Updated 2023-11-09 ! The AIS posts on this blog have been very popular so this post will be a follow up which will enable You to show AIS targets, including AtoN:s, on  OpenSeaMap , (OSM), together with buoys and beacons. The application showing the map is SignalK , (SK) a OpenSource project for marine use.  With the " ais-forwarder " plugin you could send/dispatch the NMEA AIS data to   Marinetraffic  or  Vesselfinder . Another   AIS-dispatcher . The best AIS application ? is found here !

Updated 2023-11-08 for Bookworm ! The purpose of a watchdog timer(WD) is very well described here but a more practical answer is; If your Raspberry Pi(RPi) "freezes", or hangs, it will automagically reboot within a very short time. This is made with a combination of hardware and software which is all ready available, on the RPi, and just have to be enabled. After some hours Googling and testing these are my findings !

Updated 2023-11-06 ! I have searched for a solution transmitting the NMEA data, from the navigation network, via WiFi, to for example  iSailor  or other Tablet/Phone applications. Most of these applications just accepts NMEA0183(N1) but many boats are also using SeaTalk 1(ST1) and NMEA2000(N2K). This post will cover, kept compact, my best findings covering both a DIY and a commercial approach to handle the different protocols.

Updated 2023-11-05 ! An introduction to the SignalK, Marine application, is given here . A very easy way to measure temperature with Raspberry Pi, RPi, is to connect one wire (1W) DS18B20  (DS)temperature sensors direkt to the RPi GPIO. Here You find a post where the temperatures are transfered via WiFi

Updated 2023-11-04,  OK with Bookworm 32 bit ! Not Bookworm 64 Bit ! This is a setup, on a Raspberry Pi(RPi), with a software package, AIS Dispatcher, 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 The best AIS application ?  is found here  !
