Hotel Technology Systems – R&D, Hardware and Software Development

ETS Elektronik is not merely a manufacturer of automation devices but a technology and engineering centre that develops the entire process in house — from hardware design to embedded software, from central monitoring interfaces to site-specific control algorithms. By analysing the harsh electrical conditions and high inrush currents encountered in the field, we design long-life, stable and highly energy-efficient solutions.

PCB and Hardware Design

Our hardware architecture is engineered to industrial standards for 24/7 uninterrupted operation.

• High current and power endurance: Reinforced PCB current paths and high-quality relay blocks for 30A general power and 16A lighting/climate lines.
• Compact DIN rail standards: Modular case designs optimised from 2 to 10 modules.
• Noise and overvoltage protection: SMPS and transformer integration protected against mains fluctuation, interference and electrostatic discharge.
• Easy on-site maintenance: Fuse structures replaceable without removing the unit, and reliable terminal connections.

Embedded Software and Smart Decision Algorithms

• Multi-parameter occupancy analysis: Algorithms that process presence sensor, door switch and card holder data in one stable logic chain, reducing faulty power cuts to zero.
• Door vibration / noise filtering: A dedicated architecture preventing false triggering on door slams.
• Three operating architectures: Flexible firmware running ONLY SAVER, ONLY PIR and HYBRID modes from a single board.
• Secure RFID verification: Encrypted card recognition protocols that filter out non-standard or unauthorised MIFARE cards.

Central Monitoring and Online Management Software

• Live room monitoring — instant view of guest, staff or vacant room status.
• Request and service tracking — DND, MUR, technical service and emergency calls routed to the right staff.
• Staff performance analysis and remote climate / power management.

Custom Project Development (OEM / ODM)

We provide project-specific engineering: adapting Energy Saver holders and DND panels to other manufacturers’ decorative ranges, VRF/VRV and PMS integration, and retrofit modernisation without disturbing existing infrastructure.
