Here’s my known_devices for my phone:
pi_firstof9:
hide_if_away: false
mac: DE:AD:BE:EF:00:00
name: pi
picture:
track: true
vendor:
This how owntracks tracks on the MQTT, then the SNMP uses this entry for the MAC address (replaced) for my phone once it auto connects to my wifi.
device tracker.yaml:
- platform: owntracks
max_gps_accuracy: 200
- platform: snmp
host: 192.168.1.1
community: rocommunity
baseoid: 1.3.6.1.2.1.4.22.1.2
This blog has details on implementing detection using bayesian filter, I hope someone finds it useful:
@gregg098 I am new to this, so anything you can share on how to set this up would be much appreciated.
So you are saying that I just create my own known_device with a MAC address and then that will be used by Unify. I then keep the one for the App that is already working without the MAC thereby getting two different known_devices for the same device to track on…I think?
First, let all of your device trackers create their own known_devices.yaml entries. The Unifi component will create an entry named after the associated device’s hostname and include the wifi MAC address in it. For these entries, you can rename it if you want to. For example (just randomly picked on):
harmony_downstairs:
hide_if_away: false
icon:
mac: xxxxxxxx
name: Harmony (Downstairs)
picture:
track: true
vendor: Slim Devices, Inc.
To:
bigTV:
hide_if_away: false
icon:
mac: xxxxxxxxxx
name: Harmony (Downstairs)
picture:
track: true
vendor: Slim Devices, Inc.
Now, instead of device_tracker.harmony_downstairs I can use device_tracker.bigtv, if that matters to you.
This works because the MAC address is the identifier. Same goes for the Bluetooth tracker.
Other device tracker components, such as GPS Logger, will make entries that do not have a MAC address. The actual device tracker name is linked to the app so you have to figure out how this is specified in that particular app. Renaming it will break it and Home Assistant will just create a new default entry based on the app input.
GPS Logger entry example:
gregg_phone:
hide_if_away: false
icon:
mac:
name: gregg_phone
picture:
track: true
vendor:
Note, the “name:” field is only the friendly name. It does not affect the device_tracker.xxxx name. I set the GPS Logger app to make the http request with the name of “gregg_phone.”
If you want to group a bunch of trackers, create something like this in your groups.yaml
tracker_gregg:
name: Gregg
view: no
entities:
- device_tracker.gregg_phone
- device_tracker.gregg_phone_wifi
- device_tracker.gregg_phone_BT
Now, the state of group.tracker_gregg is based on the state of all of the trackers. My automations are very simple and just look to see if the state is “home” or not. I have never tried to mess with other zones (e.g. work, school, etc.). The group method may not work if this matters to you.
Hope this is what you are asking for.
Hi All
Just a update to everyone @gregg098 @nickrout @firstof9 @jimpower @oakbrad my effort to combining all the trackers.
After some much testing I setup my first bayesin sensor
binary_sensor:
- platform: bayesian
prior: 0.5
name: 'Victoria Presence'
probability_threshold: 0.9
observations:
- entity_id: 'device_tracker.victoriasiphone_ping'
prob_given_true: 0.9
prob_given_false: 0.1
platform: 'state'
to_state: 'home'
- entity_id: 'device_tracker.victoria_iphone'
prob_given_true: 0.9
prob_given_false: 0.4
platform: 'state'
to_state: 'home'
- entity_id: 'device_tracker.victoriasiphone_2'
prob_given_true: 0.8
prob_given_false: 0.4
platform: 'state'
to_state: 'home'
This gave me a on/off for presence like this:
But I wanted a device_tracker so I found this great Node Red string from https://diyfuturism.com/
I then created this:
You dont have to create this by hand, just paste below code and change your own HA settings/names
(Again thanks to https://diyfuturism.com/ unfortunately the DB is down on this page so I am pasting the code below)
[{“id”:“763070f9.0c571”,“type”:“switch”,“z”:“4056fc4f.0baa64”,“name”:"",“property”:“payload”,“propertyType”:“msg”,“rules”:[{“t”:“eq”,“v”:“on”,“vt”:“str”},{“t”:“eq”,“v”:“off”,“vt”:“str”}],“checkall”:“true”,“outputs”:2,“x”:1316.9999771118164,“y”:301.00000381469727,“wires”:[[“57b903a4.bd2f6c”],[“a080246.03d5ed8”]]},{“id”:“57b903a4.bd2f6c”,“type”:“api-call-service”,“z”:“4056fc4f.0baa64”,“name”:“Set Presence Home”,“server”:“8ac3cd7f.58d3e”,“service_domain”:“device_tracker”,“service”:“see”,“data”:"{“dev_id”:“brad_bayesian”,“location_name”:“home”}",“x”:1510.3333740234375,“y”:272.6667175292969,“wires”:[]},{“id”:“a080246.03d5ed8”,“type”:“api-call-service”,“z”:“4056fc4f.0baa64”,“name”:“Set Presence Not Home”,“server”:“8ac3cd7f.58d3e”,“service_domain”:“device_tracker”,“service”:“see”,“data”:"{“dev_id”:“brad_bayesian”,“location_name”:“not_home”}",“x”:1520.3333282470703,“y”:335.99999380111694,“wires”:[]},{“id”:“afb02bc5.351e68”,“type”:“comment”,“z”:“4056fc4f.0baa64”,“name”:“Convert Bayesian Sensor into Device Tracker”,“info”:"",“x”:1015.0000381469727,“y”:252.00008296966553,“wires”:[]},{“id”:“a86ac3f0.00c67”,“type”:“inject”,“z”:“4056fc4f.0baa64”,“name”:"",“topic”:"",“payload”:"",“payloadType”:“date”,“repeat”:“10”,“crontab”:"",“once”:false,“x”:942.3333129882812,“y”:300.6665403842926,“wires”:[[“d43007ca.720b78”]]},{“id”:“d43007ca.720b78”,“type”:“api-current-state”,“z”:“4056fc4f.0baa64”,“name”:“Bayesian Presence”,“server”:“8ac3cd7f.58d3e”,“halt_if”:"",“entity_id”:“binary_sensor.bayesian_presence”,“x”:1142.3333892822266,“y”:300.66639733314514,“wires”:[[“763070f9.0c571”]]},{“id”:“8ac3cd7f.58d3e”,“type”:“server”,“z”:"",“name”:“Home Assistant”,“url”:“http://HASSIP:8123”,“pass”:“XXX”}]
Then I finally get my normal icon but its based on all my sensors from my bayesin setup
That is based on
SO IS THIS PERFECT? NO! but it’s getting to a point where its better than anything I had before 
UPDATE: I got the Home detection to be within seconds and no false positives!
The leaving home is now taking 7 min before registering but its stable, so I think I have to live with that
Cheers
