Doorbells

You have definitely used doorbells many times! In what way is this a product for smart homes? Wireless doorbells that communicate via 433MHz can, of course, send out sound signals like their completely normal counterparts. The difference is that they can also communicate with other devices in your automated home. For example, they can receive signals from motion sensors and magnetic contacts. This means that you can set up your doorbell to trigger other actions in your smart home, such as turning on lights or sending a notification to your phone when someone rings the doorbell.
