[Solved] $LedColor.color execute without hex color sign #

---

Hi
I’m searching how to get a url without # sign with the hex var $LedColor.color.
For my program i have to use

if 
$LedColor.color changes
then
execute "wget -q -O /dev/null \"http://192.168.3.201/?color=%23$LedColor.color\""

My device needs %23 now it gets %23#FFFFFF but i want %23FFFFFF without the # sign

I think the are functiuns for variable manipulating but i can’t find them wright now after hours of searching.

Thnks

What happens if you try it like that
if $LedColor.color changes then execute "wget -q -O /dev/null 'http://192.168.3.201/?color=%23$LedColor.color'"

@sjaak538 I don’t think pimatic provides a suitable function to manipulate the variable as required for your case, however you can use the “sed” system command to do it:

execute "wget -q -O /dev/null  \"http://192.168.3.201/?color=%23\"`echo \"$LedColor.color\" | sed 's/#//'`"

Yes that’s it, now it is working great.
I fiddled a little with sed command but i’m getting crazzy with all the ’ ,`, ", and the "

Thanks a lott

You’re welcome. I am happy, that it is working fine for you now. You’re right, btw, using all these quotes is hell!

Maybe for other users
This works nice

Good luck

uhh that looks great, i think it is the behavior is was looking for the lasst couple of days to implement my ESP8266 Ikea Dioder. It also gets the color value with an websever on the ESP, i will try this. I hope it will work. Would be a great way to implemt mit ESP easily into pimatic and my HomeKit system

Thanks for that

@sjaak538 Thanks for sharing this project.
Looking something like this with MQTT. So far the closest to my idea is https://github.com/sticilface/Melvanimate.
Maybe I’ll do MQTT support for this project.
Button you’re probably too, but I give to others.

    {
      "buttons": [
        {
          "id": "off",
          "text": "Off"
        },
        {
          "id": "cylon-chaser",
          "text": "Cylon Chaser"
        },
        {
          "id": "rainbow",
          "text": "Rainbow"
        }
      ],
      "id": "neopixel",
      "name": "Neopixel",
      "class": "ButtonsDevice"
    }

example corresponding rule

    {
      "id": "neopixel-off",
      "name": "Neopixel off",
      "rule": "when Off is pressed then execute \"wget -q -O /dev/null http://10.0.0.99/L4?v=1\"",
      "active": true,
      "logging": true
    },
    {
      "id": "rainbow",
      "name": "Rainbow",
      "rule": "when Rainbow is pressed then execute \"wget -q -O /dev/null http://10.0.0.99/L7?v=1\"",
      "active": true,
      "logging": true
    },
    {
      "id": "cylon-chaser",
      "name": "Cylon Chaser",
      "rule": "when Cylon Chaser is pressed then execute \"wget -q -O /dev/null http://10.0.0.99/L9?v=1\"",
      "active": true,
      "logging": true
    }

Yes this is nice and works perfect.
Simple cheap and easy

small detail when=if in the rule

I forgot to write it, it’s for Pimatic 0.9

I forgot to write it, it’s for Pimatic 0.9

If use “if” instead of “when” it should work with pimatic 0.8. Pimatic 0.9 has not been released yet.

@sjaak538 Hello Sjaak,
would you like to share your Arduino code? I seem unable to get the colorcode passed to the ESP
