WOW brilliant did it support any printer running marlin 2.0

[GamerClassN7]

Would be possible to use it with Carlity Ender 3 With board 4.2.7 which have exposed 5v gnd rx tx pins ?

Maybe would be nice to have button to auto home printer right or to send costume gcode for example to turn off fans and geating by automation after printer finished the print :)

I am open to co-operation in development if possible :)

P.S. Would be nice to convert this repo to officinal ESP external component standard, so it is more easy accessible to other users :) https://esphome.io/components/external_components.html

My configuration was pretty similar to yours.

#define HOST_ACTION_COMMANDS     
#if ENABLED(HOST_ACTION_COMMANDS)
  #define HOST_PAUSE_M76                // Tell the host to pause in response to M76
  #define HOST_PROMPT_SUPPORT           // Initiate host prompts to get user feedback
  #if BOTH(HOST_PROMPT_SUPPORT, TFT_BTT_UI) || BOTH(HOST_PROMPT_SUPPORT, MOD_BTT_UI)
    #define HOST_STATUS_NOTIFICATIONS   // Send some status messages to the host as notifications
  #endif
  //#define HOST_START_MENU_ITEM          // Add a menu item that tells the host to start
  //#define HOST_SHUTDOWN_MENU_ITEM       // Add a menu item that tells the host to shut down
#endif

Is EMERGENCY_PARSER and/or SERIAL_PORT_2 defined?

Can you send the M118 command in gcode or via terminal and see the output in the ESPHOME logs?

Yes, both EMERGENCY_PARSER and SERIAL_PORT_2 are defined.

"SERIAL_PORT_2 2" (pins 16, 17)

Can you send the M118 command in gcode or via terminal and see the output in the ESPHOME logs?

Sending "M118 E1 P0 TEST" in esphome log I receive an empty message and in the LCD notifications "echo: TEST"

By empty I mean this:

just in the midle.

On the other hand, while the esphome log is running, if I restart tft/marlin, I receive this:

Are you able to make the change to M118.cpp from this post and retest the M118 commands? I ran into this problem before but thought it was something unique to my setup/machine.

[fran6120]

Replacing SERIAL_ECHOLN(p); with SERIAL_ECHO(p); SERIAL_EOL(); It compiles correctly but after flashing it there is no serial communication on any port.

[GamerClassN7]

@mulcmu any news on reading the Time remaining and progress ?

[GamerClassN7]

It seams they are read correctly but esp home sets them as unknown for some reason :/

[GamerClassN7]

i also manage to add soem debug messages to code maybe it can help

[GamerClassN7]

how ever i dont see any messages with time elapsed whitch is parsed in this section pf custom component

[GamerClassN7]

could this bee and issue that new version of marlin are not returning elapsed time correctly ?

[mulcmu]

I migrated my printer to Klipper so don't have a way to test this any longer.

The code sends M27 command to get remaining time.
https://github.com/mulcmu/esphome-marlin-uart/blob/e4e13a94faaf5f44fe52af80595c3a97e9b69c18/esphome-marlin-uart.h#L95

The reply from this command needs to activate the logic to process the current print time: https://github.com/mulcmu/esphome-marlin-uart/blob/e4e13a94faaf5f44fe52af80595c3a97e9b69c18/esphome-marlin-uart.h#L336-L358

So you could try to tweak check on line 338 to match what you printer replies to M27 and line 342 based on how long the prefix is before the hour/min/seconds.

@mulcmu thank you for advice
