Damn - had my whole car cargo carrier lifted off my car, so on the hunt for solution for next time.
(seems they snipped the 4 clams hosted on the roof-rack instead of using the key-lock. So much for Thule good qlty products).
Looking at suggestions as I am looking to create a some device (sensor or even GPS tracker) connected via some bluetooth to a car alarm unit (planned to get also) to trigger alerts and car siren.
The idea is to leverage the planned existing car alarm & siren so not too much in carrier above the car. I do prefer a low cost GPS tracker in the carrier as this way I can track the pricks if it happens again (maybe add a 2nd GPS tracker in car too for safety/tracking of car) .
So should I pursue to get some specific alarm that has open interfaces to work with this ‘extra’ wireless bluetooth GPS tracker in carrier and when bluetooth signal is lost from being in carrier to trigger an alarm (issue would be with false alarm if GPS tracker losses power so looking at a long lasting battery option with CAT-M (for GSM SIM) tech but the BT will drain it still. Options here?
If the event does happen, would need the tracking option which I would assume will come from the GPS tracker or service.
That is my idea, more to come but thought would reach out to this community for some suggestions on parts and feedback.
Appreciate any feedback.
