I recently discovered an unknown device entity (device_tracker.hdb_4540a380) in my device trackers. This device was also added to my personal admin account device list (the ones to track).
I think I read somewhere that iPhones are notorious for changing their MAC addresses when they get a new wifi lease. I’ not sure about that but I just think I remember hearing it.
thanks for your reply. Yes, I was aware about this Wifi Mac address change on iPhones. Therefor i already disabled “private WLAN address” in the wifi settings some months ago for my home Wifi…
Did your recently add a device to your network?
I remember when adding an huawei tablet (just for having an hadashboard, so companion app not installed) it added an device tracker starting with hdb_
My HASS instance is actually accessible from outside my network. So I doubt that it is related to my private network (if someone would have been in my private network I would be able to see this in my logs). I can’t seem to find a known_devices.yaml file. Where exactly would this be located?
hmmm but how would it be possible that this device was assigned to my admin account in HASS? But no I haven’t added any Huawei device to my network (don’t even have one). Would the Home Assistant Cast user be able to do that maybe? (I don’t even know what the purpose of this user exactly is to be honest)
I think, the existence of the file known_devices.yaml depends on the device_trackers, that you use. The file should be top level in the /config/ folder.
what exactly does it say under entities in the column integration?
Is this the ONLY entity from the device or do you have others ending in .hdb_4540a380?
What platforms do you use voor device_tracker: in config?
track_new_devices: true ?
Did u import code from elsewhere to test?
Remember that a lot of devices can autogeneratie a tracker even when not directly connected!
by wifi: all devices once connected to your network (I have I some like this)
BT: My wife’s treadmill, which I have never paired with any device and my wife’s car which was paired with her iphone which was linked in HA.
Virtual: I created a virtual parrot in an emulated android device on my laptop and it showed up too
U could maybe try to add it to a new person and check the map?
btw the cast user is needed for casting to devices (is is generated by the sytem cause it needs admin rights)
it will maybe help you detect if how it was added in HA (and so define which device tracker platform)
U can also look in the known_devices.yaml file and check if mac address really is from an iphone and if it star withc BT_ or not
check all your files for “device_tracker.” (samba share or sth that u can search content of files). this way u can rule out that it is not coming form a coded (binary) sensor.
check your iphone (i am not an ios user) for paired/linked devices
Sadly it didn’t helped. Device just returned unknown if assigned to a new user. Searching for device_tracker didn’t helped neither. I wasn’t able to see any Mac addresses for the connected BT devices on my phone. Maybe on Android this would be possible. I guess i will just remove the suspicious device_tracker and implement VPN on Demand and close for the outside. Thanks a lot for your time and all the suggestions!
