ESP-01 devices have two active pins - Led output (GPIO 2) and Switch (GPIO 0)

Connect those pins in a correctly by schematics and record ESP's ip-address. Add ip address to a database of python server app. Send JSON command to a linux server and let him execute the rest thing.

Compile and run the ESP8266 microprocessor code

check ip addresses to be used check devices and device commands

API Testing commands

teting /control/

curl --header "Content-Type: application/json" \
	--request POST \
	--data '{"command":"test_local","state":1,"action":""}' \

testing /control/?args

curl --header "Content-Type: application/json" \
	--request POST \
	--data '{"command":"test_local_json","pins":[{"command":"switch_mirror","action":"1"},{"command":"switch_AI","action":"activate"}]}' \
	http://127.0.0.1:5000/esp/JsonToArg/

Browser Get request to raspberry for test:

http://192.168.1.252/esp/ArgToDB/?device_key=<device_key>&command=<sensor_command>&value=<value of water, example 112>

PIR sensor workflow

The command that sensor sends from controllino to raspberrypi

http://192.168.1.252:5000/esp/ArgToDB/?command=pir_sensor&device_key=ESP_ARDU_MASTER&isMaster=1&action=0

action should change here

The command that triggers the mode of pir work

curl --header "Content-Type: application/on" --request POST --data '{"command":"pir_led_selector_command","state":0,"action":""}' http://192.168.1.252:5000/esp/JsonToArg/

If you change state to 1, Then pir will work
