IoT and AutoIt

[gladiator]

I'm trying to control my IoT devices through http commands through an AutoIt script. The toggle command does work with devices with Tasmota fw but unfortunately it works only the first time I issue the command with shelly 1 devices (i.e. if the device is ON and I run the script though the gui the device goes OFF the first time, it stays in OFF state the following times). You find here the script.

If I run without GUI the only statement

InetRead ( "http://192.168.0.33/relay/0?turn=toggle" )

It work flawlessly. Do you have any suggestion/hint for a solution or for proceeding in a debug ?

#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("Form1", 615, 438, 192, 124)
$Label1 = GUICtrlCreateLabel("Prova shelly", 271, 64, 73, 17)
GUICtrlSetFont(-1, 8, 800, 4, "MS Sans Serif")
$Label2 = GUICtrlCreateLabel("Abatjour", 287, 152, 40, 17)
$Button1 = GUICtrlCreateButton("Button1", 270, 176, 75, 25)
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $Button1
            InetRead("http://192.168.0.33/relay/0?turn=toggle")
    EndSwitch
WEnd

Have you tried using the Force Reload option?

InetRead("http://192.168.0.33/relay/0?turn=toggle", $INET_FORCERELOAD)

Yessssssss, Danp2, thanks a lot: that made the magic !!!!!! I appreciate VERY MUCH your prompt and effective support.

May I try to ask an additional question ? Do you have an idea why this additional parameter is not needed with IoT devices with Tasmota fw and is mandatory with shelly devices ?

Prolly because Tasmota has something along the lines of:

<meta http-equiv=“Pragma” content=”no-cache”>
<meta http-equiv=“Expires” content=”-1″>
<meta http-equiv=“CACHE-CONTROL” content=”NO-CACHE”>

in its page, which won’t go to the cache.

Thanks JockoDundee !!!

As an aside, does Tasmota support JSON and MQTT?

Just asking as I know the answer, but it might send you down an interesting rabbit hole....
