APC UPS Binding

Hi

Thanks for all the great ideas and scripts in this post.

I couldn’t get my head around how the python script worked, but I did find a solution using the Exec binding.

I created a Thing in paperUI using the Exec Binding with the simple command of

apcaccess -u

I then linked the output to a String Item - in my case I called it “APCUPSQuery_Output”

this rule then splits the string into separate variables

(testtrigger is just a virtual switch that I use to trigger rules when I’m developing)

rule "APC UPS String spliting"
when
Item APCUPSQuery_Output received update // Change this Item to your "apcaccess -u" exec query output
// or Item testtrigger changed	// Only a test switch to force the rule to run for testing

then 


	logInfo("APC Info", "APC UPS Query update = "+APCUPSQuery_Output.state)	// Change this Item to your "apcaccess -u" exec query output // Comment out this line to stop it populating your openhab.log file

	var String APCQUERY = APCUPSQuery_Output.state.toString	// Change this Item to your "apcaccess -u" exec query output

	
	
	
	var APCname 		= (APCQUERY.split(':').get(14)).split('\n').get(0) // The (\n) split removes the line feed and wrapped text from the result.
	var APCOnline		= (APCQUERY.split(':').get(15)).split('\n').get(0)
	var linev			= (APCQUERY.split(':').get(16)).split('\n').get(0)
	var LOAD 			= (APCQUERY.split(':').get(17)).split('\n').get(0)
	var loadNo 			= Float::parseFloat(String::format("%s",LOAD)) 			// turns the string into a usable number
	var batterych		= (APCQUERY.split(':').get(18)).split('\n').get(0)
	var batterychNo 	= Float::parseFloat(String::format("%s",batterych)) 	// turns the string into a usable number
	var timeleft		= (APCQUERY.split(':').get(19)).split('\n').get(0)
	var timeleftNo 		= Float::parseFloat(String::format("%s",timeleft)) 		// turns the string into a usable number
	var outputv			= (APCQUERY.split(':').get(23)).split('\n').get(0)
	var outputvNo 		= Float::parseFloat(String::format("%s",outputv	)) 		// turns the string into a usable number
	var itemp			= (APCQUERY.split(':').get(30)).split('\n').get(0)
	var itempNo 		= Float::parseFloat(String::format("%s",itemp	)) 		// turns the string into a usable number
	var battv			= (APCQUERY.split(':').get(32)).split('\n').get(0)
	var battvNo 		= Float::parseFloat(String::format("%s",battv	)) 		// turns the string into a usable number


	logInfo("APC Info","APC UPS Named "+APCName+" is "+APCOnline+", with an internal temperature of "+itempNo+"°C,  Load = "+loadNo+" Percent, Current Line Voltage is "+linev+" Battery is at "+batterychNo+" percent, giving "+timeleftNo+" minutes at current load, at "+outputvNo+" Vac. Current battery voltage "+battvNo+" Vdc")    // Comment out this line once you're happy the rule is working for you.

//	You could use the values to populate Items for use elsewhere, for example

//	APCname.postUpdate(APCName)
//	APCOnline.postUpdate(APCOnline)
//	APClinev.postUpdate(linev)
//	APCLoad.postUpdate(loadNo)
//	APCbatterycharge.postUpdate(batterychNo)
//	APCtimeleft.postUpdate(timeleftNo)
// 	APCoutputv.postUpdate(outputvNo)
//	APCbatteryvoltage.postUpdate(battvNo)

end

This gives me a loginfo output of :-

2019-02-21 10:53:25.870 [INFO ] [ipse.smarthome.model.script.APC Info] - APC UPS Named Smart-UPS 2200 XL is ONLINE , with an internal temperature of 11.2°C, Load = 7.1 Percent, Current Line Voltage is 239.0 Battery is at 100.0 percent, giving 1020.0 minutes at current load, at 239.0 Vac. Current battery voltage 55.4 Vdc

Thanks to @rlkoshak for his help yesterday with splitting strings, I’m still not entirely sure how to implement his parts idea, but I’m working on it :slight_smile:
