Hi.
In my city there is a car rotation and you cannot go out with the car one day a week and at a specific time.
I installed a tablet on the wall next to where we kept the keys with a HABpanel panel.
I would like to have an alert message or image displayed on this panel only on the day and at the specified time.
What is the simplest way to do this?
I don’t have much knowledge of programming.

Create string item
Create two cron rules, the first is temporarily allowed, the second is not allowed. In the rules, set the item value to the desired text. Show this item in the habpanel.
I’m trying to use Visual Studio to do that but I don’t know how.
I’ve made this:
rule “”
when
<0 50 8 ? * TUE *> [or <TRIGGER_CONDITION2> [or …]]
then
end
Can you show an example, please?
file_name.items
String MyStrItem "Message string [%s]" (gRestore)
file_name.rules
rule "cron1"
when
Time cron "0 0 5 * * ? *"
then
MyStrItem.postUpdate("String1")
end
rule "cron2"
when
Time cron "0 0 15 * * ? *"
then
MyStrItem.postUpdate("String2")
end
Every rule must have a unique name
Rule “myCronRule”
Rule cron triggers look nothing like that.
There are many hundred examples in this forum or you might even try the docs
It’s working nice
Thank you very much
Do you think it’s possible to use images instead of words using the same process?
Everything was fine. Then I tried to use an image instead of a text to warn abou the car restrictions.
After I use this command
import java.io.ByteArrayOutputStream
import java.net.URL
in a .rules file the text item is sending only NULL.
These are the files that was working before:
rod.itmes
String MyStrItem “Message string [%s]” (gRestore)
rod.rules
rule “cron1”
when
Time cron “0 0 7 ? * WED *”
then
MyStrItem.postUpdate(“RODÍZIO”)
end
rule “cron2”
when
Time cron “0 0 10 ? * WED *”
then
MyStrItem.postUpdate(“LIBERADO”)
end
rule “cron3”
when
Time cron “0 0 17 ? * WED *”
then
MyStrItem.postUpdate(“RODÍZIO”)
end
rule “cron4”
when
Time cron “0 0 20 ? * WED *”
then
MyStrItem.postUpdate(“LIBERADO”)
end
Is there a way to retrieve the previous condition?
tks
Sorry, my English is very bad, I don’t think I understand your problem.
First, use code fences, “</>” button, to make your code example readable
You have several rules with one content, but different trigger, combine them:
rule "cron1"
when
Time cron "0 0 7 ? * WED *" or
Time cron "0 0 17 ? * WED *"
then
MyStrItem.postUpdate("RODÍZIO")
end
And if I understood you correctly, you want to have an icon instead of text, but you use HabPanel to display, in that case, do it in the HabPanel.
I’m not a hub panel specialist, you will have to search the forum yourself for how to do this.
Here’s an example for a starting point, add a standard widget template and paste the following code into it:
<span ng-style="{ 'font-size': '32pt' }" class="value ng-binding">{{ itemValue('MyStrItem') }}</span>
<div ng-if="itemValue('MyStrItem')=='Rodizio'">
<widget-icon size="'128'" iconset="'eclipse-smarthome-classic'" icon="'light'" state="'on'" class="ng-scope ng-isolate-scope"></widget-icon>
</div>
<div ng-if="itemValue('MyStrItem')=='LIBERADO'">
<widget-icon size="'128'" iconset="'eclipse-smarthome-classic'" icon="'light'" state="'off'" class="ng-scope ng-isolate-scope"></widget-icon>
</div>Here’s another option:
I’m sorry about that. <>
Thanks for your response.
My english is a working process. Maybe you speak Portuguese 
I was being a stupid. The word was not showing because of the cron time I configured. As soon as the time comes the word shows up. That’s working fine.
I’m in the process to use image instead of just words
Thank you for your help
This works fine too.
Can you show how to use an image instead of the word RODIZIO?
I have the guarda.png image inside the html folder.
I’ve created an item on Paper UI called RodizioIMG with Image type and this .rules
<
rule “RodizioIMG”
when
Time cron “0 0/1 * 1/1 * ? *”
then
RodizioIMG.postUpdate.Image url=“http://192.168.2.112:8080/guarda.png”
end
but my log says this
Error during the execution of rule ‘RodizioIMG’: An error occurred during the script execution: index=1, size=1
The cron time is this way just to test every minute if it is working, I’ll change for “0 0 7 ? * WED *” and “0 0 17 ? * WED *” later
tks
In the example that I wrote to you above, the image changes when the word (your two words) changes, look carefully at the code, you will understand, but the image is taken from standard icons, for example I made a light bulb. And according to the link I gave you, it is written how to substitute your image instead of an icon.
you don’t need to do this, just put 2 images in the “html” folder
see here for an example
you get something like this:
<span ng-style="{ 'font-size': '32pt' }" class="value ng-binding">{{ itemValue('MyStrItem') }}</span>
<div ng-if="itemValue('MyStrItem')=='Rodizio'">
<img src="/static/rodizio.jpg"/>
</div>
<div ng-if="itemValue('MyStrItem')=='LIBERADO'">
<img src="/static/liberado.jpg"/>
</div>

Thank you very much.
That’s perfect.
I’m making the same thing to show the days the garbage truck comes. How can I show an image on those days but don’t show anything during the other days? Everything I try returns NULL.
I did this to show nothing after the garbage truck hours:
on rules:
rule "cron1"
when
Time cron "0 0 18 ? * TUE,THU,SAT *"
then
LixoItem.postUpdate("LIXO")
end
rule "cron2"
when
Time cron "0 0 21 ? * TUE,THU,SAT *"
then
LixoItem.postUpdate("")
end
on the widget I erased the second part:
<span ng-style="{ 'font-size': '25pt' }" class="value ng-binding">{{ itemValue('LixoItem') }}</span>
<div ng-if="itemValue('LixoItem')=='LIXO'">
<img src="/static/lixo.png"/>
</div>
but I think this is not the right way, although it’s working.
Is that right?
I’m not an expert in the habpanel, I just did it for you by searching and examples. I think if now everything is working as you wanted, then don’t touch it anymore 
You’re right.
tanks for your help.
