Thanks guys. I have had some success with the Jura X9 Impressa.
There is a connector on the steam generator relay board beside the DB9 connector.
For the life of me, I could not make heads or tails of the read eeprom responses - they do not seem to reflect the brew counter counts shown on the display. Also the tray water/status is inconsistent and not representative of the machine.

The important part is that I can brew products and turn the machine on and off.
I used a NodeMCU clone without level shifters, getting the power from the same header (5v) to vin pin, and knock on wood - it’s chooching away with the 5v Rx and 3v Tx.

I created alexa voice routines to properly stack the multi-brews required and used the scheduler component to turn the machine on and off on work-mornings automatically.

Thanks guys. I have had some success with the Jura X9 Impressa.
There is a connector on the steam generator relay board beside the DB9 connector.
For the life of me, I could not make heads or tails of the read eeprom responses - they do not seem to reflect the brew counter counts shown on the display. Also the tray water/status is inconsistent and not representative of the machine. The commands do come back starting with a lower-case of what I sent… so it’s not a serial line readback issue as far as I can tell.

The important part is that I can brew products and turn the machine on and off.
I used a NodeMCU clone without level shifters, getting the power from the same header (5v) to vin pin, and knock on wood - it’s chooching away with the 5v Rx and 3v Tx.

I created alexa voice routines to properly stack the multi-brews required and used the scheduler component to turn the machine on and off on work-mornings automatically.

Hiya. I have managed to flash ESPHome on the official wifi dongle, but im not sure whats next. I looked at the github repo which you posted and it seems its for custom made ESP32 connected to the service port, not the official module? Im not sure what config i should put in ESPHome to flash it onto the original wifi dongle, besides that status_led and uart you have posted above.
Particularly, what should i do with .py and .h files?

Hey, I’ve had a Jura impressa F7 (F-series) for years and have been running a variant of the RyanAlden github code on it for years. I run it on a Wemos D1 as the post starts.

But in the past few weeks I’ve made a lot of improvements to it. I can now read a lot more sensors (almost all counter positions!) namely:

  • Single espresso
  • Double espresso
  • Single coffee
  • Double coffee
  • Single cappuccino (*)
  • Single ristretto (*)
  • Double ristretto (*)
  • Movements of the brewing unit (*)
  • Cleanings performed
  • Descaling performed (*)
  • Number of coffee grounds in the drawer (*)

(*) all these sensors are new compared to the original esphome interaction from Ryan Alden

I also optimized it more for the small SRAM memory that a Wemos D1 (8266 chip) has. I’m going to continue with it myself. i still miss the counters for:

  • hot water
  • steam usage

i also want to port it to an ESP32 chip so you can use more SRAM and have a separate dedicated UART port.

It’s still a work in progress, so if you have any improvements, feel free to post a pull request or “issue” on github!

P.S. the release is a stable version but does not contain all the latest found sensors and SRAM optimizations. and for the ESP32 variant a new branch has been created.
