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=85/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.

HVAC incidents can trigger real-time alerts so the team can act before they become a guest complaint.

Avoid a large upfront CAPEX investment. Voltic is modular: install one floor now and another next season. Timing is agreed by phase based on access and operations. ![Ilustración de Deploy modularly, floor by floor.](https://voltic.es/cdn-cgi/image/format=auto,quality=85/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. ### Compare installation cost per project. Without bus wiring or programming, the scope can differ from wired KNX/Modbus; comparison depends on works, materials, and labour. ### Evaluate consumption savings Remove the keycard and measure the effect of switching off HVAC and lighting when nobody 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 449€ per room [ I want a quote ](/en/sales) - 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.

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.

Notes on the figures -------------------- 1. 1 100 rooms in one week: reference pace recorded in projects at hotels managed with Voltic over the last three years, using preconfigured kits, coordinated access, and no complex building work. Each rollout is scheduled around staffing, integrations, access windows, and building conditions. Note updated 12 August 2026. Hotel BMS comparisons to define your strategy --------------------------------------------- Practical guides comparing Voltic with KNX, wired BMS, keycards, and traditional routes, focused on works, PMS, maintenance, and phased rollout.
