Mesh Radio
Off-grid communication for everyone. Experimental mesh radio platform built on Meshtastic. No towers, no fees, no limits.
How It Works
LoRa mesh nodes running Meshtastic firmware, connected to a gateway that forwards data to MQTT and a web dashboard.
LoRa Mesh Networking
Meshtastic-based mesh nodes communicate over unlicensed 915MHz spectrum. Range varies by terrain and antenna.
Solar + Battery
Nodes use solar panels and 18650 batteries. Runtime depends on transmit interval and solar conditions.
PKI Messaging
Meshtastic PKI allows encrypted direct messages between nodes with known public keys.
MQTT + Dashboard
Gateway nodes forward telemetry to MQTT. Web dashboard displays node status and sensor data.
Encrypted Channels
Meshtastic uses AES-128 encryption for channel messages and PKI for direct messages.
Telemetry & Sensors
Nodes report battery level, GPS position, and connected sensor states at configurable intervals.
Our Hardware
Purpose-built hardware and software for distributed mesh radio networks.
DropLink
Outdoor Meshtastic node
Weatherproof enclosure with solar panel, battery, and LoRa radio. Work in progress.
RAK Gateway
MQTT bridge
RAK WisBlock running Meshtastic with MQTT uplink. Forwards mesh traffic to cloud.
ProxSense
Magnetic sensor board
BsLatch reed switch module for gate/door sensing. Connects to DropLink GPIO.
Current Use Cases
What we're currently testing and developing:
Gate Sensors
BsLatch magnetic sensors detect gate open/close states. Reports via mesh telemetry.
Remote Power Monitoring
Track battery voltage and solar charging status on deployed nodes.
GPS Tracking
Nodes with GPS report position. Displayed on map view in dashboard.
PKI Commands
Send encrypted commands to nodes via Meshtastic PKI. Control relays, query status.
Off-Grid Radio Network
No infrastructure required
Open Source Stack
Built on Meshtastic, MQTT, PostgreSQL, InfluxDB, and Grafana. Dashboard source available on request.
