By import I mean "automatic sync", yes.
I just use it to "track" myself. You can use it for geofencing, yes. You just attach it to your user and it adds your location to you.
The main reason I use it over the Home Assistant app's built-in sensors is that PhoneTrack is able to store your location data if you're offline (out of cell network range, etc.) whereas the HA app just discards it.
It's been rock solid for over three years for me.
I'm running PhoneTrack which has a Nextcloud component. The data can be imported into HomeAssistant and also Prometheus.
Setup Matrix and add a bridge for Discord.
Install powertop. It will allow you to tune the power consumption.
Take a look at this page for someone explaining how they moved from using Discord directly to using it via Matrix.
One of the "powers" of OSS is that the license usually required changes to be fed back upstream.
If Meta were not to do that the authors of Lemmy could ask someone like EFF to take legal proceeding against them.
Install some bridges. I've managed to remove all those third party chat apps from my devices and just use Matrix to chat to everyone whether they're on Slack, Discord, WhatsApp, IRC, etc.
They don't, really, but they could mention the repeated, annoying message pop-up to someone who can make a difference and get it sorted out.
I really don't like Meta but we should encourage the use of open protocols, regardless of who uses them.
I bridge WhatsApp, Telegram, Signal and Slack using Matrix.
Works extremely well for me.
I'm using PhoneTrack with NextCloud for 24x7 tracking just like Google History.
You just start an activity and just leave it going. It syncs to NextCloud "live".
Battery drain is minimal (much like, say, WireGuard VPN).
