This is an ongoing issue, for which there have been / are lots of threads already.

The summary is:

It uses something called locationsharing lib, that uses undocumented methods to retrieve data from Google. The account needs to authenticate and Google keep changing how. In most cases the authentication now won’t work. The error you’re getting is because of that.

On this thread you can find into about a tool that might help, it helped me but others have had no joy.

completed another pretty big refactor on my ground up rewrite of the google_maps location sharing platform.

  • it works
  • cookies? what cookies. we don’t need no stinkin’ cookies. how you call fixing an application by making the user manually create the cookie file with a command line script is beyond me. the f is that s?
  • designed to work explicitly with 2FA via device auth. if you don’t have 2FA of some sort set up on the account you’re sharing location info with in the first place, please don’t have children.
  • tons of debugging options for quick down the line resolution!
  • geohash output for all the grafana graphing goodness!


this is still a work in progress. if you’re not running docker or a manual install and aren’t comfortable taking the content and modifying it to suit your needs…good luck.



Looks good, but can it works with hassio install ?
