A turn of the Digital Crown changes my boat’s course. Here is why I use it, how Signal K makes it possible, and what you need to try it on your own boat.

An example of using Pushover for signalK remote notifications across Android and IOS devices; and an inexpensive beeper locally that will ensure it wakes you in the middle of the night.

Monitoring of Starlink using a custom DC-DC boost (57VDC) power supply with SignalK, Starlink plugin & sensESP.

Interface SignalK with an existing Hella Marine LED module to monitor and control LED lights.

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.
