Added a live power demo to the existing demo pages. This demo show the actual power usage in our house/office. Data is collected from a smart power meter with an open interface that is installed by our utility company Ellevio.
You can read more about the interfacing of this meter here. On this page you can also find a link to a Python script that does the job if you prefer using it instead of the VSCP driver approach.
Measurements are collected by a VSCP daemon driver vscpl2drv-energy-p1 and sent by the VSCP daemon to the MQTT broker on the vscp demo server. The VSCP daemon collecting data is installed on a Raspberry Pi 3B+ running Raspbian.
More demo data is on the way.

VSCP turns 21 today
Still alive!
The VSCP MQTT demo code is now also live on our demo server. This is probably the most ugly and boring demo around – it will improve over time – but the technique behind it is interesting. At the moment it basically just show the temperature in our fridge in some different ways. Not very interesting but it’s live and real time data.
It is also worth noting that everything is secured with TLS. From the source up to the actual widget.
The source generating data is a small device (Kelvin NTC10K) that does not have Internet capabilities but instead communicate over a CAN bus which is connected to a VSCP daemon which in turn publish received events to a local MQTT broker on JSON format. This data is then forwarded to the demo server.
With VSCP it is possible to write widgets like this once and then use them for different scenarios multiple times. Just by using the tools we all have been using for many years now. Things that web designer people do well.
Try yourself to plot the data using charts.js for example.
A new version of the package node-red-contrib-socketcan (1.2.2) was published at 2021-08-26T10:30:37.106Z
- Fixed dependencies
- Added LICENSE
Added some initial demo code for VSCP MQTT events over websockets. Currently a page with an unformatted live event list is available and a gauge displaying the fridge temperature in our kitchen.
The code is here https://github.com/grodansparadis/vscp-demo-mqtt-web
This is initial work and work in progress so please expect a lot of changes and improvements. Posted here for people that want to start development around this technique.
Information about the events available will be added as we go and more will come. There are some info in the wiki already but info is far from complete.
Added a python script that collect Bluetooth BLE sensor data from a Silicon Labs Sensorpuck and send it to a VSCP Daemon. Data collected is
- Signal Quality
- Battery Voltage
- Temperature
- Humidity
- Ambient Light
- UV Index.
The script is available here https://github.com/grodansparadis/vscp-python-sensorpuck and is including instruction on how to use and install.
Live data is available on the VSCP demo server and a node-red flow is included to show this data in real time.
