Dealing with unreachable devices.

Lights are a shared, physical device and each light maintains its own persistent connection to LIFX servers. That means individual lights may respond differently to each other. Reasons may include being physically powered off or being unreachable over the internet. When LIFX detects that a light is unreachable it marks it as offline. The light returns to normal after reconnecting to LIFX servers.

Clients can use the status of each light to determine corrective action. Generally it's easiest to make the request again, except when performing effects. Effects are visually loud and extra care should be taken to prevent disturbing the user.

Statuses are returned in the response body from endpoints that perform actions on lights.
