## Short Description
The Shelly 3EM-63 Gen3 is a compact energy meter designed to monitor either a three-phase system or three independent single-phase circuits. It can operate standalone within a local Wi-Fi network or be integrated into cloud-based home automation services via MQTT, HTTP, and WebSocket. All inbound connections support TLS encryption.
The device provides real-time monitoring of accumulated energy, as well as instantaneous voltage, current, active power, and apparent power per phase. Data is stored in non-volatile memory and can be retrieved for up to 7 days at 1-minute intervals.
Equipped with a real-time clock, the device maintains accurate timestamps even if the connection to an SNTP server is lost.
Remote access, setup, and monitoring are supported for users, while the device can also communicate with automation systems when both are on the same network infrastructure.
An embedded web interface enables users to monitor, control, and configure the device settings directly.
## Main Features
- 4-quadrant power measurement
- On-MCB mounting: above or below the circuit breaker (Shelly 3EM-63T Gen3 only)
- Supports multiple configurations: three-phase or single-phase installations
- Non-contact current sensing using current transformers (CTs)
- Phase sequence error detection (optional feature)
- No load threshold: 30 VA per channel
- Optical pulse output indicating energy consumption
- Real-time clock: ensures correct timestamps for stored data during internet outages
- Data logging: up to 7 days of 1-minute resolution data retention
- Accuracy Class B (IEC 62053-21)
- Photovoltaic (PV) ready
> **Notes:**
>
> ¹ Shelly 3EM-63T Gen3 only
> ² Phase sequence error detection uses zero-crossing analysis of phase voltages. A valid sequence is Phase A → Phase B → Phase C. If the detected sequence is Phase A → Phase C → Phase B, a `phase_sequence` error is reported when enabled.
> ³ When total load drops below 30 VA per channel, power is still measured but no energy is accumulated. A "No load threshold" notification appears in the web interface and mobile app.
> ⁴ In case of internet or network interruption, the built-in RTC maintains accurate timekeeping for recorded data.

## Short Description
The Shelly Pro 3EM is a DIN rail-mountable three-phase energy meter. Enhanced with full `gen2` firmware flexibility and LAN connectivity, it offers professional integrators expanded options for end-customer solutions. It can operate standalone in a local LAN or Wi-Fi network, or be managed remotely via cloud-based home automation services using MQTT, HTTP, and WebSocket protocols. All inbound connections support TLS encryption.
The device provides real-time measurements of accumulated energy, as well as instantaneous voltage, current, active power, and apparent power per phase. Data is stored in non-volatile memory and can be retrieved for up to 60 days at 1-minute intervals.
It features a built-in real-time clock (RTC) to maintain accurate time even if the connection to an SNTP server is lost.
Users can remotely access, configure, and monitor the device, while the device can also communicate with automation systems—provided both are within the same network infrastructure.
An embedded web interface enables monitoring, control, and configuration of device settings.
