Sonoff S55 with ESPHome?

I ordered an Sonoff S55 to use for switching outdoors.


Recently i flashed a Sonoff S20 with ESPHome, but that was based on a guide from the ESPHome website. So i’m quite new to using ESPHome. But from what i understand from the site is that most Sonoffs will work. So could i use the same code (without the led control part) like this for the S55:

esphome:
  name: <NAME_OF_NODE>
  platform: ESP8266
  board: esp01_1m

wifi:
  ssid: <YOUR_SSID>
  password: <YOUR_PASSWORD>

api:

logger:

ota:

binary_sensor:
  - platform: gpio
    pin:
      number: GPIO0
      mode: INPUT_PULLUP
      inverted: True
    name: "Sonoff S20 Button"
  - platform: status
    name: "Sonoff S20 Status"


switch:
  - platform: gpio
    name: "Sonoff S20 Relay"
    pin: GPIO12

I found here that this works with a template in tasmota. But i’m hoping to use it with ESPHome as this is where i already have a few devices connected.

I don’t have any of these but reading the tasmota template you have linked
the code you have posted has the correct pins, which is the same as a sonoff basic

I don’t know if there’s a LED on them or not but the tasmota template has one defined on GPIO13 (again the same as a sonoff basic)

Also I have a S20 thats using exactly the same config as a sonoff basic. So your S20 config should work with these S55’s

Ok thanks for your confirmation. I will check if there is a LED on it when i receive it.

I received my S55 and there is a blue led on them. I got everything working fine with this esphome config:

esphome:
  name: sonoffs55
  platform: ESP8266
  board: esp01_1m

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password

api:

ota:

binary_sensor:
  - platform: gpio
    pin:
      number: GPIO0
      mode: INPUT_PULLUP
      inverted: True
    name: "Sonoff S55 Button"
  - platform: status
    name: "Sonoff S55 Status"


switch:
  - platform: gpio
    name: "Sonoff S55 Relay"
    pin: GPIO12

output:
  # Register the blue LED as a dimmable output ....
  - platform: esp8266_pwm
    id: s55_blue_led
    pin:
      number: GPIO13
      inverted: True

light:
  # ... and then make a light out of it.
  - platform: monochromatic
    name: "Sonoff S55 Blue LED"
    output: s55_blue_led

I got this working here too, piece of cake, I found the following template worked best for me:

esphome:
  name: sonoff_s55
  platform: ESP8266
  board: esp01_1m

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password
  ap:
    ssid: "Sonoff S55 Fallback Hotspot"
    password: "12345678"

binary_sensor:
  - platform: gpio
    pin:
      number: GPIO0
      mode: INPUT_PULLUP
      inverted: true
    name: "Sonoff S55 Button"
    on_press:
      - switch.toggle: relay1

switch:
  - platform: gpio
    name: "Sonoff S55 Relay"
    pin: GPIO12
    id: relay1

status_led:
  pin:
    number: GPIO13
    inverted: true

Hey guys! Sorry for the dumb question…

Did you have to flash the socket, any way - by flashing I mean, if the hardware needed any interaction - or you only had to use this code in the configuration?

I’m a bit affraid of these tasmota sockets, because earlier they needed hardware modifications. :confused:

This is a Sonoff device. You can use it with HA without modifying it or you can solder pins onto its board to install an alternative firmware (ESPHome or Tasmota for example)
