Many newer MFD:s don't have any NMEA 0183, N1. The Axiom don't even have any Seatalk NG connector anymore, just the Device Net micro connector. Loosing the N1 info too for example the old VHF, position data for DSC,could be a problem so how to solve it ? Some solutions
Updated 2019-05-11 ! My old Mac Book Air, mid 2011, didn't support the latest MacOS, Mojave. So after some checking I found this brilliant fix which did the job. This guy have really done a fantastic job with great instructions and even a Youtube video.
Want to have a test environment for Node-Red, NR, separated from production, but on the same server/hardware ? Want to have separated instances for different applications on the same server/hardware ? It's pretty easy to have several instances running on the same server just temporarily or auto started at power on. Setup will follow for a Raspberry Pi, RPi ! A post for NR quick install.
Running Weather 34, W34, using my setup, the program "cumulusdata.php" is fetching data from Davis Weatherlink, WL, and are writing the data to a file, type Cumulus. The old way was to fetch the data via a scheduled cronjob. Doing a small change to "windspeeddirection.php", "updater.php" , and using the latest version of "cumulusdata.php", will do the update with the built in W34 refresh routine instead of cron job. Thanks to Ken who gave me the hint.
Do You have Telldus devices up and running and want them to be visible and used in Apples Home app ? With some software and a Raspberry Pi(RPi) they will appear in the HomeKit environment. Please note that as per 2017-10-22 the Telldus plugin is updated to V1.x and demands Node 8.3 or greater. Upgrade tips of Node from 6.x.x to 8.x.x is found here. The new version can also locally "talk" direct to a TellStick ZNet Lite Vx.
This is a setup, on a Raspberry Pi(RPi), with a software package, rPiAIS, from http://www.aishub.net which includes
receiving and processing of all standard AIS messages
streaming raw AIS feeds to multiple destinations
advanced monitoring of device status, coverage and message statistics
embedded electronic map with all received vessels
On the same RPi I have installed a RTL-SDR dongle, approx 20 €, as the AIS receiver and then using the software aisdeco2, 2 channel support, interfacing the dongle and sending NMEA 0183(N1) data to rPiAIS. Here is "stripped" version of an AIS receiver
Updated 2019-01-22 ! When starting up a new project with Raspberry Pi I like to start up fresh and with a minimal OS. Therefore i always use Raspbian Lite. Doing it right You don't have to use an external display, keybord and mouse, just the ssh client from Your Mac Connect the card reader, with the SD card inserted, to Your Mac and format the card with SD Formatter and use the "Owerwrite Formate" option. This will also check that the SD card is OK. Here You find a post with headless WiFi install.
To make a headless, (without monitor, keyboard and mouse) install of Raspbian, Raspberry Pi:s Operating system, on a Raspberry Pi(RPi) with built in WiFi and no LAN cable connection, please follow the instructions below. For example the RPi Zero and the newer Raspberry Pi 3 Model A+ don't have any LAN cable port so the setup can be quite usable.
Interface updated to WeatherLink 2.0(WL2.0) Migrate info in this post
If You want Your Private Weather Station(PWS) Davis Vantage Pro2, or other Davis products that use WeatherLink, to provide data for the template we use at Domstens Båtklubb just follow the instructions below. This is made without additional software such as Cumulus, Weather display or the Meteobridge product.
Updated 2019-01-07 !! As a part of one of my projects, the ultimate Weather site ?? Weather34(W34), I needed a WEB-host with PHP and started to use a Raspberry Pi. In this post You will get some short install tips on Apache with PHP on a Mac with Mojave, macOS 10.14.x, and at the end of the post the W34 installation is done.
If you think it's ok that the broadband speed appears as temperature in Home apps this plugin is very nice.
The plugin, used with Homebridge(HB), measures Your broadband speed at chosen intervals. If You use the free app "Eve for Homekit", besides that it shows the last measured broad band speed, it also shows the speed history in a nice graph.
New to Node-Red(NR) and maybe start with a simple application You even can benefit from ? This application is measuring Your Internet connection at chosen intervals using Speedtest.net and showing the result in a graph. If the speed is under a set value it will send You an email.
Sometimes you are doubtful about the performance of your network, or ISP, and wonder, where is the bottleneck ? After some Googling I found some favorite applications, implemented on a cable connected Raspberry PI(RPi), which do the job so You can start measure and stop guessing. A speedtest,
Updated 2018-11-04 ! These devices are available for Apples HomeKit. The devices are Bluetooth, BLE, or WiFi connected so it could be a limited range in Your house. The Z-Wave solution have a smarter setup running on a type of network called a "mesh network". One Z-Wave product will pass the signal along to another (“hop”) until the final destination is reached. Every device, not battery charged, in your home acts as a messenger; the more devices you have, the more powerful and strong your network is.
Extending Your WiFi via cable have the advantage, compared to extending via WFi, that You keep the bandwidth at max. Extending Your WiFi with products that use the same frequencies, as Your WiFi, will just put through 50% of the data flow.
One way to extend the WiFi is with a cheap router, or maybe an old router You don't use any more.
