Smart Door Sensor
Andrew Y.

as a software dev, i'm always skeptical about these budget-friendly smart home devices, but this one surprised me. i bought it hoping for a simple way to monitor my front door without breaking the bank, and it's delivered fairly well. the courier called ahead for delivery, which was a nice touch. in reality, it does exactly what it says: pings me when the door opens, and i can check in from anywhere. it's not perfect—the dependency on wifi is a bit of a weak spot—but for the price, it's a solid addition to my home setup. i'd recommend it to anyone looking for a basic, reliable sensor without the fancy extras.
- Pros: i was expecting a hassle, but setting this thing up was a breeze—no tools needed, just stuck it on the door and it started working. the alerts come through instantly on my phone, which is great for keeping tabs on things when i'm not home. it integrates smoothly with my other smart home gadgets, so i can control it with voice commands or set up automations without any fuss.
- Cons: from what i feel, it relies heavily on a stable internet connection, so if my wifi acts up, it's pretty much useless. also, the app could be a bit more intuitive; it took me a minute to figure out some settings, but it's not a deal-breaker.
