Speedtest vs ISP and at home

Updated 2020-11-30 !

Sometimes you are doubtful about the performance of your home network, or versus the ISP, and wonder, where is the bottleneck ?

After some Googling I found some favorite applications, implemented on a cable connected Raspberry PI(RPi), which do the job so You can start measure and stop guessing.

A speedtest, 

• checking Your ISP, with just a bash script
• for Your home network

SignalK, stream data changes

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 and subscribe to any change of data from the SK server.
