ESPHome Sonoff DIY BASICR2 configuration error

ESPHome

Please can someone give me a bit of help on how to resolve this problem.

I have a Sonoff basic R2 which have been part of my home Assistent configuration for a couple of years I want to to make a few minor changes to the Yaml configuration (primarely description) but I found that the original YAML file no longer compiles corectly. and I am lost in trying to fix this.

Here is the compile error:

esphome-web-d5b2af (board: esp01_1m; framework: arduino; platform: platformio/[email protected])

ESPHome Sonoff DIY BASICR2 configuration

INFO ESPHome 2025.5.2
INFO Reading configuration /config/esphome/esphome-web-d5b2af.yaml…

INFO Compiling app…
Processing esphome-web-d5b2af (board: esp01_1m; framework: arduino; platform: platformio/[email protected])

MissingPackageManifestError: Could not find one of ‘package.json’ manifest files in the package

I believe that could be that the framework arduno might be the casue but so far I have not been able to find out what it should actually be. Looking through the example in the documention: Sonoff-BASIC-R2-v1.4

Here is the relevant part of the YAML confiuration file:

substitutions:
  device_description: "Ventilator no 2"

esphome:
  name: esphome-web-d5b2af
  comment: "${device_description}"

#esp8266:
#  board: esp8285
  #board: esp01_1m

esp8266:
  board: esp01_1m

# Enable logging
logger:

# Enable Home Assistant API
api:

ota: 
  platform: esphome

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

  ## Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Esphome-Web-D5B2Af"
    password: "9f9PJlQ845EX"

web_server:
  port: 80

I hope someone have a good idea for me or can point me in the direction of the documentation that can resolve this for me.

Have you tried “clean build files”? It’s on the devices ellipsis menu in ESPHome builder.

thank you Daryl,

I have now tried that and had no luck I am still getting exactly the same error message.

I don’t know if it gives any good ideas but here is the log download from the Device. note this was actually compiled in 2022 with the same YAML. I have around 8 devices currently performing correctly but none of them will compile same error as in my original message
