Cisco Meraki MT40 Smart Power Controller: Complete Product Description
The Cisco Meraki MT40 Smart Power Controller is a cloud-managed, in-line AC-powered device designed to provide remote visibility, monitoring, and control over the power consumption and status of connected equipment.
As the newest addition to the Meraki MT sensor portfolio, the MT40 integrates seamlessly with the Meraki platform, offering real-time data and remote management capabilities to minimize downtime, reduce energy costs, and streamline troubleshooting across distributed deployments.
It functions by being connected in-line with a device’s power supply, using Bluetooth Low Energy (BLE) to communicate wirelessly through compatible Meraki MR (Access Point) or MV (Smart Camera) devices, which act as gateways to the cloud-based Meraki dashboard.
Key Features and Benefits
| Feature | Description & Benefit |
|---|---|
| Inline Power Monitor | Provides continuous, real-time visibility (24/7/365) into the power consumption and status of the connected device. |
| Downstream Power Control | Enables administrators to remotely turn off, turn on, or cycle power to the connected device via the Meraki dashboard. This eliminates the need for on-site visits for simple troubleshooting and reboots. |
| Intelligent Alerting | Users can set granular alert thresholds on power metrics. Receive flexible notifications via email, SMS, mobile push, and Webhooks for anomalous power readings. |
| Centralized Cloud Management | Configure and manage the MT40 alongside all other Meraki devices from a single pane of glass—the Meraki dashboard. |
| Energy Optimization | Monitor energy usage (kWh) to benchmark consumption and use remote power control to save energy by turning off non-essential devices when not in use. |
| Secure Platform | Equipped with a Cisco Trust Anchor Module (TAm) for secure authentication and firmware image signing, preventing unauthorized communication. |
| Offline Data Logging | The device retains up to 3.5 hours of sampled power data if it loses connection to the gateway, ensuring data integrity when connectivity is restored. |

Common Use Cases
The MT40 is ideal for managing electrical equipment across distributed environments like retail, quick-service restaurants, education, and small businesses, or for supplementing existing infrastructure in larger enterprises.
- Remote Equipment Management: Remotely reboot Point-of-Sale (PoS) systems, printers, audio/video equipment, or digital signage without requiring on-site staff.
- Facility Monitoring: Control and monitor the power to lighting, fans, low-power HVAC units, and refrigerators.
- IT Infrastructure: Monitor power usage of servers, network devices, or when connected upstream of an existing “dumb” Power Distribution Unit (PDU).
