Make Domoticz read a GPIO pin

Hello,

I need some help writing a correct statement in Rules to make sure that a virtual switch in Domoticz follows a GPIO, or PCFGPIO, defined by some rules, e.g. Toggle, using json.
I tried the SendToHTTP command, but I can't find the correct json syntax to send the status of that GPIO to the Domoticz IP.
I want to do this to allow ESP8266 to make some autonomous GPIO decisions, simply then notifying them to Domoticz.

I hope I have explained.

Thank you.

Can you use the Domoticz MQTT controller?
Then please have a look at this here: https://espeasy.readthedocs.io/en/lates ... #p029-page

Thanks for the hint.
I was wondering if it were possible using a variable that follows the GPIO state in rules, then I sendtoHTTP the value of this variable to Domoticz.
If yes, which could be the correct syntax?

See the "monitor" command: https://espeasy.readthedocs.io/en/lates ... ernal-gpio

This will send an event as soon as the pin state changes, on which you can act in the rules.

I am using some Sonnofs like relays, which can be triggered by local push button, other ESP or from Domoticz and reports its actual status to Domoticz.
GPIO-0 local push button
GPIO-12 relay

From Domoticz it is switched with:
