Every system in your hands. Wire it once, draw the logic, and let the device run it.

Introduction

Seventy seconds on what it does.

Connectivity

Six network protocols, no translators.

From a single trigger to a chain of conditions, the RELO IO8 speaks what the rest of the room already speaks. Nothing to convert, nothing to sit in between.

TCP

Bi-directional control over the network. Send commands and read state back from any device on the LAN or across a WAN.

UDP

Fire and forget messaging for real-time triggers, where latency matters more than delivery confirmation.

HTTP

A REST API for web services, control systems and custom apps. GET, POST and PUT, with variable injection.

OSC

Open Sound Control, straight to lighting desks, DAWs and control surfaces over the same network.

Art-Net

DMX over Ethernet. Trigger relay outputs from a lighting console or a media server without a gateway.

RTP MIDI

MIDI over the network. Notes and control changes to and from DAWs, consoles and controllers, with no hardware interface in the path.

GPIO

Eight opto-isolated digital inputs. Buttons, sensors and dry contacts start any flow in real time.

Bitfocus Companion HTTP and webhooks OSC Art-Net Q-SYS

Power

Two inputs. Always on.

USB-C 5V is the primary supply, and the PSU with EU, UK and USA heads is in the box. Add a PoE+ switch and both inputs run at once, so the unit stays up if either one drops. No extra wiring for redundancy.

Cueva Desktop

Draw the logic. Deploy it.

Connect triggers to actions on a canvas, on Mac or Windows. Push the flow to the controller and it runs there, with or without the app open and with or without a network.

Flow editor

Fifty nodes, five kinds.

Triggers start a flow, conditions shape it, execution paces it and actions make it happen. Queries read the device back into the logic.

See every node

Five Cueva Desktop nodes, one of each kind: a green GPIO Input trigger with only an Output handle, a red Get GPIO State query returning a value, a blue Relay Control action with only an Input, an orange Time condition forking into True and False, and a purple Delay execution node with an Input and an Output

Getting started

First power-on in under three minutes.

Five walkthroughs, from that first boot to expanding the device over the network. The whole set runs under twenty minutes.

Mounting

Three across a single rack unit.

The RELO IO8 is a third of a rack unit wide. Three sit side by side in 1U on the RM99, so twenty four relays cost you one rack space, or a single unit goes on a wall on the WM33.
