Hey guys, for small projects, which protocol do you usually prefer to use? Wi-Fi, Zigbee, or LoRaWAN? Why did you make that choice? For example, is it distance, power consumption, simplicity, or another factor that influences your decision? Would love to hear about your experiences!
Which IoT protocol do you prefer?

For example, if I prefer LoRaWAN, it's basically to escape that annoying battery replacement routine 😅. You can leave a sensor on a building roof for months, and distance isn't really an issue. Sure, the data rate is way lower compared to Wi-Fi, but no one expects 100 Mbps just to send a small temperature reading. As for Zigbee, it offers similar advantages, but it gets complicated because you need to add nodes to the network. With LoRaWAN, there’s no such stress—just mount the transmitter and forget about it!
Wi-Fi, on the other hand, I often see in home automation, especially when using something like a Raspberry Pi as the central system. Zero setup hassle, and you can easily pull all the data via JSON APIs. But yeah, don’t even mention battery life—it has to stay plugged in all the time. Ultimately, it depends on the project’s needs; if constant data transfer is required and network access is easy, Wi-Fi is appealing. If it’s a remote forest sensor, LoRaWAN is the savior.
I usually prefer **Wi-Fi** for my hobby projects, especially when using modules like ESP32 or ESP8266. The reason is simple: wireless networks are everywhere, setup is easy, and it’s ideal for cloud integration. For example, you can instantly transfer sensor data to Google Sheets or an MQTT broker. Of course, power consumption isn’t the most efficient, but you can still run it for weeks on small batteries. The biggest advantage is that it connects to a standard router—no need for an extra gateway, which is really convenient.
If you’re thinking about switching to **Zigbee** or **LoRaWAN**, you’ll need to buy a gateway right away. Zigbee, for instance, is great for home automation (like Philips Hue), but setting up the user interface and ecosystem can be a bit of a hassle. LoRaWAN, on the other hand, has incredible range (up to 10km!), but you’ll have to deal with slow data transfer and annoying FCC/regulatory certifications. Plus, LoRa modules tend to be quite expensive. So, if you want simplicity and speed, Wi-Fi is usually the best choice.
