IoT

Let’s get some ESPHome firmware flashed on to your ESP32 solar-powered IoT project! I’ll show you the basics of building the base firmware to get it attached to your WiFi network, some tips and tricks for working with mDNS across subnets, and leave you with a working OTA-managable solar-powered sensor!

Let’s get your newly-deployed Home-Assistant instance set up, get those day-one add-ons installed, and get some best practices for backups and updates knocked out!

In this video, we built a solar-powered, 18650 battery-backed ESP32-powered sensor, sitting in a compact 3D printed housing. This is using a temperature, humidity and barometric pressure sensor, known as the BME280, which runs on the i2c bus. Additionally, we’re using a TP4056 charge controller, the updated version with low-voltage protection!
