The result is a truly adaptive, sustainable, and scalable smart-lighting solution that transforms warehouse operations.
Results
The joint Yodiwo–IOSEA installation demonstrated substantial operational and energy benefits in real warehouse environments:
-
Over 80% reduction in lighting energy consumption: by illuminating only occupied aisles and dimming inactive areas, energy use dropped dramatically, far exceeding typical LED-only savings.
-
ROI in under 4 years: based solely on energy savings, the payback period is 3 years with further reductions in maintenance costs due to fewer ON/OFF cycles.
-
52,000€ yearly savings: based on 1,283 luminaires, 113 W consumption, and 0.15 €/kWh electricity cost.
-
Millisecond-level responsiveness: ensures seamless transitions even for fast forklifts, maintaining perfect visual comfort and safety.
-
Precision at scale: centimeter-level tracking accuracy across multiple areas with each aisle independently managed.
-
Long-term benefits
-
Extended luminaire lifespan
-
Reduced maintenance needs
-
Data infrastructure enabling future RTLS-based services
-
Enhanced safety and security
Solution
Yodiwo built an intelligent lighting-automation system powered by IOSea’s SEAgnal RTLS technology, enabling accurate, millisecond-level detection of people and forklifts across the warehouse.
How it works:
-
IOSEA Locators (PoE): installed along warehouse aisles, providing continuous real-time tracking.
-
BLE Tags: carried by authorized personnel and mounted on forklifts.
-
RTLS Server + Yodiwo Application Server:
-
IOSEA's RTLS engine computes real-time (x,y) positions with centimeter-level precision.
-
Yodiwo’s lighting-control logic dynamically adjusts the intensity of each DALI luminaire.
-
-
DALI-2 Controllers: increase light where motion is detected and dim or switch off lights where noone is present.
Instant, dynamic lighting response
-
Lights turn on immediately as a forklift approaches.
-
Lights dim or turn off as soon as a zone becomes empty.
-
No noticeable delay or flicker for drivers and personnel.
A future-ready installation:
The same IOSEA-based RTLS network can be reused for:
-
Safety & security monitoring
-
Asset tracking
-
Forklift utilization metrics
-
Worker-presence detection
-
Automatic incident alerts
Challenge
Large warehouse environments present several operational constraints:
-
High energy consumption: dozens or hundreds of LED luminaires remain ON even when aisles are unoccupied.
-
Fast-moving vehicles: forklifts moving at 30–40 km/h require immediate illumination—standard PIR sensors cannot react quickly enough.
-
Sparse activity patterns: many warehouse zones are used only 15–20% of the time, creating enormous potential for energy savings.
-
Occupant discomfort: delayed lighting changes can distract forklift drivers or create safety concerns.
-
Safety blind spots: traditional systems cannot detect hazardous situations such as forklifts approaching from hidden areas, worker falls, or prolonged immobility events.
-
Security & access control: warehouses often contain restricted areas where only authorized personnel should enter but traditional lighting and sensing systems cannot verify access rights or detect unauthorized presence.
-
Scalability: A complete solution must support thousands of square meters, multiple aisles, and decentralized lighting groups.
Yodiwo required a highly accurate, low-latency RTLS backbone that could drive autonomous lighting decisions for every DALI luminaire.
Background
Warehouse facilities, especially high-bay logistics centers, consume significant energy on lighting alone. While LED luminaires improve efficiency, they often remain fully illuminated regardless of actual activity. Traditional motion sensors are inadequate for such environments: they have limited range, slow response times, and cannot reliably detect fast-moving forklifts or personnel across long aisles.
To overcome these limitations, Yodiwo sought a precise, real-time, location-aware lighting-control system capable of adapting instantly to human and vehicle movement.
