Shelly 1 and AutoIt

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.

NB Given the differences with tasmota fw I believe it's a matter of devices and therefore this forum is the most appropriate to look for a solution

#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

Here is the compiled version

Thanks for your prompt reply.

If I understand right what you're saying I confirm that the http toggle commands for tasmota and for shelley are different:

tasmota: http://ip-address/cm?cmnd=Power%20Toggle

shelly: http://ip-address/relay/0?turn=toggle

I was pointed out that the former always works for tasmota devices

the latter works only the first time for shelley devices
