Belkin WeMo

The Belkin WeMo integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] is the main integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] to integrate various Belkin WeMo devices with Home Assistant.

There is currently support for the following device types within Home Assistant:

Binary sensor (Belkin WeMo Motion Sensor)
Fan (Belkin WeMo (Holmes) Smart Humidifier)
Light (Belkin WeMo LED lights and Smart Dimmer Switch)
Switch (Belkin WeMo Switches and includes support for WeMo enabled Mr. Coffee smart coffee makers.)

Configuration

Configuration Variables

Looking for your configuration file?

discovery boolean (Optional, default: true)

Setting this value to false will prevent the automatic discovery of WeMo devices by the WeMo platform and the discovery platform (static devices will still be discovered)

static list (Optional)

One or more static IP addresses for WeMo to use

Supported devices will be automatically discovered if the optional discovery configuration item is omitted or set to true or if the discovery integration is enabled. If the discovery configuration item is set to false, then automatic discovery of WeMo devices is disabled both for the wemo integration and for the discovery integration. Loading the wemo integration with the discovery configuration item omitted or set to true will scan the local network for WeMo devices, even if you are not using the discovery integration.

# Example configuration.yaml entry with automatic discovery enabled (by omitting the discovery configuration item)
wemo:

# Example configuration.yaml entry with automatic discovery enabled (by explicitly setting the discovery configuration item)
wemo:
  discovery: true

Alternately, WeMo devices that are not discoverable can be statically configured. If you have WeMo devices on subnets other than where Home Assistant is running, or devices in a remote location reachable over a VPN, you will need to configure them manually. Statically configured devices may be used with or without automatic discovery enabled. Example static configuration:

# Example configuration.yaml entry with automatic discovery disabled, and 2 statically configured devices
wemo:
  discovery: false
  static:
    - 192.168.1.23
    - 192.168.52.172

Note that if you use static device entries, you may want to set up your router (or whatever runs your DHCP server) to force your WeMo devices to use a static IP address. Check the DHCP section of your router configuration for this ability.

If the device doesn’t seem to work and all you see is the state “unavailable” on your dashboard, check that your firewall doesn’t block incoming requests on port 8989, since this is the port to which the WeMo devices send their updates.

Device options

Selecting the Configure button on the WeMo integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] will bring up some additional options that can be configured for WeMo devices.

Device Options

Subscribe to device local push updates: WeMo devices support both the Local Push and Local Polling IoT classes. Home Assistant will default subscribe to event notifications from WeMo devices and use the Local Push IoT class. If the Local Push doesn’t work, Home Assistant will use Local Polling as a fallback. Some devices are known not to work well with Local Push. WeMo devices expect to be on the same subnet as Home Assistant and will not work with Local Push otherwise. For devices known not to work with Local Push, the Subscribe to local push updates option can be disabled to force only Local Polling to be used.

There are some downsides of disabling Subscribe to device local push updates:

The WeMo Motion detector will not work in Home Assistant when Subscribe to device local push updates is disabled. The same will be for the sensor on the WeMo Maker device. Without a push subscription, Home Assistant will be unaware of motion events.
Long press events, when the button on a wall switch/dimmer is pressed, will not work if Subscribe to device local push updates is disabled.
Automations based on the device being locally switched on or off will be delayed by at least the polling interval (below).

Register for device long-press events: WeMo wall switches and dimmers will notify Home Assistant when the button on the device is held for more than 2 seconds. This feature is enabled by default in Home Assistant (see below). If this feature causes issues for your device, it can be disabled by deselecting the Register for device long-press events option.

Emulated devices

Various software that emulate WeMo devices often use alternative ports. Static configuration should include the port value:

# Example configuration.yaml entry with static device entries that include non-standard port numbers
wemo:
  static:
    - 192.168.1.23:52001
    - 192.168.52.172:52002

Fan

The wemo platform allows you to control your Belkin WeMo humidifiers from within Home Assistant. This includes support for the Holmes Smart Humidifier.

WeMo devices are automatically discovered if the discovery integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] is enabled.

Attributes

There are several attributes which can be used for automations and templates:

Attribute	Description
`current_humidity`	An integer that indicates the current relative humidity percentage of the room, as determined by the device’s onboard humidity sensor.
`fan_mode`	String that indicates the current fan speed setting, as reported by the WeMo humidifier.
`filter_expired`	A boolean that indicates whether the filter has expired and needs to be replaced.
`filter_life`	The used lifetime of the filter (as a percentage).
`target_humidity`	An integer that indicates the desired relative humidity percentage (this is constrained to the humidity settings of the device, which are 45, 50, 55, 60, and 100).
`water level`	String that indicates whether the water level is Good, Low, or Empty.

Actions

There are several actions which can be used for automations and control of the humidifier:

Action	Description
`set_speed`	Performing this action sets the fan speed (entity_id and speed are required parameters, and speed must be one of the following: off, low, medium, or high). When selecting low for the speed, this will map to the WeMo humidifier speed of minimum. When selecting high for the speed, this will map to the WeMo humidifier speed of maximum. The WeMo humidifier speeds of low and high are unused due to constraints on which fan speeds Home Assistant supports.
`toggle`	Performing this action will toggle the humidifier between on and off states.
`turn_off`	Performing this action will turn the humidifier off (entity_id is required).
`turn_on`	Performing this action will turn the humidifier on and set the speed to the last used speed (defaults to medium, entity_id is required).
`wemo.set_humidity`	Performing this action will set the desired relative humidity setting on the device (entity_id is a required list of 1 or more entities to set humidity on, and target_humidity is a required float value between 0 and 100 (this value will be rounded down and mapped to one of the valid desired humidity settings of 45, 50, 55, 60, or 100 that are supported by the WeMo humidifier)).
`wemo.reset_filter_life`	Performing this action will reset the humdifier’s filter lifetime back to 100% (entity_id is a required list of 1 or more entities to reset the filter lifetime on). Call this action when you change the filter on your humidifier.

Long press events and triggers

For WeMo Light Switches and Dimmers, pressing the button on the device for two seconds will activate a long press event. The long-press can trigger an automation either by using an event trigger or a device trigger. For an event trigger the event_type will be wemo_subscription_event. The event data will have a type parameter set to the value LongPress and a name parameter indicating the dimmer or light switch that was triggered.

The following is an example implementation of an automation:

# Example automation
- id: long_press_living_room
  alias: "Toggle amplifier power"
  triggers:
  - trigger: event
    event_type: wemo_subscription_event
    event_data:
      type: LongPress
      name: Living Room
  actions:
    - action: media_player.toggle
      target:
        entity_id: media_player.amplifier

A device automation can also be used through the automation editor. Look for the Wemo button was pressed for 2 seconds trigger for the dimmer or light switch device.

Note: Due to the way that long press events are received by Home Assistant, modifying any of the Rules through the WeMo app can cause long press events to stop working until Home Assistant is restarted. Home Assistant modifies the local device’s rules database to enable long press event support. This local modification is not synchronized with the cloud service. Any rule changes from the cloud service (via the app) will likely overwrite the local changes made by Home Assistant.
