Tewke: The AI Powered Smart Grid Interface
“Tewke is a climate-technology manufacturer challenging the US-dominated smart home market. Based in the UK, they engineer and assemble the 'Tap'—a hyper-intelligent control interface designed to replace standard light switches. Unlike mass-market imports, Tewke’s hardware is precision-engineered in the UK to bridge the gap between the domestic home and the national smart grid.”
1. The Heritage
Founded by serial entrepreneur Piers Daniell, Tewke was established with a singular mission: to decarbonise the home without compromising on design. While the "smart home" sector is often associated with disposable gadgets and planned obsolescence, Tewke treats home automation as critical infrastructure.
Tewke is a certified B-Corp organisation, representing a new wave of British industrial startups that prioritise ethical manufacturing and grid-level sustainability over quick-turnaround consumer electronics.
2. The Location
Tewke operates from London and the Midlands. All R&D and assembly teams are based in the UK. Crucially, they have committed to a domestic manufacturing model. Despite the pressure to offshore electronics production to Asia, Tewke’s devices are hand-assembled by skilled technicians in the UK. This local oversight ensures that every unit meets strict quality standards before it reaches the wall of a home.
3. The Difference
No-Neutral Retrofit: The engineering breakthrough of the 'Tap' is its ability to work without a neutral wire. This makes it compatible with the vast majority of older UK housing stock, democratising smart tech for period properties that usually require expensive rewiring.
Grid Intelligence: Unlike standard "remote control" switches, Tewke devices monitor real-time energy pricing. They are designed to work with variable tariffs, automatically advising users on the cheapest times to run high-load appliances.
Environmental Monitoring: The hardware is packed with nine distinct sensors, actively monitoring indoor air quality, humidity (critical for preventing damp in UK homes) and CO2 levels.
Privacy-First Architecture: In an era of always-listening speakers, the Tewke AI assistant is engineered to activate only when physically touched, ensuring that data privacy is baked into the hardware design.
4. The Hero Products
The Tap Smart Switch: A high-resolution OLED touchscreen interface that replaces a standard light switch. It acts as the "brain" of the room, controlling lighting scenes, monitoring energy usage, and managing other connected devices via Matter and Thread protocols.
Tap Core (Coming Soon): A capacitive touch version designed for secondary rooms, offering the same build quality and mesh-networking capabilities in a simplified format.
