Components

Component is anything wired to the ESP8266/ESP8285 chip to be controlled by or send data to it.

Components can be: buttons, switches, relays, LEDs, sensors, displays, MCU units, etc. Every component is assigned in the device template to the GPIO it is wired (connected) to.

Every Tasmota device has some components configured by default. Most often there is a relay, a button and a LED configured as is the case for a Sonoff Basic in the following image.

Bug

Tasmota 9.1 completely redesigned GPIO mapping to allow for future expansion. Read more about the GPIO Conversion

Assigning Components~

If you wish to expand a device with a peripheral component, after properly wiring everything, you need to assign it to a free GPIO in Configure Module page or use command GPIO<x>.

Read more about peripherals.

Tip

GPIOs configured as User (1) are the GPIOs that can be assigned to components in the Configure Module page.
