Hi. I’m so glad I converted to OpenHAB2, as its functionalities and binding of all kinds of products is eminent… But for now I’m facing a little problem. A problem which 78% of you good guys probably can solve in seconds. I’m getting a number (count down timer) from my IHC, but this number is unr…

You need to provide a lot more details. Post your relevant items. What binding do you use to get the count down number from the IHC? What have you tried thus far? What are the errors, if any, in your logs? What openHAB panel? Do you mean BasicUI, PaperUI, Habpanel? What do you mean by unreadab…

First, thanks for helping me out here. My items file looks like this: Number livingroom_timer1 “timer1” (Livingroom, Lights) { ihc=“xxxxxxxxx” } When the timer starts counting down in IHC, I get the number 36000 in my OpenHAB Panel.. I’m showing it in my panel like this: { “name”: “Timer 1”, …

Try adding the value of the Item’s state to the Item’s label. I’m assuming you are using Habpanel (it is not named openHAB Panel). I’ve little experience with it. Anyway: Number livingroom_timer1 "Timer 1 [%d]" (Livingroom, Lights) { ihc="xxxxxxxx" } In the phone apps and sitemap based UIs (Bas…

Thanks for that @rlkoshak I figured oyt that the number that is displayed, is 3600000 and this number is counting down OK. So the update of the Timer1 seems to work. If I can find a way to divide this number by 60000, I will get 60 minutes. The question is, will it count down OK?

I mean, its counting down from 3600000 (miliseconds is my best guess) as it is right now. But I want it to count down in minutes (so its 3600000 divided by 60000 equals 60 minutes). But I don’t know where to put this calculation…?

Like I said, create a rule or create a JS transform. http://docs.openhab.org/addons/transformations/javascript/readme.html http://docs.openhab.org/configuration/rules-dsl.html

OK. I’m not the born programmer, but I’ll give it a try. Thanks alot for your input :slight_smile:

As said, I’m not a programmer, but by reading this community, I’ve come up with this code, and put it into a rules file, but I get some errors. Can you tell me what could be the problem? val int totalMinutes = seconds/60 val int remainderSecs = seconds%60 val int totalHours = totalMinutes/60 va…

@Tonny_Kohler you may want to repose using code fences: use three tick marks ``` ( ` is the symbol for tick mark) before and after your code, that will make it much more readable, right now it is very hard to read. You can also use code fences picking the symbol on the top line in the window where…

You either need to use a Rule and a Proxy Item to store the result of the divide or use a JS transform and do the math in JavaScript in the Item’s label.

I don’t understand the question.
