If the power is lost to all Casambi units in a network, then the time information will be lost too. The app needs to be reconnected to the network to enable the time information to be “reseeded” to the devices in the network. 


If just one Casambi-enabled device remains powered, it will retain the time information and will automatically “reseed” it to other devices in the network, when power is restored to them.


If there is no app connected to the network, the time in individual units may drift slightly over longer periods of time due to normal electronic component tolerances. It is recommended to periodically (e.g., every 6 months) reconnect the app to the network in order to refresh the time to all devices.


Time will resync when a mobile device running the app & with internet connection is connected to the network regardless of network access rights (User, Manager or Admin).
