The hardware
The RELO IO8: eight relay outputs and eight digital inputs in one module, powered over PoE+ or USB-C, mounted on DIN rail or in the rack.

Our own platform
After enough projects spent reinventing the same relay cabinet, we started building it as a product. Cueva Control is that product.
Why
Every project contains the same piece: something has to close a contact, something has to read an input, and it has to talk to the rest of the installation. We solved that over and over with a cabinet full of loose parts from four different brands.
Cueva Control is that layer, built properly once. We use it in our own projects, so we are the first to notice what doesn't hold up — and everyone else can simply buy it.

A node-based automation engine runs on the module itself. If the network drops, the logic keeps running; you don't need a server to get a door open.

Cueva Horizon shows you a venue's devices from a distance, and firmware updates go over the air. Useful when the installation is a two-hour drive away.

Integration
No closed ecosystem: the module listens to the protocols this industry already uses.
