Coffee machine Philips 5400 Series LatteGo

I read this articl Watched this video I looked at the ESPHome-Philips-Smart-Coffee project

And I decided to repeat your experience and faced the problem of decrypting the data received in ESPHome

How did you decrypt the protocol? How did you get these bytes?

Could you help decipher the protocol for the 5000 series coffee machine?

How did I find out that the 1000/2000/3000/5000 coffee machines use the motherboard number 1.9.30.330.00._v10, and the control panel is different for everyone

So, I measured the coffee machine with an oscilloscope and a multimeter and that's what turned out. Since the 8-core wire has two colors, black and gray, I had to make a color scheme for convenience. I drew an up-to-date diagram for the 5400 series coffee machine. Since the 8-core wire has two colors black and gray, and the black color is +5v, then for convenience I made colored lines and numbered the wiring

Measurements with an oscilloscope

According to the calculation, the speed is 116279 bits / s I used the calculation formula F = 1/T 1) 8,6/1.000.000 = 0,0000086 2) 1/0,0000086=116 279,0697674419 = 116279 bits / s ![image](https://user-images.githubusercontent.com/64090632/236559742-8acfcd90-7c0f-4f03-b7ee-400a55a1da83.png) ![image](https://user-images.githubusercontent.com/64090632/236559709-bda23f2c-5026-4712-b710-ccd7ced7ab70.png)

Now it remains to understand how to properly capture data from the coffee machine. Now I use this option for debugging

Initially, I used this scheme, but the control of the coffee machine does not work, although the switch turned on/off all the time, and the screen on the control panel turned off all the time. I used a BS170 transistor.

I decided that since the coffee machine turns off all the time and there is no control, I will connect the ESP8266 Wemos Mini just to read the data to try to find the right code
