ESPHome - Is the host a special host device (special firmware)?

Hello,
I want to start with ESP home, but I don’t understand how the host will work.

Do I need to flash a special host firmware onto the first ESPHOME device using the ESPHome Device Builder?
And will this device always remain the host and not be used productively?
Will additional devices be added afterward?
What happens if the host dies? Will all other ESP devices then no longer be accessible?

Or is first ESPHome device only necessary to flash firmware onto it using the ESPHome Device Builder, and can the device also be used as a thermometer, for example, with the appropriate firmware?

ESPHome is a firmware for ESP chips and devices.
It adds a basic platform to the device that can be used with “plugins” to add functionality and connectivity to other parts you connect to the chip or device.
The platform also enables a WiFi connection to HA.

ESPHome does not need a hub, which is what you describe in your post.
It can connect directly to HA and both the first the second and you number 100 device will do so.
If one of them dies, then it only affect that device.

Did you find some special host firmware?

They are all treated the same way. Not like your first girl/boy friend…
