piBeacon:15- device type CAR

[kw123]

starting with v 7-37-37 the plugin supports a device type = CAR

1. create a device plugin = pibeacon, type = CAR, eg Volvo or Moms car ...
2. select
(A) a battery type beacon (i.e. with AAA battery), place that beacon in the CAR (fixed)
(B) a USB powered beacon put into USB output in CAR
(C) 0-3 beacons attached to your car keys (eg xy)

The CAR device will have 3 states with the following values:
(a) LOCATION= HOME/ AWAY
(b) ENGINE = ON/OFF/""
(c) MOVING = STOP/LEAVING/LEFT/ARRIVING

Conditions for the states:
LOCATION:
-HOME: if Beacons A or B or all C are UP (at least one of the beacon is how so the car must be home)
-AWAY: if Beacons A and B and one of C are down (none of the beacons is home)

ENGINE:
ON if beacon B is on
OFF if beacon B is off
"" if STATUS =AWAY

Moving:
- STOP if home and Beacon B = off (HOME and car is off = must be home standing)
- LEAVING if HOME and Beacon B = ON ( car is home and battery beacon or key is on and USB key comes on. = home starting engine --> must be leaving)
- LEFT if AWAY (no beacon visible so car must be gone)
- ARRIVING if AWAY and any beacon on (was away, have detected at least one beacon so it must come home)


the state "status can be set to show either one or 2/3 of the states described above.

This can be used to detect your CAR(s) home/ away, coming home, leaving ..

It utilizes "fastDown" option for the beacons: if a beacon does not send a signal for x seconds the RPI will send a "fastDown" message to the plugin. for the status to go down ALL RPI must send the fastDown signal.
This is in contrast to not sending anything to the plugin and the plugin will set the beacon status to Down after seconds expiration time.
This will allow a faster reaction time. The fastDownTime used here is 15 seconds. You can manually adjust it for each beacon in beacon device edit. Increase if you have just one RPI, or you could go down to 10 seconds if you have 10 beacons. But you might get some false positives.

One item i need to improve:
sequence of beacon coming on/ off line. They might be just a second apart: eg
battery beacon comes online first then the USB that would result in a state HOEM, then "leaving" not "arriving" the other way around would it work fine..

Need to add short timers and controls to make sure that these things are handled correctly.

In other words not just current state but also last state has to be taken into account.

will take a day or so.

posted v 7-37-40.
improved the flow and timing of the states, added state indicators etc to the layout. And have removed the "beta"

This is how the data looks when leaving and when arriving

Code: Select all

 id  |             ts             | engine |  motion  |      status          | location 
-----+----------------------------+--------+----------+----------------------+----------
 134 | 2017-01-16 21:46:35.244983 | off    | stop     | home/off/stop        | 
 135 | 2017-01-17 14:03:49.225078 | on     | leaving  | home/on/leaving      | 
 136 | 2017-01-17 14:04:35.525524 |        | left     | away//left           | away
 137 | 2017-01-17 15:01:56.764415 | off    | arriving | home/off/arriving    | home
 138 | 2017-01-17 15:01:56.939498 | on     |          | home/on/arriving     | 
 139 | 2017-01-17 15:02:39.540619 | off    | stop     | home/off/stop        |

Hi Karl, Which USB beacons work for (B)? I have a ZUS that lives in the car and is charged on USB, but as it has a battery that is recharged, I am not sure it will change behaviour with engine on or off?

Thanks
simon.

you need one w/o battery to detect motor on/off and put it into a usb port that switches of when the keys are out.

do menu/basic setup help.
it gives you an overview of ... and beacons tested and ... ( several pages)

the feasy USB has an antenna ~ 3time distance reach, and the simplest is the radius USB beacon for that purpose.

This plugin just gets better and better. Got a feasy USB beacon and a feasy white triangle now in the car (Zus been repurposed) and this works great.

[kw123]

I use one if the beacons that come with 3 /4 aaa batteries- instead of the feasy triangle. Those beacons last for MANY years (>4 right now, still plenty of juice left)
Though they are large
The signal strength is the same though
Karl
Is and thanks for the nice feedback. Feels good

I couldn’t find one of those in UK Amazon. Will look harder.

[kw123]

I bought one from a Uk dealer Beaconzone

Cheers. They say they only supply to businesses

And you can try

RadBeacon E4

Also do menu print help.
That gives you a list of tested beacons w battery size
