Software install of Espurna on Sonoff Mini

ESP8266, Hardware, How to, ,

UPDATE starting from firmware 3.5.0 it’s totally different, see http://developers.sonoff.tech/sonoff-diy-mode-api-protocol.html

It’s possible to flash Espurna on the Sonoff Mini using Diy mode via software.

What you need

  • A Sonoff Mini
  • A mobile device capable of creating an Access Point and which can install eWelink app
  • A PC:
    • with Wi-Fi
    • running GNU/Linux (I used Ubuntu 19.10)
    • with a running web server
    • with git installed

Procedure

Here’s the steps I took to do it:

  1. Download and compile Espurna

    $ mkdir ~/project
$ cd ~/project
$ git clone https://github.com/xoseperez/espurna
$ cd espurna/code
$ pio run -e itead-sonoff-mini

  2. Install and configure eWelink app

  3. Update Sonoff Mini firmware (currently the latest version is 3.3.0, I’ve read you need 3.1.0 at least)

  4. Shutdown the device (detach it from mains current)

  5. Enable OTA OTA port
  6. Create an Access Point with your phone. These must be the parameters:
    • SSID: snonffDiy
    • pre shared key (password): 20170618sn
    • band: 2.4 GHz
  7. Boot the device (attach it to mains current)
  8. Wait until it connects to the AP (the blue led double pulses)
  9. Connect the PC to the same Wi-Fi

  10. Search for the Sonoff Mini device on the Wi-Fi network

    $ avahi-browse -t -r _ewelink._tcp
+ wlp1s0 IPv4 eWeLink_10009b8ed6                            _ewelink._tcp        local
= wlp1s0 IPv4 eWeLink_10009b8ed6                            _ewelink._tcp        local
   hostname = [eWeLink_10009b8ed6.local]
   address = [192.168.43.200]
   port = [8081]
   txt = ["data1={"switch":"off","startup":"off","pulse":"off","pulseWidth":500,"rssi":-29}" "seq=1" "apivers=1" "type=diy_plug" "id=10009b8ed6" "txtvers=1"]

    Keep track of the deviceid which is, in my case, 1009b8ed6.

  11. Test if everything works as expected

    $ curl -XPOST --data '{ "deviceid": "10009b8ed6", "data": {} }' http://192.168.43.200:8081/zeroconf/info; echo
{"seq":2,"error":0,"data":"{\"switch\":\"off\",\"startup\":\"off\",\"pulse\":\"off\",\"pulseWidth\":500,\"ssid\":\"sonoffDiy\",\"otaUnlock\":false}"}

  12. Unlock OTA updates

    $ curl -XPOST --data '{ "deviceid": "10009b8ed6", "data": {} }' http://192.168.43.200:8081/zeroconf/ota_unlock; echo
{"seq":2,"error":0}

  13. Put file in a web server

    $ cd ~/public_html
$ cp ~/project/espurna/code/.pio/build/itead-sonoff-mini/firmware.bin .
$ chmod a+r firmware.bin

  14. Test url

    $ curl -s http://192.168.43.53/~max/firmware.bin --output - | sha256sum
e9e7d72d2c2a8b25678cab7ded20645c5e37c60459cbe6ba1448ed3a62f72b72
$ sha256sum ~/public_html/max/firmware.bin
e9e7d72d2c2a8b25678cab7ded20645c5e37c60459cbe6ba1448ed3a62f72b72  firmware.bin

    You will need the sha256sum value in a minute.

  15. Do the OTA, keep attention to use the right deviceid, sha256sum and ip values

    $ curl -XPOST --data '{ "deviceid": "10009b8ed6", "data": { "downloadUrl": "http://192.168.43.53/~max/firmware.bin", "sha256sum": "e9e7d72d2c2a8b25678cab7ded20645c5e37c60459cbe6ba1448ed3a62f72b72" } }' http://192.168.43.200:8081/zeroconf/ota_flash; echo
{"seq":3,"error":0}

Done.
