Who it fits
Good fit for
You should consider this relay if you need to monitor energy usage for two separate circuits from a single device. It is ideal for homeowners or small business owners who want to track consumption for lighting or office equipment. The dual power meters provide detailed data for each channel. You will benefit from the ability to control appliances via voice assistants or the app. The compact size fits easily into standard electrical panels. This solution reduces wiring complexity while offering precise energy insights.
Who should skip it
Skip this device if you need more than two channels in one unit. It is not suitable for controlling high-power appliances that exceed 16A continuous load. You should look elsewhere if you require Zigbee or Z-Wave connectivity, as this model uses Wi-Fi and Bluetooth only. If you need a device with a built-in display for local status checks, this relay lacks one. It is also not ideal if you prefer a standalone hub-free setup without Wi-Fi reliance.
Verdict: The Shelly Plus 2PM offers practical dual-channel control with precise energy monitoring. It is a solid choice for users needing detailed consumption data for two circuits.
Key specs explained
Connectivity: Wi-Fi, Bluetooth
You get dual wireless options for reliable communication. Wi-Fi connects the device to your home network for remote access via the app. Bluetooth allows for local setup and control when you are near the panel. This combination ensures you can configure the relay easily and maintain a stable connection even if your primary network experiences minor interruptions.
Smart Home Compatibility: Alexa, Google Home
The device integrates directly with major voice assistants. You can control the two channels using simple voice commands through Alexa or Google Home. This allows for hands-free operation of connected appliances or lighting circuits. It fits into existing smart home ecosystems without requiring additional hubs, making it a straightforward addition for users who prefer voice control over manual app interaction.
Channels: 2
This single unit manages two separate electrical circuits independently. You can control two different devices, such as separate light fixtures or appliances, from one compact relay. This reduces the need for multiple devices in your electrical panel. It is ideal for situations where you need to monitor and switch two loads individually while saving space and simplifying your wiring setup.
Power Metering: Integrated
The relay includes built-in sensors to track energy usage for each channel separately. You can monitor real-time consumption and analyze historical data through the app. This helps you identify which appliances use the most power. The data allows you to forecast energy costs and make informed decisions about usage. It provides actionable insights into your home's electricity consumption without needing external meters.
Compact DIN Rail Design Specs
According to the listing, the Shelly Plus 2PM measures 1.65 inches wide, 1.46 inches high, and 0.63 inches deep. It weighs 0.99 ounces. These dimensions define its physical footprint inside your electrical panel. The compact size allows you to fit two channels into a small space. This saves room for other components in crowded junction boxes. The device is described as blue, which helps you identify it among other relays. The listing notes it is a single pack, meaning you receive one unit per purchase. This count matters if you need to control multiple circuits separately. You must buy additional units for each extra pair of channels. The layout is designed for DIN rail mounting. This standard rail system is common in electrical panels. It allows you to snap the device into place without complex tools. The small height and width keep the profile low. This prevents interference with adjacent breakers or switches. The weight is light, which simplifies handling during installation. You do not need heavy-duty supports. The design prioritizes space efficiency. You can install it in tight spaces where larger controllers would not fit. The physical build supports its role as a hidden control layer. It sits behind walls or in panels, out of sight. The compact form factor ensures it does not dominate your electrical infrastructure. This makes it suitable for retrofits in older homes with limited panel space.
Setup and Everyday Use Guide
You set up the Shelly Plus 2PM using the Shelly Smart Control App. The device supports both Wi-Fi and Bluetooth connectivity. You can use Bluetooth for initial local configuration when you are near the electrical panel. Wi-Fi then connects the unit to your home network for remote access. This dual approach simplifies the installation process inside your panel. Once configured, you can control two separate electric circuits or appliances individually. The device allows you to monitor power consumption for each channel separately. You can track energy usage through the app to analyze spending patterns. This data helps you forecast future costs and manage your electricity consumption more effectively. You can also use the manual switch on the device for direct control. The app lets you create personalized scenes to trigger actions across multiple devices. You can integrate the Shelly Plus 2PM with Alexa and Google Home. This compatibility allows you to use voice commands to toggle circuits or check status. The device also functions as a Wi-Fi repeater, which may extend your network coverage. You receive notifications for automated events through the app. The listing notes a three-year device warranty from Shelly. This setup supports both private homes and business automation. You manage settings individually or combine devices for broader home automation goals. The compact size ensures it fits easily into standard electrical panels without taking up much space.
Before You Buy This Relay
You need to check your electrical panel space before installing this device. The Shelly Plus 2PM fits on standard DIN rails, but you must verify you have room for its width and height. You also need to confirm your home network supports both Wi-Fi and Bluetooth. While it works with Alexa and Google Home, you should verify your specific smart home hub supports these protocols for full automation. You will need basic electrical knowledge to wire two separate circuits safely. This device does not replace a thermostat. It controls lights or appliances. You should use it alongside your main climate controls. Regularly check the Shelly app for firmware updates to keep the device secure. You do not need a separate hub. The built-in Wi-Fi handles remote access. You simply connect it to your existing router. This makes setup straightforward for most users. You can monitor energy use per channel. This helps you track consumption accurately. Ensure your circuits do not exceed the 16A rating. Peak loads can reach 18A, but sustained current must stay lower.
Check before you buy
- Verify DIN rail space in your electrical panel
- Confirm Wi-Fi and Bluetooth support in your home
- Check Alexa and Google Home compatibility with your hub
- Ensure circuits stay below 16A sustained current rating
