This demo uses the gauge from Google charts to display temperature measurement values in degrees Celsius. It displays CLASS1.MEASUREMENT, Type=6/VSCP_TYPE_MEASUREMENT_TEMPERATURE values that comes from sensor=4 a fridge in our house. This is real live data.
The websocket connection used here is a secure TLS connection to the VSCP MQTT demo server. You can freely test this server for VSCP related experiments. It gets real time live events published from my (akhe) office and home. See the link for information of events published.
