WHY DUMLAB

NO INTERNET?
Still works.

Local Mode keeps every switch, fan and schedule running entirely on your home network — no ISP, no outage, no delay.

NO SUBSCRIPTION.
Own your devices.

No monthly fee to unlock features you already paid for. Firmware and control logic ship with the hardware, permanently.

MADE FOR INDIA.
230V hardware design.

Built and tested for Indian mains voltage, wiring conventions and switchboard depths — not adapted from a 120V import.

// APP

ONE APP. EVERY DEVICE.

Control, schedule and monitor every DUMLAB device from a single dashboard — synced locally first, cloud second.

  • REAL-TIME STATEReflects the device shadow, not a cached guess
  • SCHEDULES & SCENESRun on-device — survive an internet outage untouched
  • VOICE CONTROLGoogle Assistant & Alexa, routed through your own cloud
  • FLEET VIEWEvery home, every device, one login
