I love dashboards and graphs - I always have, even back to early days with network equipment and tools like MRTG and the like. Seeing data on a graph helps to learn about how something is working over time, identify trends, and look for problems.

Dashboards on boats have been a challenge until Signal K and the InfluxDB plugin. It's relatively easy to set this up, and the amount of flexibility you have with Grafana to create dashboards is amazing. I continue to think of new ways to show things that I know will be fun to explore.

I've updated my existing weather dashboard that I covered a few months ago, and created and added some new ones. Teppo Kurki and I covered these in our recent webinar, which is linked in the article below.

Check out the new dashboards!

Engine and power dashboards

Engine and power dashboards
I have discussed my weather dashboard before in Real-time weather from the boat, but I have always wanted more visibility into other areas. I have a couple of new dashboards for engine performance and the electrical system.

Correction - AC Power Isolation

I recently posted an article about a new product I had installed to help with AC power isolation. Very quickly after posting, readers Charlie Johnson and Jim Healy commented on the post around concerns on how it was installed, as well as the lack of ABYC compliance in the product design.

I pride myself in documenting projects with technically backed, facts based research. I consulted with an ABYC electrician prior to purchasing, and during the install of this product. I also contacted the manufacturer and asked questions about the product. At no point was it outlined that this product does not fully conform to all necessary ABYC standards.

Given the potential shock hazard from the installation method, and the ABYC compliance issues, I have removed the product from use on my boat. Hopefully the manufacturer will be able to become complaint with ABYC standards, or have them updated to include their product.

Problems with T-Mobile voice+data plans and Peplink CAT18

Problems with T-Mobile voice+data plans and Peplink CAT18
T-Mobile have apparently blocked the T-Mobile One lines that have both data and voice from using a Peplink CAT18 router with the Telit LM960 modem.

Peplink MAX HD1 Dome

Peplink MAX HD1 Dome
I am testing the CAT18 version of the Peplink MAX HD1 Dome and SIM Injector against the MAX Transit with Poynting OMNI-402 antennas, and recorded an overview video as well.

What’s Next?

I’m working on a few things that I hope you will be interested in:
  • 4" displays
  • My Furuno system
  • Rendezvous 2020 internet setup
  • Router testing results (lots of these)
  • How I test routers / LTE stuff
If you’d like to request something specific, or if one of these is more interesting to you than another, please reply and let me know!
