Hardware
Purpose-built nodes for off-grid monitoring. Solar-powered, weatherproof, and designed for the field.
Working
DropLink
Solar-powered outdoor node
Weatherproof mesh node for gate monitoring, relay control, and remote environmental sensing.
- Weatherproof enclosure
- Solar + 3000mAh battery
- RAK4630 radio
- GPIO breakout
Working
RAK Gateway
Bridge mesh to cloud
Connects your mesh network to the internet so all node data flows to the dashboard.
- WiFi connectivity
- MQTT publishing
- JSON telemetry
- Position reporting
In Development
Mesh Sensor
Industrial sensor node
Reads water level, pressure, flow, and temperature sensors wirelessly over the mesh.
- 4-20mA input
- Solar + battery
- Same enclosure as DropLink
- Configurable polling

Ideas & Future Work
Things we're thinking about but haven't built yet.
🚿
Irrigation Control
Solenoid valve control via mesh commands. Scheduled watering.
💧
Tank Level Sensing
Ultrasonic or pressure-based water level monitoring.
📷
Trail Camera Integration
Trigger alerts when trail cameras detect motion.
Open Source
All of this is built on open source tools. Meshtastic firmware, MQTT, PostgreSQL, InfluxDB, Grafana.
