Updated 2021-07-24 ! Many newer MFD:s don't have any  NMEA 0183(N1) connector. The   Axiom don't even have any Seatalk NG connector anymore, just the Device Net micro connector for NMEA 2000. 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 Pick N1 data from the AIS NMEA 2000, N2 to N1 konverte r SeaTalk NG, NG to N1 konverte r

Updated 2021-07-14 ! The dispatcher " aisdispatcher "(AISD), Linux v1.2, from AISHub.net receives NMEA 0183 VDM/VDO messages , (NAIS) via an UDP/TCP connection, or serial interface, and forwards it to one or several destinations as UDP streams. It works at command line with no GUI. Please note ! This software is "labeled" deprecated and the AISHub guys recommend you to use this package , with built in GUI, instead. The old version, described in this post,  still works, for RPi OS before Bookworm , and is very lightweight. The best AIS application ?  is found here  !

Updated 2021-07-07 ! Sometimes the syntax for the Javascript in Node-Red is a little hard to get, despite some Googling. This was evident when i tried the run the " node-red-node-mysql " node inserting data in a MySQL database. Also timestamps in different environments are a little complicated. So this post will cover both areas with some code examples done on a Raspberry Pi.

Updated 2021-06-15 It's always nice to have ALL information at the same place, navigator/plotter, when You are out with the boat.  What could be missing is the engine information/data. If You have a Volvo Penta from 2006 or later it could be pretty easy. There are some "standard" NMEA 2000 gateways to choose from, for example;  Volvo Penta has it's own 22813366, 3889758 Raymarine ECI-100 Maretron J2K100 .....

Updated 2021-05-21 ! 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, acts as a messenger; the more devices you have, the more powerful and strong your network is. Raspberry USB SSD boot made simple ? Check link  

Updated 2021-04-15 ! A cheap and simple way to measure temperature, and have it displayed in the Home app, is to connect one wire (1W)  DS18B20  (DS)temperature sensors direct to the Raspberry Pi(RPi) and install a DS plugin. This assumes that You have Homebridge up and running on a Raspberry Pi  Check this post !!    "ANY" temp source  can be HomeKit enabled.

Sometimes you have to handle things in Wordpress that you can't find any plugin for. In our case I had to visualize a list from a MySQL database and in another case I had to fetch data from another website. In both cases I solved it with inserted PHP code which is executing and getting the info.

Updated 2021-03-13 ! Here I'm trying to do the "ultimate" SignalK switch blog post including( no N2K) Shelly 1 as the hardware switch NodeRed as the function engine NodeRed dashboard as input/output interface WilhelmSK as input/output, check picture A http endpoint as state sensing The post is ment to be a template where you can pick the parts which are right for your setup.
