You can flash it using e.g. esptool: ```bash esptool write_flash 0x00000 firmware/nodemcu-release-13-modules-2022-04-17-19-03-07-integer.bin ``` After flashing, the firmware will need a few seconds to initialize the filesystem. You can use that time to create `config.lua` (see below) and then flash the Python code, e.g. using nodemcu-uploader: ```bash ext/nodemcu-uploader/nodemcu-uploader.py upload *.lua ``` Afterwards, you can check whether everything works using the serial connection, e.g. ```bash pyserial-miniterm --dtr 0 --rts 0 /dev/ttyUSB0 115200 ``` You may need to adjust the `/dev/tty` device name. ## Configuration WiFi, Home Assistant, and InfluxDB configuration is read from `src/config.lua`.
