The Ogemray SW40 smart switch allows immersion heaters or other large loads (up to 25A / 6000W) to be controlled by the Eleven Energy app. Built-in power metering means that you can see exactly what you are using.

Bluetooth connectivity allows the device to be quickly and easily added to the Eleven App. You can then set schedules, or allow excess solar to be dumped into the immersion when the battery is full.

Wiring is exceptionally easy - just wire the neutral and live of the immersion circuit to the device, then use the switched live terminal to control the immersion.
