[SOLVED] Format uptime System Info binding

Setup, Configuration and Use Runtime
, ,
21

I used your rule and changed it to my Items.
Rule:

rule "format uptime"
when
    Time cron "32 0/5 * * * ?"
then	
	var int days = (Sys_OH2_Uptime.state as DecimalType).intValue / (24 * 60)
	var int hours = ((Sys_OH2_Uptime.state as DecimalType).intValue / 60) - (24 * days)
	var int minutes = ((Sys_OH2_Uptime.state as DecimalType).intValue - 60 * (24 * days + hours))
	var String result = ""
// days
	if (days > 0) {
		result = result + days + " Tage / "
	}
// hours
	if (hours > 0) {
		result = result + hours + " Std. / "
	}
// minutes
	if (minutes > 0) {
		result = result + minutes + " Min."
	}	Sys_OH2_UptimeFormatted.postUpdate(result)
	logInfo("system.rules", "Uptime updated to " + Sys_OH2_UptimeFormatted.state)
end

My Items:

Number Sys_OH2_Uptime "Uptime [%s]" (gSys) { channel="systeminfo:computer:openhab2:cpu#uptime" }

Number Sys_OH2_UptimeFormatted "Uptime Formatted [%d]" (gSys)

But I get an error in the logs:

2018-11-11 11:00:32.124 [WARN ] [rthome.model.script.actions.BusEvent] - Cannot convert '7 Std. / 59 Min.' to a state type which item 'Sys_OH2_UptimeFormatted' accepts: [DecimalType, QuantityType, UnDefType].

What is the problem here?
Any Ideas?

Hey Robert,
thank you for this solution. Works perfectly here at my Raspi

25

I tried the script from @rtvb (thanks), that works for basicUI, but not for PaparUI. Is there anything changed in the past two years regarding transformation within an item label?
upper part = paperui, lower part is basicui:

PaperUI is still an administrators interface for system setting up and testing etc., and is not intended to have nice presentation goodies.

Thanks, too bad. Administrator interface or not, i think it should have the transformation in place, for testing purpose etc. Anyway, with the all new UI that is being developed for 3.0 i don’t think anyone should waste their time implementing it for paperui :slight_smile:

it works for me as well but I do not like so many logs to be pushed.
In your example @pbogocz you run the rule every 5min and 32sec. do you observe so many logs as rule launch?

It seems info log are being pushed until 1min overclock. every sec. or less.
Does it mean the script and the maths are being done with the same frequency ot it is being done one. It is strange and not efficient, unless I am wrong.
