3. Inconsistent Automation: Check schedules and rules in your smart home app to ensure they’re correctly configured.

Frequently Asked Questions

Q: How do I control multiple devices with one voice command?

Set up routines or scenes through the smart home hub’s application, allowing you to control several devices simultaneously by saying a single phrase.

Q: Can I use my smartphone as a hub instead of dedicated hardware?

Yes, many apps like HomeKit and Google Home can act as hubs if your phone is always connected to Wi-Fi. However, for better performance in areas with poor signal or when you leave home, a standalone hub might be necessary.

Q: What happens if my internet connection goes down?
