NodeMCU-SmartPowerStrip-v2

NodeMCU sketch to control a power strip

Startup

• Change pins and modify status_relay variable with same number of pins

  int relay[] = {0, 4, 5, 16};
  bool status_relay[] = {false, false, false, false};

Using

• To connect the device to the network visit: tzapu/WiFIManager

• API

  Description	Method	Endpoint	Body elements
  To start the action described in the body	POST	/ps	"action" and "pin"
  To receive the status of the relays	GET	/ps/status	-
  To receive the number of the relays	GET	/ps/get_relay_number	-
  To receive the type of device	GET	/get_type	-

• Supported actions

  Action	Description
  on	Turn on relay
  off	Turn off relay

• Examples

  • Request body for "/ps":

        {
          "action": "YOUT_ACTION",
          "pin": 2
        }

  • Response body for "/ps":

        {
          "msg": "SOME_MESSAGE"
        }

  • Response body for "/ps/status" (with 4 relays):

        {
          "relay_1": false,
          "relay_2": true,
          "relay_3": true,
          "relay_4": false
        }

    • true indicates that the relay is turned on, false indicates that the relay is turned off

  • Response body for "/ps/get_relay_number" (with 4 relays):

        {
          "number": 4
        }

  • Response body for "/get_type":

        {
          "type": "power_strip"
        }

Development

• Button to reset wifi

Notes

It is possible to use any relay module (1, 2, ..., n) only by changing the pins, adding or removing them, and the whole system will adapt automatically
