Hi everyone, I’m trying to build some battery-operated sensors for my Home Assistant setup, and I wanted to share my progress and ask for advice. I’ve got a few different sensors in mind: one with a PIR motion sensor and a DHT11/22 for temperature and humidity, another with a PIR and a DS18B20 for more precise temperature readings, and some magnetic reed switches for doors and windows. I’m thinking of using an Arduino Nano or an ESP8266 for the microcontroller, paired with RF 433MHz modules for communication. I’ve heard great things about ESP8266 for its Wi-Fi capabilities, but I’m not sure if it’s the best fit for battery life. Has anyone had success with similar setups? I’m also considering the best way to handle the RF communication—should I stick with 433MHz or look into something else? Any tips on optimizing battery life would be super helpful! I’m really excited to get this working and would love to hear your thoughts or experiences with similar projects. Thanks in advance for any advice you can share!
