Change Alert Icon set

[athoopen]

All,

I created a pollen, migraine and rheumatism device. I use 3 Alert virtual devices for this. This Alert device has 5 levels (0...4) with associated Icons. I like to create a specific icon set for the pollen, migraine and rheumatism devices. I created the icons (0...4) and the general one, created the icon.txt file, put it in a zip and uploaded. However, after I push the Upload button, I get the error: "No icon definition file found."

I created successfully many On/Off icon sets, but what is the syntax for the icon.txt file in case of an "Alert". Currently, it is:

Migraine;Migraine;Migraine;Migraine;Migraine;Migraine

Which was my best guess (name for all the states (0..4) plus the general name).

Anybody knows the syntax of the icon.txt file incase it's not On/Off

TIA!!!

[athoopen]

I debugged the database and found that the table customimages holds all the custom images you uploaded. It shows that there are only two states, On and OFF. Therefore, I conclude that I cannot create Icon sets which holds more than two states ..... that's a pity.

I'm stuck, I think I will enter a change request, or do you have other options/ideas ...

I created a pollen, migraine and rheumatism device.

I am interested in a pollen device. Will you explain to me how you achieved that? Do you want to share the script used?

Thanks in advance.

No Problem Jan!!

First create a dummy virtual switch and create there a virutal switch of type "Warning" (Waarschuwing) with an approrpiate name (Hooikoorts???)

On the pi create the follwoing scirpt in /usr/local/bin:

Add the following line to the crontab on your pi

Code: Select all

03 * * * * /usr/local/bin/hooikoorts

In Domoticz create a dzEvents (Timer) script). Replace the content of this with the following:

Code: Select all

    local scriptVersion = '1.0'

    if riskLevel == 0 then Kans="Zeer klein" end

    MessageText = "Kans " .. Kans .. " bij " .. text
    
    if alert_device ~= nil then
        domoticz.devices(alert_device).updateAlertSensor(riskLevel, MessageText)
    end
end
}

Save it and switch it on That should do the trick.

The script gets the info from the weeronline webpage. Creates a json file and sends it to Domoticz . Domoticz picks it up, processes the json file, and updates the virtual sensor. The code is bases on the code which you can find at https://pon.fr/dzvents-alerte-pollens/ I just made it work for weeronline.

Hope you will enjoy it as much as I do (thanks to our French friend).

PS: the implementation for migraine and rheumatism is more or less the same. If interested, let me know, happy to share the code.

[waltervl]

Nice work!
Technically it should be possible with one dzvents script that reads the website and updates the Domoticz device(s).

[Jan Jansen]

Dear Arjan,

Thank you for sharing your script. I'm going to try to get it working on my system.

Jan

[Jan Jansen]

Dear Arjan,

It works, I'm happy!

However, it was necessary to install lynx and supplement the crontab with sudo bash


Regards,

Jan

[athoopen]

Glad it works, enjoy!! Sorry that I didn't mention installing lynx and add a line to the cron.

[mvveelen]

Nice work!

Thanks for sharing the script, although I prefer it to be a dzVents script or something like that. Not really a fan of using another directory like /usr/local/bin instead of the scripts folder and editing a cron separately to run it.

[EdwinK]

Thanks for sharing this. Was looking for something that alerts on pollen. Just hope that someone someday will create it with just one script, instead of going through the shell and crontab.

[EdwinK]

After this weekend, I'm going to take a look at why it doesn't work for me.


edit: Finally I got it. Had to use sh hooikoorts to get the data.

[Kedi]

I am interested in a pollen device. Will you explain to me how you achieved that? Do you want to share the script used?

There is a nice site with an API which spits out JSON which could be easy processed in dzVents
