• ShellyShelly Pro 3EM with Anker Solix (error 35) or Marstek Venus: check the connection and understand the "phase_sequence" warningError 35 "wrong meter connection" in the Anker app and a Marstek Venus that gets no readings from the Pro 3EM often have simple causes: unsupported meter model, Wi-Fi (guest network, weak signal in the distribution board), wrong UDP port or measurement direction. The Pro 3EM's "phase_sequence" warning, according to Shelly, means the phases are not connected in the order A–B–C; according to the forum it doesn't matter for metering itself and can be turned off.
