This MiOS plugin interfaces with devices in the ​Belkin WeMo range.

Supported devices

• ​WeMo Switch: an appliance switch.
• ​WeMo Motion: a motion sensor.

Supported devices are recognized by the plugin and are presented in the dashboard as a child device.

Unsupported devices

• ​WeMo Baby: a remote microphone.

Unsupported devices will not be recognized by the plugin.

WeMo technology

WeMo devices use 2.4 GHz Wi-Fi to connect to your LAN and the Internet. On the LAN, WeMo devices are visible as ​Universal plug-and-play (UPnP) devices. The MiOS plugin acts as a UPnP control point specialized to communicate with WeMo switches and sensors. WeMo devices also operate an external secure tunnel to Belkin's own servers to permit remote control through the iOS app. This is a separate protocol to UPnP, not spoken by the MiOS plugin.

Prerequisite setup

You will need the official Belkin ​WeMo app for iOS to set up new WeMo devices and add them to your Wi-Fi network. You will also need the app to upgrade WeMo firmware. For day-to-day use you do not need the iOS app at all.

Set up all your WeMo devices with the iOS app before installing the MiOS plugin. It is recommended that you assign a fixed IP address to each WeMo device using your router's DHCP Reservation feature; this will help the MiOS plugin to re-establish connections to the devices more quickly and reliably when it starts.

If you want to interface with If This Then That ​IFTTT, register an account with IFTTT and set up your rules.

Installing the plugin

Install the plugin from ​apps.mios.com. If you have WeMo Motion sensors, or want to receive instant status updates in the dashboard when a switch is changed through the iPhone app or ​IFTTT, also install the ​UPnP Event Proxy plugin. (Note that the UPnP Event Proxy has ​extra uninstallation steps.)

Discovering WeMo devices

On the plugin's main device, click the spanner/wrench and go to the Configure tab. Ensure that the Enable scan for WeMo devices on LAN option is turned on.

The Configure page lists all of the WeMo switch and sensor devices that were found on your LAN. (Note that sometimes a device will not respond to discovery. Reload the Luup engine and the plugin will attempt discovery again. Devices on different subnets will not be discovered.)

For each device that you want Vera to know about, press one of the Add buttons. Press Add Static if you allocated that WeMo device a fixed IP address through your router; press Add Dynamic otherwise.

Once you have added all devices, close the device dialog and press SAVE.

On restarting the Luup engine, child devices will appear for each WeMo device. You can rename these and place them in rooms.

Removing devices

To remove a WeMo device, go to the Configure page and press Remove for the devices that you want to remove. Close the device dialog and press SAVE.

Controlling devices

Child devices follow the same conventions as other MiOS switches and sensors.

WeMo switches

Switches show their on/off status in the dashboard. Clicking On or Off will change the state.

Service variables:

Namespace	Variable name	Meaning
urn:upnp-org:serviceId:SwitchPower1	Status	0 if switch is off; 1 if switch is on

Actions:

Namespace	Action name	Parameters	Meaning
urn:upnp-org:serviceId:SwitchPower1	SetTarget	newTargetValue: 0 to turn switch off; 1 to turn switch on	Set the switch to the specified state

Events:

Name	Meaning
A device is turned on or off	The switch status has changed from on to off, or from off to on

WeMo sensors

Sensors show their tripped status in the dashboard. Clicking Arm or Bypass affects only the Vera internal state; it has no effect on the WeMo sensor and will not affect whether WeMo rules fire.

Service variables:

Namespace	Variable name	Meaning
urn:micasaverde-com:serviceId:SecuritySensor1	Tripped	0 if no motion detected; 1 if motion was detected in the last 2 seconds
urn:micasaverde-com:serviceId:SecuritySensor1	Armed	0 the sensor is bypassed; 1 if the sensor is armed

Actions:

Namespace	Action name	Parameters	Meaning
urn:micasaverde-com:serviceId:SecuritySensor1	SetArmed	newArmedValue: 0 to bypass the sensor; 1 to arm the sensor	Set the sensor's arm/bypass state

Events:

Name	Meaning
A sensor (door/window/motion/etc.) is tripped	Fires when motion is detected
An armed sensor is tripped	Fires when motion is detected and the sensor is armed
