As energy costs rise and efficiency becomes a top priority, homeowners are looking for smarter ways to control their indoor heating. A smart thermostat plug for portable heaters is a simple yet powerful solution that brings automation, safety, and energy savings to your portable heating setup.

🔍 What is a Smart Thermostat Plug?
A smart thermostat plug is a Wi-Fi-enabled or programmable plug-in device that sits between your portable heater and the wall outlet. It includes a temperature sensor and a smart controller that automatically turns the heater on or off based on your preferred temperature settings.
Some models also connect to your smartphone via an app, allowing remote control, scheduling, energy monitoring, and even voice command integration through Amazon Alexa, Google Assistant, or Apple HomeKit.
