custom_components.zip worked for me, but I didn’t unpacked it to /config/custom_components/device_tracker/__pycache___/ directory as the *.pyc files, just unzipped all to /config/custom_components/device_tracker/ and that’s it.
but I’ve got another question:
devices found by google maps are added to known_devices.yaml as google_maps_<21-numbers-long-id>, and following that, I need to use it as device_tracker.google_maps_<21-numbers-long-id> in my automations. is there any way to make an alias so automations/scripts could “see” it as for example: device_tracker.wife_google_maps_location?
I tried adding the “name” attribute but it isn’t working unfortunately.
