Wiring and Setup Guide
Connect the IO-Extender 150 to your GX device's USB port — it's detected automatically in Venus OS v3.60 or later. Use the spring terminals for tool-free wiring of sensors and actuators, then configure I/O behavior and Node-RED automation flows from the SwitchPane dashboard.
Connecting a Tank Level Sensor
Wire the sensor output to one of the 8 configurable digital inputs, assign the input type in Venus OS settings, and the level appears on your Cerbo GX display and VRM portal.
Relay Automation: Generator Start
Use the PWM and solid-state outputs with added relays to auto-start a generator on low battery voltage, switch pumps on schedule, or trigger alarms from any sensor input — all built with Node-RED logic.
