  I really like the products on AliExpress and Alibaba, but in most cases the documentation is very simple and to short. So when I bought a combined tracker and a burglar alarm, to our boat, I really tried to get the best. One important thing was that, if possible, getting a lifetime app support. The purchase went well and 14 days later it arrived in Sweden.

It's almost become a sport to revive old Macs..... 😉 This short post will address some obstacles found during install of a new OS. The Mac Mini:s WiFi controller wasn't found ! The MacBook Air didn't manage to do a USB boot with Ubuntu !

Updated 2025-06-28 ! Are You searching for a solution where You want to create graphs and gauges from SignalK(SK) data ? Use NodeRed(NR), installed as a SK plugin , with the standard dashboard and it's easy to create info as seen in the picture. And this is without a database as InfluxDB and tools like Grafana. You use the WebSocket interface , or SK subscribe nodes, to subscribe to changes in data from the SK server. 

Updated 2025-06-23 ! I have got some questions installing, just,  Signal K (SK) so will do a summary with links. Signal K is the hub to receive data, from different devices in different data formats, and send it on to different equipment, or databases, in different formats. Most common for standard marine equipment are the old NMEA 0183 and the newer NMEA 2000 protocol which is also handled.  Besides the SK "hub" function developers  have  created  plugins  for different purposes. This is due to that  SK is open-source ! Sharing is caring ! In this post you can check the devices I'm using connected to the SK server and also my setup.

We’ve been using Mobile Broadband for several years and have always been keen to measure the speed from our Internet Service Provider (ISP). I’ve posted several variants , mostly Node-RED(NR) flows and programs that often use Python. I’m now slowly converting to Home Assistant(HA), and was glad there was an integration,   Speedtest , to do the job.  But I couldn’t get it to work since HA didn’t like that the test took more than 10 seconds,  Then I tried a Speedtest NR node, but it didn’t install because it needed Python dependencies...... (NR was installed as a HA "Add-on")
