No commitment. Tu navegador no soporta videos HTML5. Per-room kit What Freeline is and where it fits best --------------------------------------- Freeline is Voltic's room-control kit for hotels that want to start at room level: sensors, thermostat, automation, and operational data without bus wiring or complex renovation work. It fits especially well in retrofits, phased rollouts, and hotels that need to reduce HVAC waste and gain operational visibility without taking on a slower, more complex wired infrastructure project.

Instead of spending weeks configuring devices, Voltic Freeline kits arrive preconfigured and ready for hotel room installation. ![Ilustración de True plug-and-play.](https://voltic.es/cdn-cgi/image/format=auto,quality=78/https://cdn.voltic.es/media/_draft/voltic-kit-abierto.png) ### Security is not «admin1234». Hotel control is business-critical. Voltic devices use AES128 encryption and the platform runs on a Zero Trust architecture.

Instead of hearing it from guest complaints, your team gets real-time alerts and acts in minutes.

Avoid a large upfront CAPEX investment. Voltic is modular: install one floor now and another next season. As a reference, 100 rooms can be installed in one week. ![Ilustración de Deploy modularly, floor by floor.](https://voltic.es/cdn-cgi/image/format=auto,quality=78/https://cdn.voltic.es/media/_draft/building.png) The biggest cost is doing nothing. ---------------------------------- As long as you keep the same system, you keep paying for empty rooms with AC on, sensors with no useful data, and avoidable incidents. Nothing serious. Until you run the numbers. ### Spend 60% less on installation. Without bus wiring or programming, deployment costs drop significantly versus wired KNX/Modbus, in both new-build and retrofit projects. ### Save up to 30% on consumption Remove the keycard and start saving by turning off HVAC and lights when no one is in the room. ### Data. Data. Data. Can you explain where your energy use comes from? If you want better operational decisions, you need data. ![](https://voltic.es/cdn-cgi/image/format=auto,quality=80/https://cdn.voltic.es/media/_draft/voltic-kit-bg.png)### freeline Eliminate the keycard, install without friction, and start reading data. from 450€ per room [ I want to become a partner ](/en/contact) - Detects when no one is present and turns off lighting and AC - Detects open windows and cuts off the AC - Monitors entries, exits, and presence - Enables bulk control—no need to go one by one. - Pre-programmed and ready to install with no construction work - Modular system you can install floor by floor.
