How to update the ESPHome ESP32 / ESP8266 device firmware

Update the ESPHome dashboard or CLI first (`pip install -U esphome`, or pull the new Docker image).
Then re-flash each device over the air from the dashboard.
Devices on much older firmware may need a USB flash if OTA fails.

Always download firmware from the manufacturer or project itself. Firmwarely links out; it never hosts firmware.
