os.execute.aftersec

[markjgabb]

is there a way to get a delayed os.execute working in dzvents atm i have the following

os.execute('espeak welcome-home').afterSec(20)
but it seems to ifnore the aftersec and just runs it instantly.....
also not sure how to make longer that one word arguments os the os.execute as it will only take one word at the moment

os.execute is an os function that is not managed at all by dzVents. So no, that's not working unfortunately. Maybe you can create some bash function with an internal delay and execute that instead from your script.

[markjgabb]

that sounds like a likely way to do it...simple and it works

Below is an example how it can be done. This specific example calls an url using curl on a linux platform. The important thing is to release the control back to Domoticz immediately.

Code: Select all

local delay = 5
local url = 'http://somwebsite.com'
os.execute('(sleep '..delay..';curl -s "'..url..'" > /dev/null)&')

We should not underestimate the importance of WAF for the future of home automation.

What is the reason you put this a the end: > /dev/null)&
I use os.execute as well but then just the URL :

Code: Select all

os.execute('curl "http://127.0.0.1:8081/json.htm?type=command&param=setcolbrightnessvalue&idx=3&hue=18&brightness=50&iswhite=false"')

os.execute('curl "http://127.0.0.1:8081/json.htm?type=command&param=setcolbrightnessvalue&idx=3&hue=18&brightness=50&iswhite=false"')

It's a redirection (discard) of the command output (not necessary) followed by the ampersand sign that will cause the command to run in the background. (prevents delays caused by waiting for the command to finish)

Your'e welcome. Don't forget the inner parenthesis which is crucial for it to work.

So it will look like this then

Code: Select all

os.execute('(curl -s  "http://127.0.0.1:8081/........iswhite=false" > /dev/null)&')

This should be enough when you don't need the separate sleep command:

Code: Select all

os.execute('curl -s "http://127.0.0.1:8081/json.htm?type=command&param=setcolbrightnessvalue&idx=3&hue=18&brightness=50&iswhite=false" &')

Using this in a Lua script to run multiple commands using os.execute, thanks!

Code: Select all

os.execute ('(/bin/sleep 4 && /usr/bin/curl -s "http://192.168.0.5:1880/hueapi?devicename=lightstripmainbathmirror&state=on&brightness=254&r=0&g=0&b=0&colortemp=351&transition=0.5")&')
