Firmware

Firmware, in this context, is a binary file that is written to a microcontroller unit (MCU) on a PCB. It is the file that has the instructions that a microprocessor follows.

The process of writing the firmware to microcontroller devices is called flashing.

The firmware installed on our devices is developed and maintained using ESPHome.

Of course, there are many kinds of computing device hardware, hence many way to develop, maintain, build, and install firmware
