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!
