For example, a household could create a routine that adjusts lighting when rooms become unoccupied or modifies thermostat settings according to a predefined schedule.

Automation should be designed around predictable household needs rather than simply adding more automated actions.

Energy Alerts and Notifications

Smart energy systems can generate notifications when certain conditions occur.

Examples include:

• Unusually high electricity use

• Equipment operating for an extended period

• Temperature changes

• Device connectivity problems

• Battery status changes

• Solar-generation changes
