Hosts a REST Server on an ESP32 to set variables of different types. Compatible with openHAB HTTP Binding.

Features:

• Optional automatic storage of data in EEPROM
• Automatic WiFi reconnect
• Easily controlled through a simple REST interface

Available Prop types:

• Boolean
• Float
• Int
• Color
• String

To read values you need to send an HTTP GET request to /get/propname. You can easily do this in your browser (navigate to http://devicename/get/propname) or via Postman.

To write values you need to send an HTTP PUT request to /set/propname. This is done most easily via Postman, where you can put the data to be set in the "Body" settings with the type set to "raw".

1. Install HTTP Binding
2. Add new HTTP thing with baseURL http://devicename/ where devicename is the wifiHostname specified in your ESP32 sketch
3. Go to the "Code" tab and set up the commandMethod PUT and your desired channels, as shown in this example (* means don't change):

UID: *
label: *
thingTypeUID: http:url
configuration:
  baseURL: *
  refresh: 10
  commandMethod: PUT
channels:
  - id: brightness
    channelTypeUID: http:dimmer
    label: Brightness
    description: ""
    configuration:
      stateExtension: get/brightness
      commandExtension: set/brightness
  - id: power
    channelTypeUID: http:switch
    label: Power
    description: ""
    configuration:
      stateExtension: get/power
      commandExtension: set/power
      onValue: ON
      offValue: OFF
  - id: color
    channelTypeUID: http:color
    label: Color
    description: ""
    configuration:
      stateExtension: get/color
      commandExtension: set/color
      colorMode: RGB

This example is compatible with the "simple" example sketch.
