Smart home and wireless technology icon set

A clean black line icon set sits on a white background, arranged in a simple four-part grid. The symbols include a connected house, a wireless light bulb, a circular thermostat reading 21 degrees, and a Wi‑Fi router with signal waves. Strong contrast and generous negative space give the illustration a clear, technical feel that works well for interface design, presentations, and home automation concepts. Each icon uses rounded strokes and minimal detail, keeping the set easy to read at small sizes. The composition feels orderly and modern, with no color distraction beyond the stark black-on-white palette. Together the icons suggest smart home control, connected devices, energy management, and internet connectivity.
