If you lose power to a PSM, all of the electrical devices connected to the PSM will also lose power. When power is restored to that PSM, power will be restored to the connected devices. The devices will generally reset to the state at which they were running at the time of power loss.

In the event that Internet connection is lost, the system will continue to operate locally. This means that PSMs, hardware switches, motion sensors, and dimmers will all continue to function normally. Device settings and 'scenes' cannot be changed without an Internet connection and live logging data / remote support will be disabled. Once Internet access is restored, the system will resume full functionality.
