Let me start by saying this smart switch does exactly what it promises - controlling devices based on temperature and humidity. I've been using it with my space heater for about a month now, and the auto mode is genuinely useful when you want to maintain a specific room temperature.

The good stuff first: The app interface is clean and responsive. I love being able to check my home's temperature from work and adjust settings remotely. The humidity monitoring is surprisingly accurate compared to my standalone hygrometer. Installation was plug-and-play simple - just screw it into your wall socket like any normal switch.

Now the frustrations: Like other reviewers mentioned, the Fahrenheit/Celsius bug is REAL. No matter how many times I set it to Fahrenheit in the app, it randomly switches back to Celsius. Also, one of my units keeps disconnecting from WiFi every few days, requiring a manual reset.

For basic smart control at this price point, it's decent if you can tolerate these quirks. But if reliable unit conversion and constant connectivity are must-haves for you, you might want to look at more premium options.
