wemo component is the main component to integrate various Belkin WeMo devices with Home Assistant.
Supported devices will be automatically discovered if the optional
discovery configuration item is omitted or set to true or if the
discovery component is enabled. If the
discovery configuration item is set to false, then automatic discovery of WeMo devices is disabled both for the
wemo component and for the
discovery component. Loading the
wemo component 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
# 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.
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
