Smart relay
The universal, smart control option for your electrical devices – both flexible and convenient
The most flexible solution for smart switching
The smart switching relay is your universal all-rounder for smart switching: Garage doors, smart irrigation systems, ventilation systems, pumps, lighting or conventional sockets – the range of possible uses is virtually limitless.
Multifunctional use
The smart relay uses potential-free contact for switching a range of electrical devices – e.g. garage doors, pumps, garden irrigation systems, (gas) boilers, ventilation systems, sockets and lighting.
Flexible installation
The Bosch Smart Home relay is flexible to install behind existing wall switches and buttons or in junction boxes – and even outdoors in weatherproof installation boxes (e.g. IP66).
Individual operation
You can control the smart relay in a number of different ways – using the connected wall switch/button, by voice, using custom scenarios, automations and time programs, as well as remotely via app.
Applications
Make your garage door smart
A popular application area for the Bosch Smart Home relay is as a smart garage door opener.
Do you open your garage door manually using a switch and by remote control? With the smart relay, you can make your garage door smart and thus
- open and close it using the app or voice commands.
- When used in combination with the door/window contact II (plus), you can see whether the garage door is open or closed at any time, no matter where you are – and be reminded to close it if necessary.
- Integrate your garage door into Smart Home automations or scenarios. Example:
IF you activate your “Leaving home” scenario AND the door/window contact II (plus) on the garage door signals that it is still “open”, THEN close the garage door.
Create a smart irrigation system
Switching the lawn sprinklers on and off manually is a thing of the past! With your smart relay, you can make your garden irrigation system smart. Simply install it in a weatherproof installation box (e.g. IP66) and you can:
- Control the irrigation system by app or voice.
- View the status of the smart garden irrigation system at any time.
- Integrate your lawn sprinklers etc. in scenarios or automations. Example: IF it is sunrise, THEN switch the smart garden irrigation system on AND switch it off again after 30 minutes.
- Switch the garden irrigation system on and off automatically using a time program, which can be set individually for each day of the week.
Make your sockets smart
The Smart Home relay is one of two ways to make traditional electrical appliances smart:
- Option 1 – the flexible, moveable variant: Plug the smart plug compact into the appropriate socket to give you smart control of the power supply to the connected devices.
- Option 2 – the space-saving variant: Install the smart relay discreetly behind the socket to give you smart control of the power supply. This is also particularly practical for sockets that are hidden behind cupboards and sideboards.
Thanks to the integrated switching relay, you can now control the socket flexibly: when on the move, via the app or in the conventional way using the switch, using voice commands or a timer, as well as with custom scenarios and automations.
This also helps to save energy: Simply cut off the power supply to stand-by devices automatically at bedtime or when you leave the house – thus relieving the strain on the environment and your wallet.
Make the ventilation system in your new build smart
Your ventilation system provides fresh ambient air on a time-controlled basis – but wouldn’t it be handy to also be able to react spontaneously to poor air quality?
The Bosch Smart Home relay can make ventilation systems smart. All you need is a switch input for external control. Simply install the switching relay here and take advantage of the flexible control options, using the app, voice commands or automation.
Pro tip: Have your smart ventilation system switch on automatically as soon as your Twinguard measures an insufficient air quality value – until the value is back in the optimum range.
Making your (gas) boiler and electric heating smart
Your relay can also assist you with smart heating: The smart relay allows you to control your (gas) boiler or electric heating via app and using the room thermostat.
- Make your (gas) boiler smart:
Simply connect the Smart Home relay to your central heating system and select “Boiler” as the purpose of use. You will then be able to switch the (gas) boiler on/off using the app or room thermostat. - Make your electric heating smart:
Connect the switching relay to the electric heating (e.g. infrared heating) and select “Electric heating” as the purpose of use. This will enable you to switch the heating on and off remotely via the app.
