          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

In a former post I used Homebridge on a Raspberry Pi , to make Z-wave devices appear in the Apple Home app, but there is a simpler and faster, way. Start with the install of the Razberry card or upgrade to Z-way V3.0.0 Other  HomeKit posts  on this Blogg

Updated 2019-08-10 ! New to Node-Red(NR) and maybe start with a simple application You can benefit direct from ?

My thoughts, about NMEA WiFi have finalized ? since my first post in the subject  and the Yacht Devices YDWG-02N is now installed in my NMEA2000/ST/NMEA0183 network and works just fine.  I'm already using Raymarine ST => ST NG converter but otherwise I had bought the YDNR-02  instead which should have done the same job. Please find some thoughts from the installation below.

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 .

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.

Updated 2019-03-18 ! 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. Other  HomeKit posts  on this Blogg
