Q about dzVents syntax versus LUA

[BartSr]

Hi!
In a LUA script i have next (working) code:

Code: Select all

             commandArray[1] = {['OpenURL']="http://192.168.2.56/cm?cmnd=Power%20On" }
             return commandArray

This switches on a light in a Tasmota-flashed wifi switch.

Anyone who can advise me about the dzVents equivalent?

Thanks!

Wat is the trigger of this script?
Either way the Wiki describes it pretty nicely: https://www.domoticz.com/wiki/DzVents:_ ... d_handling

Thanks a lot jvdz, I overlooked this, maybe because of the the trailing get part.
I do succesfull

Code: Select all

domoticz.openURL({
            url = "http://192.168.2.56/cm?cmnd=Power%20On" ,
     --       method = 'GET',
     --       callback = 'energyRetrieved'
            })

Now I have another Q:
I do check if a device is alive using command:

Code: Select all

ping_success=os.execute('ping -c1 -w1 ' .. "192.168.2.200")

But I was advised this is not reliable due to the fact the device can be busy while pinged.
So I should ping several times with timedelay.
Now my Q: Can I give ping-command which will be delayed executed 3 times in sequence?

Thank you.

Just change the parameters on your ping command to try multiple times. Guess that would be the easiest?
...but you can also try it multiple times with an loop.
The thing to remember is that you will hold up the eventsystem in case your script takes seconds to process all of this.
