A  newer post  on the same subject !! The easiest way to test Your OpenPlotter, OpenCPN or SignalK(SK) applications is to use the supplied sample files in SK.

Homebridge, autostart made simple

Image
There have been some questions about how to handle Homebridge, (HB), autostart at power on and restart at failure using Raspberry Pi OS  systemd .  Please note that, in the later versions, the HB installation handles this !! I have written a post how to manually set it up but now in this post I will present a script which handles it automagically !!  Despite this simple set up I recommend using the app " hb-service", which is installed together with "homebridge-config-ui-x" How to install HB is found here !

Image
          Updated 2019-09-20 ! This Blogpost was initially made before the IKEA outlets was enabled in the Apple Home app. They could then just be reached via a Tradfri Homebridge plugin .  Since a while blinds are supported by this plugin but not by the IKEA Gateway and app so maybe its time again to install it ? Another post covers the installation of the Trådfri gateway with a HomeKit approach . (Without Homebridge) Other  HomeKit posts  on this Blogg
