Wifiplug

Wifiplug is a smart plug that lets you control any plugged-in device from your phone, set schedules, and use voice commands with Apple HomeKit, Google Assistant, Amazon Alexa, or Cortana. It also tracks real-time energy consumption so you can see exactly how much each appliance costs and adjust usage to save money. The plug is compact — billed as the world's smallest smart plug — and ships from the UK with free delivery and a 60-day return policy.

The Wifiplug app gives you full control: turn things on and off remotely, create timers, or link with your favourite voice assistant. Standout features include real-time energy monitoring with your own kWh rate, compatibility with all major smart home platforms, and an open API for developers. If you're a developer, you can request API keys and use the provided client libraries to integrate Wifiplug into your own projects in minutes. The device has been sold to over 50,000 customers and is one of the few Apple-endorsed smart plugs in the UK.

Wifiplug is best for homeowners who want simple home automation without needing a hub. Common use cases include turning lamps on when you walk in, switching off hair straighteners after leaving the house, or automating a coffee maker to start each morning. Developers and tinkerers will appreciate the open API for building custom integrations. The company is based in Leeds, UK, and has been in the IoT space for over a decade.
