I just want to present some new stuff I have been working on during the last week. It is still initial work but still quite useful. Also beware. This is JavaScript, PHP and MySQL and I am an embedded programmer. But I have asked for help from people who know these things but got no response so here I go and do it myself as usual. If someone wants to step in and help or even take over this project he/she is more than welcome, I have tons of other things to attend to.
There will be a proper howto and a manual at a later stage. This document is just some information and a demo.
First: Why?
Answer: I need this for my own use. Actually I needed it because I have two compost containers where I have temperature sensors and I was curious of the temperature in them now in the winter when it is cold. Well I have some other temperature sensors around the house and the office that maybe can tell me something also.
If you know VSCP you also know about the VSCP ux framework. It is really a nice set tools that allows for building fast, reliable, secure and responsive user interfaces with live data. It uses the websocket and the REST interfaces of the VSCP daemon to communicate between ux elements and the VSCP subsystem. We talk state of the art security here, at least if SSL is used. But sometimes it may feel awkward to export interfaces of an in operation/house critical piece of computer hardware anyway. This is therefore another way you can share data. A cloud solution if you like. But something you are in charge of yourself.
To use VSCP mv (VSCP measurement visualization) you need an Internet server provider that gives you a mysql/mariadb database. Most does, at least here in Europe. Well you can have your own server that do this also of course.
Secondly you setup the VSCP daemon to send the data you want to share. This you do by adding a decision matrix element to your local VSCP daemon.
Third you configure what data you want to share by adding some entries in the database.
Your are ready to go.
Now you can visualize your data
This is the temperature outside at my place. With the “select source” at the bottom you can look at the temperature in my office and in the mentioned compost containers. The interface works on different hardware, phones, tablets and computers. Using iframes you can include it in other web pages. This is live and dynamic data.
This is another way to look at the same information. Some more variants of this may come in the future.
If you instead wants a diagram you have that here for the current day, which is the default. The diagram will update as time goes. If you prefer to see the temperature 2018-03-16 between 00 and 03 you can of course.
And if you rather want to see the current temperature in my office it is possible or in the compost 1 container or in the compost 2 container.
But if you rather just want to investigate data this collecting interface may be the best place to get a hold on it.
And there are all temperature measurements here. But don’t be fooled. Any of the VSCP’s measurement values can be shown.
But…
you say. I want to use my own diagram/Table tool to visualize data. I will not stop you. It’s a free world. If you can read JSON your on
Read the defined seco devices. SECO = SEnsor, COntrol. Or read the current value for a SECO. Or read data in a date/time range for a seco.
As I said I will come back with a manual and a howto at a later point. Well a link to the software also of course.
For me the info that the microorganisms in the compost container holds it at zero degrees Celsius or just above was worth the effort in constructing this.
