Home Automation Relays
There are many cases where you want to have a device activate automatically based on a certain event or a trigger. In many cases. it is possible to create a network of devices based on a shared protocol, such as Z-Wave, Apple HomeKit, or If This, Then That (IFTTT). But you may encounter a device that isn't compatible with the protocol you are trying to build around. In some situations, you may be able to include the device into your network using a home automation relay. You will just need to make sure that the home automation relay device itself is compatible with the network.
By using a home automation relay, you may be able to include a device that would otherwise not be compatible with your smart home network and use it alongside your other connected devices for automatic operation and control. Automatic operation can refer to devices that activate based on a set schedule or with certain trigger events. You can also operate these paired devices remotely using an app on your phone. This is usually done using a smart platform such as Total Connect 2.0, Alarm.com or Apple HomeKit. The app you use will normally depend on the smart home protocol you are trying to build around.
It's fairly easy to think of situations where a smart home automation relay could accomplish what you are trying do pull off. The typical scenario is that you have a device that you want to include with your smart home network, but it isn't normally a "smart" device designed for use with automation. Additionally, plug-in devices are also not frequently used with relays, as you can just use a plug-in module to make them compatible. Instead, you will often see relays with devices that require electrical power through a hardwired connection. You might be surprised how often this comes up.
Hardwired sirens are an example of devices that are frequently used with smart home automation relays. Wired sirens normally connect with hardwired panels, and the panel has a trigger output to activate the siren during an alarm. You also need a power relay included in the wiring configuration to cut power to the siren after the alarm has been cleared. You may also need an external power supply to provide sufficient power to the siren. But if you want to use a wired siren with a wireless system, you might consider using a home automation relay. In this instance, the siren will wire in directly with the home automation relay. The relay will then communicate with the panel to serve as a bridge for the siren.
