Low cost zigbee (wireless) sensors are readily available for use on doors, hatch, portholes; along with more intelligent sensors for Smoke, Carbon Monoxide, Temperature, Humidity & Motion. With a low cost zigbee gateway & the SignalK zigbee plugin, these can be simply integrated into Signal K forming a powerful wireless sensor network.

Integrating Signal K with the Meshtastic LoRa mesh network enables off-grid, no-cost boat-to-shore communication and telemetry. You can monitor your boat’s status and receive alerts without relying on cellular or satellite connections.
