Auto power off after external power disconnected

[gorzynsk]

It would be great if tracker sends position on external power off and shut downs.

Scenario: install it in a car, autostart on turning the key on. Then after parking send position od turning key off and clean shutdown.

Hi

Do you mean to create a "car" mode that when usb power is provided it turns on and works as usual , and when car turns off (and usb is off) it sends a "power off " beacon and do a clean shutoff procedure?

[gorzynsk]

Yes, exactly.

[richonguzman]

But what would be the difference than using it without 18650 battery and shutting it off when the car is off ?

[gorzynsk]

The difference would be in last report with speed 0 km/h and exact parking spot. czw., 4 sty 2024, 14:42 użytkownik Ricardo Guzman (Richonguzman) < ***@***.***> napisał:

aha! now I get it, you want the last spot to be where you leave the Car/bike

what about just pushing the middle button to force Tx beacon ? or do you want a menu to save it as Last position and turn off automatic?

Are we always talking about T-Beams? as other boards won't allow for "turning off" from software command

[gorzynsk]

Well, if the tracker would send a position at a parking spot automatically I would mount it fixed in the car and react only if a message arrives. I cannot trust myself to push a button each time (-: I'm so absentminded that I forget to take the tracker from my car and it drains battery in my garage. A... and yes - t-beams are most common as trackers here. The ones without GPS and battery are used as digi/i-gate. czw., 4 sty 2024 o 22:13 Ricardo Guzman (Richonguzman) < ***@***.***> napisał(a):

maybe this?

if the tracker have not moved for 15min , it would send a beacon and turn itself off ?

or turn itself off after 3 or 4 not moving positions (at 15 min between beacons)?

[gorzynsk]

Yes, it makes sense. pon., 8 sty 2024 o 11:50 Ricardo Guzman (Richonguzman) < ***@***.***> napisał(a):

So , what you propose:

Add a mode to turn itself off if not moving for 15 min?

[gorzynsk]

Still the best user experience would be to send a beacon after power is removed from USB port and turn off. Of course there may be a way to turn that feature on and off. Best regards Kuba śr., 10 sty 2024 o 13:55 Ricardo Guzman (Richonguzman) < ***@***.***> napisał(a):

Well, nice feature that I was coding on my side here : https://github.com/richonguzman/LoRa_APRS_Tracker/tree/issue_56_auto_power_off

• When board powered via USB : normal operation
• When powered via Battery :
• 1 : if moving, normal operation
• 2 : if standing for X minutes (set in JSON), power off for an amount of time (set in JSON), at wake up reboot etc
• Interrupt when USB is connected to wake up without waiting for the sleep time out

In this case, I can leave the tracker in place, I can check the position of my car without thinking about the battery, switch it on etc

I've just seen that this is the feature I was asking for, so I'll +1 this request and delete mine. Thanks :)
