Not sure if this topic makes sense. I didn’t know how to call it.
I’m wondering if this is possible, maybe I don’t have the right combination of how to do it, but I have tried to tinker and not seemed to be able to get it right.
What i’m doing is taking a time in seconds from my 3D Printer that is publishing to my MQTT server then using a javascript (PrintTime.js) that takes the the seconds and converts it to Days, Hours, Min, Sec.
This is how my items is set up, and it works. Only problem is that it does not auto refresh/update on my sitemap, and I have to refresh the page every time I want to see the updated time.
Below is my item config for this.
`
Number Enders3_EstimatedTime "Estimated Time [JS(PrintTime.js):%s]" <clock> (gEnders3) {mqtt="<[mosquitto:octoprint/progress/printing:state:JSONPATH($.printer_data.job.estimatedPrintTime)]"}
`
Is there a way I can take that script and automatically run it through the JSONPATH Transform before it gets updated to my item itself, ( Hoping that this will make it automatically update on the sitemap).
I’ve tried something like this but it says I have errors with the transform.
Number Enders3_EstimatedTime "Estimated Time: [%s]" <clock> (gEnders3) {mqtt="<[mosquitto:octoprint/progress/printing:state:JS(PrintTime.js):JSONPATH($.printer_data.job.estimatedPrintTime)]"}
Not sure if this is possible or not, or if I have to go through a rule to get what I am looking to get. Any help is appreciated.
(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;
var seconds = 0;
if (val >= 86400) { // 86400 seconds in a days
days = Math.floor(val / 86400); // Number of days
val = val - (days * 86400); // Remove days from val
}
if (val >= 3600) { // 3600 seconds in an hour
hours = Math.floor(val /3600); // Number of hours
val = val - (hours * 3600); // Remove hours from val
}
if (val >= 60) { // 60 seconds in an minute
minutes = Math.floor(val /60); // Number of hours
val = val - (minutes * 60); // Remove hours from val
}
seconds = Math.floor(val); // Number of seconds
var stringDays = ''; // Initialse string variables
var stringHours = '';
var stringMinutes = '';
var stringSeconds = ‘’;
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 ''
if (seconds === 1) {
stringSeconds = ‘1 Second’; // Only 1 second so no ‘s’
} else if (seconds > 1) {
stringSeconds = seconds + ’ Seconds’; // More than 1 second so ‘s’
} // If seconds = 0 then stringMinutes remains ‘’
var returnString = stringDays + stringHours + stringMinutes + stringSeconds
return returnString.trim(); // Removes the extraneous space at the end
So I did get it to work by just creating a simple rule and it updates on the sitemap correctly how I would like it to by doing the following… (for further searchers like myself )
rule "Update Print Time"
when
Item Enders3_PrintTime changed
then
Enders3_PrintTime.postUpdate(transform("JS","PrintTime.js",(Enders3_PrintTime.state as StringType)))
end
(function(jsonString) {
//JSON BIT
var data = JSON.parse(jsonString)
var val = parseInt(data.printer_data.job.estimatedPrintTime);parse into an integer
//YOUR RULE
var days = 0; // Initialise variables
var hours = 0;
var minutes = 0;
var seconds = 0;
if (val >= 86400) { // 86400 seconds in a days
days = Math.floor(val / 86400); // Number of days
val = val - (days * 86400); // Remove days from val
}
if (val >= 3600) { // 3600 seconds in an hour
hours = Math.floor(val /3600); // Number of hours
val = val - (hours * 3600); // Remove hours from val
}
if (val >= 60) { // 60 seconds in an minute
minutes = Math.floor(val /60); // Number of hours
val = val - (minutes * 60); // Remove hours from val
}
seconds = Math.floor(val); // Number of seconds
var stringDays = ''; // Initialse string variables
var stringHours = '';
var stringMinutes = '';
var stringSeconds = ‘’;
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 ''
if (seconds === 1) {
stringSeconds = ‘1 Second’; // Only 1 second so no ‘s’
} else if (seconds > 1) {
stringSeconds = seconds + ’ Seconds’; // More than 1 second so ‘s’
} // If seconds = 0 then stringMinutes remains ‘’
var returnString = stringDays + stringHours + stringMinutes + stringSeconds
return returnString.trim(); // Removes the extraneous space at the end
})(input)
Your new item:
String Enders3_EstimatedTime "Estimated Time [%s]" <clock> (gEnders3) {mqtt="<[mosquitto:octoprint/progress/printing:state:JS(PrintTime.js)]"}
Actually David wrote it so you can chain transforms. But I have no experience with it so can’t tell you how to do it.
I couldn’t find an example but I know he talked about it being possible. Maybe it’s something that is planned? Yep, found it, it’s in work and not yet available. Mqtt 2.5
Not sure how i would even start to do that
