LIA is an open-source, Meshtastic-powered pet tracker. No subscriptions, no cell towers, no cloud dependency — just long-range mesh radio, GPS, and hardware you can build, inspect, and repair yourself.
The off-grid device to keep your best friend on track.
Meshtastic Powered
Built on the open Meshtastic firmware and LoRa mesh protocol — no proprietary radio stack.
Beacon Mode LED
Flip the switch to Beacon mode and a bright status LED lights up solid, so you can spot your pet at a glance even in the dark.
GPS Tracking
A dedicated GNSS module reports precise location without relying on cell networks.
Open Source
Full KiCad design, and documentation are all developed in the open under a shared license.
How it works
- 01
Wake
The device wakes from deep sleep on a timer or motion trigger.
- 02
Fix
The GNSS module acquires a position lock.
- 03
Broadcast
Location is sent over LoRa using the Meshtastic protocol.
- 04
Relay
Nearby mesh nodes relay the packet toward a gateway, node by node.
- 05
Sleep
The radio and GPS power down and the device returns to deep sleep.
