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.
