Smart geyser control
Your geyser, on your schedule
Your geyser is one of the biggest electricity users in your home. A remote geyser switch lets you heat water only when you need it: before the morning shower, after work, or while the solar is producing. Switch it off from anywhere when you're away.
- Remote on/off from a phone app, from anywhere
- Schedules and timers so hot water is ready when you need it
- Automation to keep the geyser off during peak times
- Works for other loads too: pool pumps, heaters and lights

Remote control for your rentals

How it works
The Astute device on your geyser connects to your Wi-Fi router and the CBi cloud platform. Your phone reaches it through the app, at home or away.
What is a remote geyser switch?
A smart switch fitted to your geyser circuit that lets you turn the geyser on and off, set schedules and timers from a phone app, from anywhere with an internet connection.
Will a smart geyser switch save electricity?
A geyser is usually one of the biggest users of electricity in a home. Heating water only when you need it, instead of keeping it hot all day, cuts wasted energy. How much you save depends on your household.
Which remote geyser switch should I choose?
The Astute Smart Controller fits inside your DB board; the Astute Smart Isolator replaces the geyser isolator on the wall. Our electricians recommend the right one after seeing your setup.
Can landlords control geysers in several rental units?
Yes. Each unit's geyser gets its own smart switch, and you can see and control them all from the app, which is ideal for rentals, Airbnbs and holiday homes.
Does the switch need Wi-Fi?
Yes. The Astute devices connect through your Wi-Fi router to the cloud platform, which is how the app reaches them when you're away from home.
Is installation certified?
Yes. The switch is installed by a registered electrician on your geyser circuit, and the work is certified.
