Shelly Plus i4 is a 4-input scene controller built for helm panels and switch positions on board. It reads switches or push-buttons and triggers scenes or synchronized actions over Wi-Fi, with no relays inside. Running on 5–24 V DC, it matches typical 12/24 V boat electrics and connects to any onboard Wi-Fi network without a vendor hub, so Schooner OS or the Shelly app can read it directly.
- 4 digital inputs for switches, push-buttons, or helm controls.
- Powered by 5–24 V DC, suited to 12 V or 24 V boat systems.
- Multi-click support for up to 12 possible actions per input.
- Fits standard electrical boxes and switch panels for a clean helm installation.
