Is my car home? - Geofence

What's the preferred Indigo Geofence solution? I'd like to check to see if my car is not in the garage (and not moving) to lock the doors if they aren't locked. I have lat / long - how do I Indigo Geofence ?

when the car is far enough away ( distance to house > accuracy of car position ) you could do a simple trigger. if it is parked in front of the garage its likely not precise enough.

there you could add a proximity sensor inside the garage looking at the garage door:
if dict > 5 m garage door is open
if dist > 10m car is not in front of garage.

there are several proximity sensor solution you can use that can go to 20+m.
in addition there is a rotating proximity sensor (lidar) that gives you a complete view of any object in 360d. They can go up to 50 meter.
they can give
door is closed
car shaped object is in the garage
car shaped object is outside the garage .. half way in ..
I tried that one with pibeacon and the lidar sensor and that works. Reaction time is < 1 secs and pretty accurate. you actually id the front part of the car.

This won't work in my garage. Kids int he neighborhood play in the garage.

The lidar can distinguish between a person and a car. And if there is movement and how big the object is and direction too: left / right / towards / away

It takes 2-10 snapshots per second and > 400 points( directions ) = resolution is better than 1 degree.

Pressure mat sensor?

Does your car have Wi-Fi and do you have UniFi AP’s? Karl UniFi plugin detects BMW wifi easily when car is closeby!

I can try that but it won't work when the car isn't on. I found a solution, now trying to figure out how to run Python 3.8 in indigo

... and pibeacon has a car device model

It needs
1 beacon in USB port
1 aaa battery powered beacon in car
1 beacon on each key chain( up to 3)

With these beacons it can determine motor on/off: car present/ away and from the time sequence of events:

each car devices has the dev state:
Home motor off
Home motor on
Leaving
Left
Arriving
Home motor on
Home motor off

Hi (putting this out there for completeness)

Another option is using AI image recognition to change action run.

With BlueIris and Deepstack plugin, this is standard usage.

Admittedly do need Camera covering Garage (I have a couple in mine)

Some trigger eg. Motion triggered -> Deepstack plugin check for Car -> Yes or No -> different action groups run depending on result. Additionally could check for person present

Works really well, also covers any car rather than just one car..,.

I wound up using a Python geofence to check if my car is inside the fence. The BMW Connected plug-in return lat long every few minutes.

But, with the AI image recognition, could I tell whether my Alarm is armed (red vs green indicator light) ?

Hi,

Something that simple probably doesn’t need AI. Although could train it for anything.

Just a snapshot of current camera image and Color of a certain pixel? Python Pillow image library I’m sure would do this. Issue may be red/green may change position? In which case could probably do a broad box with - is there green within?

Something like
From:
https://stackoverflow.com/questions/110 ... -using-pil

Code: Select all

im = Image.open('image.gif')
rgb_im = im.convert('RGB')
r, g, b = rgb_im.getpixel((1, 1))
print(r, g, b)
(65, 100, 137)


& for rectangle just set up a x and y loop checking every pixel.

I think I could use that.

By the way, this was my solution: It takes lat , long as inputs

Code: Select all

#!/usr/bin/python3
from shapely.geometry import Point, Polygon
import sys


def main():
    coords = [
        (39.008234937234256, -77.37684452531161),
        (39.00809324520176, -77.37627518191934),
        (39.00733602026089, -77.37671994280922),
        (39.0076547326009, -77.37724949835487)
    ]
    homeFence = Polygon(coords)

    arglat = float(sys.argv[1])
    arglong = float(sys.argv[2]) 

    bmw = Point(arglat, arglong)

    print("{}".format(bmw.within(homeFence)), file = sys.stdout)


if __name__ == "__main__":
    main()
