Dimmer & switch eQ-3 AG HmIP-PDT External White

The eQ-3 AG HmIP-PDT External White is a compact external dimmer and switch designed for integration into HomeMatic smart home systems. It accepts an AC input voltage of 230 V at 50 Hz and communicates via RF at 868 MHz. With an IP20 rating and small dimensions of 70 mm x 39 mm x 70 mm, this white device is intended for indoor installation where reliable remote control of lighting and switching functions is required.

Advantages
