FTDI USB TTL Cable for Smart Meters

This FTDI USB TTL cable connects Kaifa MA105 and MA304 smart meters to a Raspberry Pi or similar host through the P1 port. The six-foot 6P6C RJ12 lead carries UART serial data for Domoticz and other home-automation platforms. It is built for users who need a direct serial link between their meter and a Linux-based controller.

Check Meter Model and Host Port Before Buying

Verify that your smart meter is a Kaifa MA105 or MA304 with an active P1 port using the 6P6C RJ12 pinout. Confirm the host device provides a standard USB-A socket and runs software capable of reading UART serial streams at the meter's baud rate. This cable will not work with meters that use a different connector, protocol or proprietary interface.
