Smart WiFi Intelligent Switch can be used in any application up to 63A (14.5kW) and also accurately measure the power consumption. Can be used to make any home, office or factory ‘Smart’ while monitoring the amount energy used.

Device Protection: Protect your high value devices from surges due to fluctuations caused by loadshedding . This is achieved by setting thresholds for Over and Under voltages. The unit will remain in the OFF state should these thresholds be exceeded.  The units will constantly monitor the mains input / utility power levels (from Eskom) and will only switch ON once the voltage is within the thesholds you set.

Recommended Upper voltage 240VAC / Lower voltage 220VAC, meaning this device will only switch ON if the voltage is between 220 to 240VAC and will switch OFF if the voltage falls outside the preset limits. These thresholds are fully adjustable for both voltage and current via the units front panel or via your mobile phone (recommended method with free Tuya app installed).

Control (ON/OFF) any device remotely via your phone from any location (free Tuya app). Allows for ‘smart switching’ and includes a safety trip switch for over and under voltage and earth leakage.

Simply, ‘*Wire, Configure and Play’.


  • Single Phase 230VAC 50/60Hz up to 63A or 14.5Kw.
  • IMPORTANT NOTE: DO NOT replace your existing Earth Leakage breaker as this unit only switches the Live ON and OFF (not an isolator). Setting this smart unit to a lower value (than your fixed value existing unit) can often result in only the smart unit tripping first.
  • Typically installed after your DB’s Main Isolator and Earth Leakage breakers (to measure total home consumption). Adjust to measure specific items only such as a geyser or pump etc.
  • Can be used as smart 1st trip when set a lower value then your existing Earth leakage which is typically 30ma (0.03A). Unit has a 30sec monitor timer after each trip. If the over voltage, under voltage, over current or earth leakage is still present the unit will not reset.
  • This Switch supports DIN rail Mounting. For Samite Breaker connections you will need an adaptor [click here]
  • This Switch supports Energy or Consumption Monitoring (1200imp/kwh)
  • Requires an adequate WiFi signal to operate.
  • Via easy Smart Functions this switch can be linked to smoke or any other detectors to disconnect the mains feed etc.
  • *qualified Electrician is required.

Home Automation made Smart, Simple and Affordable via the Tuya, SmartLife App (Android or IOS),  offering the fastest, most stable platform and widest range of Smart Products. Supports Alexa, Google Home and IFTTT.

Great way to make any appliance or device, ‘Smart’.

Product Features


  • Remote control at anytime from anywhere
  • Schedule/Timer/loop timer
  • Energy consumption monitoring & reporting / real time electricity usage and power
  • Electric leakage protection:10-99mA (feature can be disabled). Trips the L only. Apply 20mA to circuits that may trip on on your DB @ 30mA. Useful to ensure a trip does not require a manual reset. Timer counts 30 seconds after each trip and will only reset once the leak is cleared.
  • Preset current/voltage threshold values by app, once the real-time/current/voltage reaches the threshold values, the connected electrical appliances will be automatically turned off
  • Smart (mobile Phone) & LCD display, real-time display voltage, current, power, total energy kWh
  • Under voltage protection 90V-210V (adjustable)
  • Over voltage protection 230V-300V (adjustable)
  • Over current protection 1A-63A (adjustable) (default: 63A)
  • Activation dates, days of the week, start time and duration can all be pre-configured via the Smartlife application giving you complete remote control and ON/Off overwrite.
  • Supports Voice Commands and also AI units such as Amazon Alexa Echo and Google Home solution.
  • All your Smart Devices connected via a Single stable Platform been the Smart Life app from Tuya.
  • The entire SmartLife system performance replies on an ‘adequate WIFI’ (2.4GHz only) signal.


Typical Uses (but not limited too)

  • Protect high value voltage sensitive equipment such as inverters, servers, hifi, TV, home theatres etc.
