---------------

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/

```bash
curl --header "Content-Type: application/json" \
--request POST \
--data '{"command":"test_local","state":1,"action":""}' \
http://127.0.0.1:5000/esp/
```

> testing /control/?args

```bash
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:
```url
http://192.168.1.252/esp/ArgToDB/?device_key=&command=&value=
```

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
