TL;DR

IoT energy management combines sub-metering, sensors, cloud analytics and control to deliver continuous optimisation. Typical payback: 6–18 months. Used by Enlog across 2,000+ sites spanning PG, hotel, mall, office, hospital and factory.

10 proven IoT energy management use cases

  • —Prepaid PG / co-living billing.
  • —HVAC load monitoring and set-point control.
  • —Chiller plant optimisation.
  • —DG fuel theft detection.
  • —Water motor automation.
  • —Power factor live tracking.
  • —Peak demand shedding.
  • —Solar self-consumption optimisation.
  • —Occupancy-based lighting automation.
  • —Continuous commissioning / audit-grade savings verification.

Frequently asked questions

Is IoT energy management secure?

Modern IoT platforms (including Enlog) use TLS-encrypted cellular links and role-based dashboards. Local data stays in India (data-residency compliant).

Can IoT replace my BMS?

For small / mid buildings, yes. For large hotels or hospitals with complex HVAC, IoT typically overlays the BMS to add analytics and control that legacy BMS lacks.

Prepaid electricity meter
A prepaid electricity meter lets tenants, PGs and co-living owners pay for power upfront — like a mobile recharge. Here's how it works, who needs it, and how to choose one.
Reduce PG electricity bill
PG electricity bills can eat 20–30% of revenue. Learn the exact playbook PG owners use to cut bills and recover 100% cost from tenants — fairly and automatically.
Smart vs traditional meter
Smart meters read, report and control electricity consumption remotely. Traditional meters only spin. Here's the full comparison for PG owners, offices and homes.
How to do energy audit
An energy audit maps every kWh your building consumes. Learn the 7-step professional audit process used for hotels, malls, offices, hospitals and factories in India.
Common area billing PG
Corridors, lifts, pumps, gyms — who pays? Learn the fair, transparent way PGs split common-area electricity bills among tenants using room-wise prepaid meters.
VRV/VRF billing
VRV/VRF systems serve many zones from one outdoor unit — billing each zone is tricky. Here's how modern IoT metering attributes VRV consumption per room or per tenant.
