Awesome, glad it works well for you!
I just added some fun new features in the recent 1.5 updates. Specifically, each device info page has an interactive map you can pull up and see the tracker history. You can also filter the history by date/time and accuracy. I plan to do more customization to this map and potentially make a custom dashboard card out of it.
Also, main discussion thread for my integration is here for anyone who is interested:
