This is a device that can plug into a cigarette lighter plug, and you can use it like you would OnStar. It has a cellular connection; you can talk to somebody for various needs, etc...AND you can track it's location via webapp.
It has an internal battery if it gets unplugged.

I was thinking for the security of a trailer, you can run a 12V line and just hide it WITHIN the wall or in a difficult-to-find nook.
What are your thoughts?
Ideally, I would also like the ability to monitor conditions like indoor temperature, battery, etc. Does anyone know of better devices at a cheaper cost--short of building my own with a Raspberry Pi/Cellular PiHat
