**wemo**
Keeps track which WeMo switches are in the network, their state and allows you to control them.
**switch**
Keeps track which switches are in the network, their state and allows you to control them.
Registers services `wemo/turn_on` and `wemo/turn_off` to turn a or all wemo switches on or off.
Registers services `switch/turn_on` and `switch/turn_off` to turn a or all switches on or off.
Optional service data:
- `entity_id` - only act on specific WeMo switch. Else targets all.
- `entity_id` - only act on specific switch. Else targets all.
**device_sun_light_trigger**
Turns lights on or off using a light control component based on state of the sun and devices that are home.
