Using With Sonoff Basic
=======================
.. seo::
:description: Instructions for putting Sonoff basic devices into flash mode and installing ESPHome on them.
:image: sonoff_basic.jpg
ESPHome can be used with Sonoff Basic. These devices are basically just
an ESP8266 chip with a relay to control the connection, a small button on the
front and a green LED light.

Sonoff Basic
This guide will not guide you through setting up your Sonoff Basic step-by-step. It just provide
a sample configuration. For detailed instructions, see :doc:`sonoff_s20`, as those devices are
pretty similar.
.. note::
If you've previously installed Sonoff-Tasmota or ESPurna on your Sonoff Basic, you're in luck 😀
ESPHome can generate a firmware binary which you can then upload via the
web interface.
Sample configuration
--------------------
The Sonoff Basic is based on the ``ESP8266`` platform and is a subtype of the ``esp01_1m`` board.
With this information, you can also step through the ESPHome wizard (``esphome sonoff_basic.yaml wizard``)
if you don't want to use the sample configuration file from below.
Below you will find a table of all usable GPIO pins of the Sonoff Basic and a configuration file that
exposes all of the basic functions.
================================================== ==================================================
``GPIO0`` Button (inverted)
-------------------------------------------------- --------------------------------------------------
``GPIO1`` ``TX`` pin (C1 Pin 2)
-------------------------------------------------- --------------------------------------------------
``GPIO3`` ``RX`` pin (C1 Pin 3)
-------------------------------------------------- --------------------------------------------------
``GPIO12`` Relay
-------------------------------------------------- --------------------------------------------------
``GPIO13`` Green LED (inverted)
-------------------------------------------------- --------------------------------------------------
``GPIO14`` Optional Sensor (C1 Pin 5)
================================================== ==================================================
.. code-block:: yaml
esphome:
name: <NAME_OF_NODE>
esp8266:
board: esp8285

ssid: !secret wifi_ssid

switch:
- platform: gpio

Now run ``esphome sonoff_basic.yaml compile`` to validate the configuration and
pre-compile the firmware.
.. note::
After this step, you will be able to find the compiled binary under
``<NAME_OF_NODE>/.pioenvs/<NAME_OF_NODE>/firmware.bin``. If you're having trouble with
uploading, you can also try uploading this file directly with other tools.
Or run the upload command if your device is connected to the serial interface:
.. code-block:: bash
esphome sonoff_basic.yaml run
More detailed breakdown
-----------------------
1. Programming
**************
Ensure you have soldered on the additional header pins to the PCB and connect your USB FTDI programmer.
See https://randomnerdtutorials.com/how-to-flash-a-custom-firmware-to-sonoff/ for more details on the pinout and FTDI.
1.1. Put Sonoff into programming mode.
**************************************
* Press and hold the toggle pin (long black pin next to LED and custom soldered pins).
* Supply USB power to Sonoff via FTDI (e.g. plug in USB to the FTDI, or use a power switch as explained in link above).
* Keep holding the toggle pin for approx 3-5 seconds now you should be ready to program.
If you get a message unable to communicate when trying flash, check your TX/RX pin or retry entering boot mode again.
Quick notes:
* 3.3V setting on FTDI, 5V will cause damage.
* Ensure the connections on the PCB starts at the closed to the toggle pin, it uses 4 pins, but 5 pins are soldered on.
* TX and RX should be swapped - RX on Sonoff goes to TX on FTDI.
1.2. Upload the firmware
************************
Run this command from the same directory where your <my-awesome>.yaml file is located
.. code-block:: bash
esphome <my-awesome>.yaml run
Or if you're using the dashboard, just click the "UPLOAD" button.
You should get an output starting like this
.. code-block:: text

1.3. And then nothing will happen
*********************************
Once you have flashed the device, nothing will happen. You need to power cycle the device.
You will notice the LED will start to flash and then becomes solid once connected to the WiFi network.
You can follow the logs produced by the running module by running the command
.. code-block:: bash
esphome <my-awesome>.yaml logs
Your output will possibly look like this

1.4. Test now with OTA flashing
*******************************
Before installing the Sonoff, do a final OTA test, and this time selecting the OTA option and NOT the USB option when reflashing.
.. code-block:: bash
esphome <my-awesome>.yaml run
Once these actions succeeded you are pretty much in the clear and can be sure your device is ready.
