Wi-Fi Single-Phase Energy Meter 16A Type: LEW-01 SPL10000038

Smart energy consumption monitoring in your home

Are you looking for a way to control your electricity consumption and optimize costs? The LEW-01 energy monitor is the perfect solution. The device, operating in the Supla system, allows for precise measurement and analysis of electrical energy parameters in single-phase circuits protected by a 16A circuit breaker. This gives you full control over your power consumption and the ability to identify areas where you can save.

The LEW-01 monitor is not only a tool for end users. Its easy mounting on a DIN rail (TH-35) and two-way measurement make it also indispensable for installers working on photovoltaic installations – it allows monitoring of both energy drawn from the grid and supplied by solar panels.

Functionality and possibilities

The device offers a wide range of functions that translate into real benefits:

• Two-way measurement: Precisely measures both energy drawn from the grid and supplied to it (e.g. from a photovoltaic installation).
• Direct measurement: Does not require the use of additional current transformers, simplifying installation and reducing costs.
• Wi-Fi communication: Enables remote access to measurement data via the Supla mobile application and data export to a CSV file.
• Integration with Smart Home systems: Works with popular platforms such as Home Assistant, Grafana, Zabbix or Power BI, allowing for extensive data analysis and process automation.
• Optical signaling: An LED indicates the device's power status.
• Compact dimensions: A width of one DIN module (17.5 mm) makes it easy to mount in tight distribution boards.
• Voltage aberration: The monitor checks if the voltage is within acceptable limits.

Installation and application

The installation of LEW-01 is simple and intuitive – the device is mounted on a standard TH-35 DIN rail. It is important that the installation is carried out by a qualified electrician with appropriate SEP 1kV qualifications. The monitor finds application in:

• Homes and apartments – control of energy consumption by individual circuits (lighting, sockets).
• Photovoltaic installations – monitoring the energy exchange between the grid and the PV installation.
• Small businesses – optimization of electricity costs.
• Public buildings – monitoring energy consumption to improve energy efficiency.

The device complies with safety standards (IP20) and is designed to operate at temperatures from -10°C to +55°C. Remember to choose wires with a cross-section of up to 2.5 mm² for the power connection.
