The challenge

Traditional smart lighting systems often need specialist wiring, expensive processors and ongoing support, keeping true home automation out of reach for most households. Meanwhile, homes lack a simple way to monitor and cut energy use, leaving potential savings and carbon reductions untapped.

Tewke's Tap technology

The solution

 Tewke has developed Tap, a touchscreen device that replaces an existing light switch with no rewiring needed. It controls lighting, heating and audio, monitors home energy use and tracks home health through onboard sensors, making whole-home automation accessible to any household.
