IoTClient is an Internet of Things client - it can be used as a client for any type of HTTP-(GET/PUT/POST) (REST) controllable device like garage doors, window blinds, light switches, TV-, audio- or other home entertainment devices. As well as to fetch values from sensors like door sensors or weather stations.

It is currently designed to control up to 4 different devices. Every device can be controlled with 6 actions.

How to configure: 
      Devices and actions must be configured with the help of your Garmin Connect smartphone or desktop app .
      Start your Garmin Connect Smartphone App. Connect your Garmin device via bluetooth. Go to more - Garmin devices - select your device - Connect IQApps -- Widgets - IoTClient - Settings
      Device 1 Name: is the name of the device 1 (sample: GARAGE DOOR )
      Device 1 action 1 URL: is the URL which triggers the 1st action of the first device (sample: http://192.168.1.1/garagedoor/open)
      Device 1 action 1 Name: is the name or short description of the first action of the first device (sample: „OPEN“)
      Device 1 action 1 JParam: is the Json parameter name that will be displayed after doing the request. If left blank, the response status will be displayed instead

      If you want to disable a device or an action just leave the appropriate name field blank!

      Parameter "switch to next action automatically" controles the widget behaviour. If checked, every time a action was fired, the widget will switch to the next action automatically. (good for window blinds or garage doors) If not checked, you have to switch to the next action by double click/double tap manually. (good for volume control or TV channel switches)

    To send a JSON PUT just add the JSON as URL parameter to your to your action URL.
    Parameter name must be json_put or json_post.

    Example: http://bridge IP address/api/lights/..../state?json_put={on:true, sat:254, bri:254,hue:10000}

How to use:
      
    Start the widget by pressing up or down until IoTClient widget is displayed. 
    
    If the lines above and below the texts is green, BT connection is running. If red, check your BT connection!
      
      Push Start/Stop (or tap screen on touch screen devices like vivoactive) to trigger the current action. If "auto-switch action for device" is checked the widget will switch to the next action automatically.

      Double-Push Start/Stop (or double-tap screen on touch screen devices like vivoactive) to switch to the next action without triggering the action.

      Push menu (hold UP) to switch to the next device.
