Ruth's sister International Power Cord Kaifa MA105 MA304

SKU CH-4566-ECKTT

Connects Kaifa MA105 and MA304 smart meters to a Raspberry Pi via USB for Domoticz data logging

  • Connects Kaifa smart meters to Raspberry Pi for Domoticz integration
  • FTDI USB-TTL serial interface enables reliable data communication
  • 6P6C connector fits MA105A, MA105C and MA304 meter ports
  • Ready for Dutch P1 Slimmer meter reading projects

Compatible Smart Meter Models

This cable connects Kaifa MA105A, MA105C and MA304 smart meters to a Raspberry Pi. It uses an FTDI chipset to provide a USB TTL UART serial link for Domoticz home-automation integration. The 6P6C plug fits the meter's P1 port directly.

Sustained Data Reliability

The FTDI controller maintains stable serial communication during continuous meter polling. It handles long-term logging without the dropouts common in cheaper bridge chips. Builders needing wireless connectivity or multiple simultaneous meter inputs will require additional hardware.

Questions about this item

Does the FTDI USB-TTL serial interface draw noticeable power when the cable runs continuously?

The FTDI chip draws only a few milliamps from the USB port, so heat and power impact are negligible during all-day use.

Which Raspberry Pi models already have the GPIO header required for this P1 cable?

Any Raspberry Pi with a standard 40-pin GPIO header — Pi 2, 3, 4 and Zero variants — provides the pins the cable needs.
