NavAlert NMEA 2000 Monitoring System from Digital Yacht makes debut at METS 2021

Digital Yacht will introduce NavAlert at METS 2021. It’s a new, universal monitoring and alert solution for boat systems capable of monitoring any parameter on the boat’s NMEA 2000 network. This could include engine or generator data such as temperature and pressure, navigation data such as depth, position, AIS, speed or wind or even the status of simple connected devices like pumps and switches. Custom alarm levels can be set and NavAlert will provide audible and visual alerts as well as logging the data and alerts…

Siren 3 Pro, boat monitoring evolved

Since the introduction of their first boat monitor nearly a decade ago, Siren Marine has been a leader and innovator in boat monitoring. The Siren 3 family of monitoring products encompasses their decade of experience and promises a comprehensive boat monitoring system. With wired, wireless, and NMEA 2000 sensors the system has the ability to monitor nearly every aspect of your boat, and it can even control your boat remotely. But, how does it all work together? I’ve been testing the Siren 3 Pro aboard Have Another Day and can share some results.

Littelfuse acquires Carling Technologies, Maretron included: Business as usual?

Littelfuse — a large Chicago-based manufacturer of industrial technology — is acquiring Carling Technologies, and that makes me a bit nervous about the future of Carling’s marine brands. Will Octoplex, MPower, and especially all the (great) Maretron electronics on my boat continue to be developed and supported even though Littelfuse currently has only a minor marine market presence?

NMEA 2000 network troubleshooting with Digital Yacht, Actisense, and DIY Tools

NMEA 2000 networks are pretty reliable but when there’s trouble it is often unclear where to start. Digital Yacht and Actisense have both brought out new products to help ensure the health of a network and better understand its operation. But, even if you don’t have any specialized tools onboard, you can still do some basic but effective troubleshooting of the health of your network. Let’s explore Digital Yacht’s NAVDoctor, Actisense’s A2K-TER-U smart NMEA 2000 terminator, and the troubleshooting you can do with an NMEA 2000 breakout cable and a multimeter.

Monitoring dew point temperature at your helm, why and how

Allan Seymour wants to see the current Dew Point and outside Air Temperatures at the helm of Sally W because fog is often about to shut in when the two temps become similar. And there are at least three marine sensors that claim to deliver dew point over NMEA 2000, two of which Allan owns. But actually getting the value to show on his instrument display turned out to be quite a challenge. I helped with the troubleshooting, and came to better appreciate the value of dew point in the process…

Victron’s Venus OS on a Raspberry Pi, install and configuration

The Victron Remote Management (VRM) portal and their Venus OS monitoring software deliver best-in-class access to information about your boat (, RV, or fixed solar) electrical sytem. But, running one of these systems has typically required Victron hardware which starts around $300. Victron has a long history of embracing the open-source community and they’ve continued that effort by supporting Venus OS on a Raspberry Pi. But, many people hear Raspberry Pi and either think dessert or that it’s over their heads and too complex. This guide walks you through the steps required to get Venus OS up and running on a Pi and sending data about your electrical system to VRM.
