.

#480 can already open separate apps on button double click, long press 400ms and longer press 2000ms. The last one was added for a power menu or similar.

Perfect Ill give that PR a review soon so if its ready we can get it merged so we can build on it! Awesome work like always riksu!
