I was interested to see you post here that you were having an issue where your machine was turning off after 20-22 minutes, regardless of the standby time you set.
I’m having the same issue with the TillFleisch component with my EP3246. I posted more detail on that issue (and others that may be related) here.
It seems like you’re suggesting here that setting dummy_receiver: false addresses this issue? But that’s surprising, since I don’t have it set and the default value is false already. I’d love to hear any thoughts you have on whether I can stop the machine from going into standby too early.
Hello
Great advice. I was having the same problem. One doubt, is the relay supposed to send a ground signal or 5V signal? I’m a little confused with the different diagrams version available in the documents. Actually I’m using 5V signal and it works well.
I’m interested to give this a try on my 5400. I believe I have all the parts needed but I’m unsure if it’s still possible to compile on an ESP32 using the latest versions of ESPHome device builder. Has anybody updated the code for 2025.8.0?
This code has not been updated. It is better to install ESP Home version 2023.5.0. How to install the ESPHome addon version 2023.5.0, read here.
This project does not guarantee a completely successful conversion of the coffee machine into a smart one. There may be problems such as the failure of the motherboard due to a connection error. The control board with the touch buttons and the screen may also be damaged. If you do not have soldering skills or are not confident in your abilities, it is better to leave the coffee machine in its current condition and use it as it is. This code is unstable. The coffee machine may freeze, not turn on the first time, or turn off at any time. You’ll have to manage on your own. I can’t help you. I sold this model a long time ago and switched to Jura E8.
Decided to use the old version as suggested first. I’m so close. I too damaged the r110 resistor track but I’m able to turn on and off using the relay so not the end of the world.
Machine is all back together but the build coffee functionality does not appear to be working. Also, entities are displaying but interestingly they’re not updating in real time. For example if I retrieve the drip tray it continues to report as in place until I restart the coffee machine, and then it updates to the correct value.
Any ideas what I may have done wrong? I had thought maybe there is an issue with the wiring for the info communication with the mainboard but I can control coffee making using the buttons on the display no problem.

If the control of the coffee machine from the control panel is correct and normal, it means that everything was done correctly. The ESP32 doesn’t have enough memory to process all the data on the fly, you need more memory and, of course, rewrite and optimize the code.
Amazing! Seems to be working now after disabling logging and captive portal. I just need to dig into the functioning of the servo now and work on recipes.
Thanks for your help. Do you have anywhere for coffee fund donations I can contribute to?
I shouldn’t donate. Thank you. If you use the ESPHome web interface to control the coffee machine, I recommend turning off the web server to save memory, just comment on these lines. I also recommend buying several servos, because they often break down, it happens that they turn slowly or stop working altogether.
Happy 2026 to everyone…
I have just stumbled over this thread and would be a big fan of getting my EP5441 smart
So yould anyone just summarize whats the actual status and if there is any possible way to get this working without soldering (and possibly bricking) the machine?
Thank you
Thomas
You can’t do without soldering here. The code has not been updated and does not match the new EspHome libraries. This project is unstable, the coffee machine may turn off at any time, it may freeze. You also risk damaging the motherboard. I personally do not recommend modifying a coffee machine unless you have experience and are prepared to risk losing the machine. If you want to specifically buy a coffee machine for this project, then put this idea out of your head. It is better to take a Jura or Delongi coffee machine with built-in Wi-Fi or Bluetooth, and they have ready-made integration, where soldering is not required, but it is enough to install integration into the Home Assistant, and you can remotely control it.
