The Smart Envi SE5012D is a 120-volt hardwired electric panel heater rated at 500 watts, meant to warm a single room from a wall mount. Its 4th-generation design adds a digital thermostat, Wi-Fi with a phone app, and Amazon Alexa and Google Home control, so you can set temperature, group units by room, and turn heat on or off when you leave or come home. It competes with basic wall panel heaters on smart control and styling rather than raw output; 500 watts is modest, so it suits small rooms and spot heating more than whole-home warmth. Owners rate it well overall, though the hardwired install and app setup are the usual friction points.

Owners rate it about 4.3 out of 5 across a small set of ratings. They like the slim wall profile and the app and voice control, and most complaints center on installation and app setup rather than heating performance.
The Smart Envi SE5012D is a wall-mounted, hardwired 120-volt electric panel heater rated at 500 watts. It is a fanless, 100% convection heater that warms a room of 130 to 150 sq ft. It has an onboard digital thermostat and can also be controlled from the Smart Envi smartphone app.
Dual-stack convection uses the "stack effect" to draw cool air in from the floor and release heat out of the top. This creates a slow movement of warm air around the room. Because there is no fan, the heater does not blow dust or allergens around. The heater is slim, at just 2 inches thick.
The app works over Wi-Fi with no hub required. It offers timers, scheduling, geofencing and smart zones that group heaters by room. It works with Amazon Alexa and Google Home, and control can be shared with invited users. Safety features include a child lock, Wall-Sens technology that cuts power if the heater is removed from the wall, and automatic thermal cutoff.
