I thought I would share a bit.
I want to point out that I was not aware of the work already done by @rtvb regarding the same problem I encountered.
The System Binding gives access to the CPU uptime in minutes. I like this value because it gives me a measure of how stable the system is.
I wanted to have a more readable format for the value. For instance 2365 minutes doesn’t mean much but 1 day 19 hours 25 minutes is more ‘human’.
So I made a Javascript transform file named CPUTime.js that need to be placed in the transform folder.
Note that you will need the javascript transform installed!
/*
Javascript transform function to change the number
of minutes of CPU time from the System Info Binding
into a more readable format
eg: 2365 into '1 day 15 hours 25 minutes
The item in the items file is defined as follow:
Number LocalComputer_Cpu_SystemUptime "[JS(CPUTime.js):%s]"
and linked via PaperUI to the System uptime channel
of the System Info Thing
*/
(function(i) {
var val = parseInt(i); // The value sent by OH is a string so we parse into an integer
var days = 0; // Initialise variables
var hours = 0;
var minutes = 0;
if (val >= 1440) { // 1440 minutes in a days
days = Math.floor(val / 1440); // Number of days
val = val - (days * 1440); // Remove days from val
}
if (val >= 60) { // 60 minutes in an hour
hours = Math.floor(val /60); // Number of hours
val = val - (hours * 60); // Remove hours from val
}
minutes = Math.floor(val); // Number of minutes
var stringDays = ''; // Initialse string variables
var stringHours = '';
var stringMinutes = '';
if (days === 1) {
stringDays = '1 day '; // Only 1 day so no 's'
} else if (days > 1) {
stringDays = days + ' days '; // More than 1 day so 's'
} // If days = 0 then stringDays remains ''
if (hours === 1) {
stringHours = '1 hour '; // Only 1 hour so no 's'
} else if (hours > 1) {
stringHours = hours + ' hours '; // More than 1 hour so 's'
} // If hours = 0 then stringHours remains ''
if (minutes === 1) {
stringMinutes = '1 minute'; // Only 1 minute so no 's'
} else if (minutes > 1) {
stringMinutes = minutes + ' minutes'; // More than 1 minute so 's'
} // If minutes = 0 then stringMinutes remains ''
var returnString = stringDays + stringHours + stringMinutes
return returnString.trim(); // Removes the extraneous space at the end
})(input)
The item in defined as follow:
Number LocalComputer_Cpu_SystemUptime “[JS(CPUTime.js):%s]”
And I linked it with PaperUI to the CPU uptime channel of the System Binding Thing
Finally in Habpanel I have a dummy wigdet linked to the item and with the ‘Use server-provided format if available (openHAB 2)’ option ticked
The result is:
I hope this can help
