A goiod friend from Germany, Andreas Merkle (BlueAndi), (old VSCP’ers knows him well as he done a lot of nice & valuable VSCP work) sent this video and I think it is so nice so I want to share it. Outside temperature here on the VSCP hill at 20:20 today as when the video was shot.

The device showing the info is Andys very nice project esp-rgb-led-matrix. Checkit out!

If you have mosquitto clients installed on a computer you can write

mosquitto_sub -h test.mosquitto.org -p 1883 -t vscp/#

and the sensors in my house will tell you that they are alive and report what they see. A lot of information. But if you change the command to

mosquitto_sub -h test.mosquitto.org -p 1883 -t vscp/25:00:00:00:00:00:00:00:00:00:00:00:0D:02:00:01/20/#

you will instead see when I walk into and out the door through my office.

If you dare you can write

mosquitto_sub -h test.mosquitto.org -p 1883 -t vscp/25:00:00:00:00:00:00:00:00:00:00:00:0D:02:00:02/1040/6/2/6/#

and you will get the temperature at our entrance. Or write

mosquitto_sub -h test.mosquitto.org -p 1883 -t vscp/25:00:00:00:00:00:00:00:00:00:00:00:0D:02:00:02/1040/6/2/0/#

to get the temperature in my office. Or if you are more interested in the outside temperature you enter

mosquitto_sub -h test.mosquitto.org -p 1883 -t vscp/FF:FF:FF:FF:FF:FF:FF:FF:61:00:08:01:92:AF:A8:10/10/6/16/0/#

And you will get the temperature at the south side of our house. And yes, you understand and interpret the temperature value correct if you are in Europe or in some other place of the world. It is that easy. That is tru for other measurements to

But there is a risk you go crazy if you start to dig into all of that info. After all it is to simple to work in the first place…
