EP3241 Issues

[joelguth]

Hey there!

First off awesome work on this project!

I just finished my PCB assembly and am testing in an EP3241. One thing I've noticed is that if I turn off the machine with the "switch" from esphome or from the display, it shuts the machine down and runs a clean cycle when it turns off. If I just let the machine sit idle, it seems the machine just immediately turns off as if power is cut.

Is there a difference with how the idle timeout is handled in the program loop vs that of turning the machine off?

Also, is there a way to extend the time before this idle shutdown happens? It seems to happen fairly quickly if no buttons are pressed on the machine.

EDIT: nevermind, now I'm very confused. Maybe the EP3241 isn't working as seamlessly as I had initially thought. Many of the buttons work, but there is some odd behavior like the machine seemingly just turns off even if I am pressing buttons.

Let me know if there's anything I can do to provide additional debugging.

Thank you!

Here's some debug logs. It just randomly immediately shuts down when i'm selecting different beverages and sizes from the esphome device:

Is there a difference with how the idle timeout is handled in the program loop vs that of turning the machine off?

The software switch does the exact same as pressing the button on the display. If some type of coffe has been prepared, the machine will perform a cleaning cycle during shutdown. The ESPHome switch does not turn the machine off automatically, unless explicitly specified through some automation/config. Note, that the coffee machines have an internal timeout for shutting down, which can be changed IIRC (see manual).

Does the same behaviour appear if you remove the power switch from you configuration?

Also make sure you don't have any automations running that could interfere with the normal operation of the device.

A log of the Mainboard TX UART would be great , maybe this contains some useful information. The provided log looks 'normal' at first glance.

The EP3241 could also be misinterpreting the commands for all I know... Depends on the machines implementation. Is this behaviour reproducible with a specific type of beverage?

There is already an open discussion regarding the EP3241: see #55 We should move this discussion there if this isn't an issue with the existing implementation. You could also try to use the commands from the related thread to see if they resolve the issue.

Yeah it just seems to be shutting itself down pretty immediately and in some cases just seems to skip the cleaning cycle even if something was brewed. It's as if it's receiving a command it's not expecting and just powering down?

here's another instance from today:

Happy to move into a proper discussion, I have the debug currently enabled on the mainboard UART using the filter you have described here: https://github.com/TillFleisch/ESPHome-Philips-Smart-Coffee/issues/7#issuecomment-1941624536

Let me know if i should remove that filter to help further debug, or if there's a better way to collect the Mainboard UART logs.

Let us continue any related discussion in #55 until we have working EP3241 support
