Eltako Impulse Switch Relay Matter over Wi-Fi ESR64PF-IPM (30064021)

Manual light switching often leads to lights left on unnecessarily, wasting energy. The Eltako ESR64PF-IPM solves this by enabling automated control of lighting circuits through Matter over Wi-Fi, allowing remote and scheduled operation from any Matter-compatible smart home system. This DIN rail mounted impulse switch relay replaces traditional mechanical latching relays, offering silent electronic switching with zero-crossing technology to extend lamp life and reduce inrush currents.

Who is it for

This device is ideal for electricians and smart home enthusiasts looking to retrofit existing lighting circuits with modern, app-controlled switching. It suits residential and commercial installations where a single lighting circuit (up to 16A) needs to be controlled via pushbuttons, a smart home hub, or manually. Its compact 1 TE width makes it perfect for distribution boards with limited space.

Main features

• Matter over Wi-Fi connectivity for seamless integration with Apple Home, Google Home, Amazon Alexa, and other Matter ecosystems.
• Universal control voltage 8-230V UC (AC/DC) allows direct connection to various pushbutton circuits without additional power supplies.
• 1 NO contact rated 16A/250V AC, suitable for incandescent, LED, and fluorescent loads (up to 2000W incandescent, 400W LED).
• Zero-crossing switching ensures silent operation and reduces stress on lamps and relay contacts.
• Manual rotary switch on the front for direct on/off/auto control, even without network.
• Memory function retains the last switching state after a power failure.
• Standby loss of only 0.8W for energy-efficient operation.
• DIN rail mounting (1 TE = 18mm width) for quick installation in standard distribution boards.

Tips

For best performance, ensure the device is within Wi-Fi range and use a Matter-compatible hub or border router if you plan to control it remotely. The universal control input accepts both AC and DC voltages from 8 to 230V, so you can connect existing pushbuttons directly. When switching LED lamps, respect the maximum load of 400W to avoid overheating. Use the manual rotary switch to test the circuit before commissioning the smart features.
