# 3. Push Notifications

Push notifications keeps users informed in real time. It can include security alerts (unlocked doors, movement detection) and maintenance reminders (air filter changes, water leak warnings).

Your mobile app development company can integrate customizable notification sounds. So, users will know whether it’s an urgent security issue or just a routine update without opening their smart home automation app.

# 4. Customizable Scenarios

If your app supports centralized control of multiple devices, you can implement grouping features. This allows users to control multiple devices with a single command.

For example, with a single tap, a “Good Night” mode locks doors, turns off lights, and lowers the thermostat.

You can also offer pre-made group templates for different rooms (e.g., living room, kitchen) if you have enough compatible devices. If not, allows user to set groups for their needs.

# 5. Schedule Timers

This feature is similar to the previous one. It allows users to pre-set routines, like turning on outdoor lights at sunset or adjusting indoor temperatures before bedtime. This way, users will have one less thing to worry about.
