Noiseless and wear-free automation for your smart home

Maximize the reliability of your automation setup with this advanced expansion module designed for solid-state relays (SSR). Unlike traditional mechanical relays that click and wear out over time, this solution offers completely silent operation and a virtually limitless lifespan. This makes it ideal for applications requiring frequent and rapid switching, contributing to a more stable and energy-efficient indoor climate.

Precision control for ultimate comfort

The module integrates seamlessly into your existing Shelly ecosystem, allowing you to manage demanding tasks with high accuracy. Its compact design ensures a smooth installation, while the absence of moving parts guarantees maintenance-free performance that aligns perfectly with a modern, technology-driven home layout.

Application Areas

• Precise heating control: Perfect for pulse-width modulation (PWM) of electric underfloor heating or electric radiators to maintain a smooth, comfortable room temperature.
• Noise-sensitive environments: Install in bedrooms, hotel rooms, or living areas where the continuous clicking of mechanical relays would disturb the peace.
• Industrial and heavy-duty automation: Utilize in setups where loads need to toggle on and off thousands of times a day without any risk of mechanical failure.
• Smart pumping systems: Manage circulation pumps and ventilation fans with high precision based on real-time data from your connected sensors.
