What the app does

AutomationPut your AC or geyser on an auto-off timer that fires even from the wall switch, add daily schedules and countdown timers, and include it in whole-home routines and scenes.

SafetySafe Mode disconnects your heavy appliance above 280V or below 200V — important protection for an AC or geyser. Lock Room sends WhatsApp alerts, and it runs offline.

MonitoringLive power monitoring shows real-time voltage, current, wattage, units consumed (today, this week, this month) and power factor. When power factor drops below 0.8 the switch sends a servicing alert before your appliance fails — plus running hours and full ON/OFF history.

ConvenienceSwitch your AC or geyser with Siri, Google or Alexa, trigger it with an NFC tap, or add a one-tap home-screen shortcut.
