Getting token from Samsung Ecobubble washer

Connect to wifi

First connect your washer to wifi by using the Samsung Smarthings. I couldn't get mine to work in there because it failed after connecting. It was however connected to the wifi

Get samsung client certificate

This can be retrieved by decompiling the samsung android. However someone else has already done the hard work and you can find ac14k_m.pem at

https://github.com/cicciovo/homebridge-samsung-airconditioner

or

Start listening at port 8889

To retrieve a token we need to request one from the washer trough port 8888. It will return a token to port 8889. We need the client ssl

use server.py to start a listening server on port 8889 and leave this terminal open

python3 server.py

Request a new device token

1. Turn on washer and make sure it is connected to the wifi
2. In another terminal send a token request

   curl -k -H "Content-Type: application/json" -H "DeviceToken: xxxxxxxxxxx" --cert ac14k_m.pem --insecure -X POST https://192.168.XXX.XXX:8888/devicetoken/request 
   

3. Press smart control button on washer

You should now receive a token back in your terminal. If this doesn't work try turning the washer off and on in between step 2 and 3

Test the token

curl -k -H "Content-Type: application/json" -H "Authorization: Bearer <YOUR NEW TOKEN>" --cert ac14k_m.pem --insecure -X GET https://192.168.xxx.xxx:8888/devices/0

Hassio

In home assistant I use the following configuration to be able to get a notification when the washer is done.

- platform: command_line
  command: 'curl -m 8 -k -H "Content-Type: application/json" -H "Authorization: Bearer <YOUR NEW TOKEN>" --cert /config/ac14k_m.pem --insecure -X GET https://192.168.XXX.XXX:8888/devices/0/operation'
  name: "Samsung washer"
  value_template: '{{ value_json.Operation.state }}'
