LiteTrace Introduces Bluetooth Wall Switch with Integrated Occupancy Sensor and Dimming

William Attardi on April 8, 2026

The Keilton+autani IWS102/DWS102 by LiteTrace Brands transforms standard wall switches into intelligent control hubs that manage both hardwired lighting and networked devices based on occupancy, without requiring ceiling-mounted sensors or fixture modifications. Unlike typical occupancy sensors that only control their hardwired load, the IWS102/DWS102 offers dual control architecture: hardwired occupancy-based switching for connected lighting plus wireless Bluetooth control of additional networked loads. The integrated 4-button interface provides manual dimming and On/Off control while occupancy functions operate independently. A single wall-mounted sensor orchestrates lighting and equipment control across an entire room through the Keilton+autani Bluetooth network, including plug load controllers (WF20R) for appliances and equipment. Ideal for conference rooms, private offices, lunch rooms, storage areas, copy rooms, and restrooms where coordinated lighting and equipment control maximizes energy savings.

Improving Building Operations with Cloud-Based Applications by Rahul Chillar

William Attardi on April 28, 2025

In today’s rapidly evolving digital landscape, the integration of internet of things (IoT), artificial intelligence (AI), and further smart building technologies is transforming the operational management of real estate. With an increasing need for data-driven decision making, the implementation of building operation systems gains momentum. Since 75% of commercial buildings are not managed as efficiently as they could be, there is huge potential to build on. Cloud-based building operation applications can be viewed as indispensable for future-proof facilities management. As the number of connected devices is expected to exceed 75 billion by 2025, data collection in commercial buildings is becoming more relevant than ever. Now buildings can be operated remotely and conveniently from anywhere. This transformation was possible as technology, such as sensors, have been integrated into building equipment, providing essential data. Strategically deployed throughout the property, sensors are monitoring critical areas such as Heating, Ventilation and Air Conditioning (HVAC), lighting, water management, fire safety, or security. Once the sensors have collected the data, they can display it in a cloud-based building operations application. Improving Operations: Cloud-Based Building Operation Systems

The Statue of Liberty was made with copper but due to oxidation, it turned green.

When the “Lady in the Harbor” first arrived in New York in 1886, she didn’t look like the mint-green icon we know today. In fact, for the first twenty years of her life, she stood as a towering, metallic beacon of reddish-gold. Designed by French sculptor Frédéric Auguste Bartholdi and engineered by Alexandre Gustave Eiffel, the statue was a gift from France to America. To build her, Bartholdi chose copper for three practical reasons:

  • Malleability:It could be hammered into elaborate, thin sheets.
  • Weight:Copper is lighter than stone or bronze, making it easier to ship 350 individual pieces across the Atlantic.
  • Durability:It was strong enough to survive a 27-day ocean voyage and the harsh winds of the harbor.

When she was unveiled on October 28, 1886, her skin—made of 300 copper sheets roughly the thickness of two pennies—shone with a bright, metallic brown luster. The transformation from “penny-colored” to “patina-green” wasn’t planned. Bartholdi actually expected the statue to age into a deeper, darker red. However, the unique environment of New York Harbor—a mix of salt air, moisture, and industrial pollution—triggered a process called oxidation.

The Timeline of Change:

  1. 1886–1900:The bright copper dulled into a dark, muddy brown.
  2. 1903:The first hints of a light green crust, or “patina,” began to appear.
  3. 1906:The color change was so controversial that Congress nearly stepped in. They appropriated $62,000 to paint the statue back to its original color, but the public protested, calling the idea “sacrilege.”
  4. 1910–1920:The statue was a patchy mix of brown and green until 1920, when the oxidation was complete, leaving her entirely teal.

While we now view the green color as iconic, it actually serves a vital structural purpose. The layer of verdigris (the green patina) acts as a protective shield. It seals the copper underneath, preventing the metal from further corrosion and weathering.  By the time the color fully changed, a new generation of immigrants had arrived in America seeing a green statue.
