La Marzocco GS/3 & Linea Mini support

pixsoul · January 3, 2022, 8:54pm

Hi All,

This is probably more a templating question than a LM specific issue, but I thought others might also like a similar notification when coffee machine is at temperature you’ve specified.

Thus far not working until my 10 minute timeout; I trigger an automation when the machine turns on and I’m trying to use a wait trigger to wait until boiler temp is >= target temp…any ideas getting the below working? Or any better solutions to the problem?

I think the issue is how I’m trying to get the state attribute and compare it’s value as greater than or equal to another attribute. All the state_attr examples I can find are more like a boolean is a value, like

is_state_attr(‘water_heater.linea_mini_coffee’, ‘93’)

Current automation yaml:

- id: '1636944805816'
  alias: Coffee Machine at Temp
  description: ''
  trigger:
  - platform: state
    entity_id: switch.linea_mini_main
    to: 'on'
  condition: []
  action:
  - wait_for_trigger:
    - platform: template
      value_template: '{{ is_state_attr(''water_heater.linea_mini_coffee >= water_heater.linea_mini_coffee.temperature'')
        }}'
    timeout: 00:10:00
  - service: notify.mobile_app_ken_s_pixel_5
    data:
      title: Espresso Ready
      message: Boiler has reached 93
  - service: tts.google_translate_say
    data:
      entity_id: media_player.kitchen_display
      message: Espresso Ready
  mode: parallel
  max: 10

There are several problems there. I recommend spending a bit of time reading this. This is more like what you want:

  - wait_for_trigger:
    - platform: template
      value_template: '{{ states("water_heater.linea_mini_coffee")|float >= state_attr("water_heater.linea_mini_coffee", "temperature")|float }}'
    timeout: "00:10:00"

Thanks @rccoleman - Was able to get it to work with that and thanks for link to that doc. Have learned a few things about templating that I didn’t understand prior.

@rccoleman great work!

Whenever the pump is running, either for espresso or flushing, I get a constant stream of these:

Z (whoa)

I’m interested in this stream to build my own shot timer. I checked your lmdirect repo but couldn’t find out, how to get it (I can get communication running, get status and so on, but I’m no pro in this low level communcation). Is there a way to detect, whether the pump is running with your provided code?

rccoleman · January 24, 2022, 11:15pm

The library currently only stays connected to do periodic polling and receive the responses, so it won’t reliably receive these unsolicited messages. It would need to stay connected all the time to see the whole Z sequence, and without that I don’t know how you’d get real time feedback and the pump starting and stopping.

Hi, when I try to configure the La Marzocco Expresso integration I get a “Unknown Error” message. I use the Client ID 4_2d2impykbv0g44oc88kogw000s8wgwwgws80ccowkcg0wk8o8w and Client Secret 1m52x65srmysk4owk0ww4ok84sw484ww0gsoo0kc0gs4gcwkko, plus my Username and Password. I have the Linea Mini. Running HA on a dedicated Raspberry Pi 4.

rccoleman · January 29, 2022, 7:13pm

What does the HA log say?

LanaiBoy · January 29, 2022, 7:18pm

hmm, I checked the logbook right after attempting to Configure just now, no entries. There are entries for a Fan, but not sure what that is about. BTW, I am very new to HA, HACS, etc. Thanks for the help!

LanaiBoy · January 29, 2022, 7:21pm

rccoleman · January 29, 2022, 7:23pm

The log, not the logbook. Configuration->Settings->Logs

LanaiBoy · January 29, 2022, 7:26pm

Well, now you know the experience level you are dealing with!!

I know about that one, and it won’t cause the failure you’re describing. There should be more there, but I just recommend checking your credentials.

LanaiBoy · January 29, 2022, 7:37pm

Sorry, credentials as in Username and Password in the La Marzocco dialog box, right? Yes, I was careful in typing in my Username and Password for HA. Just to be sure, I logged out of HA and logged back in with my user name and password.

rccoleman · January 29, 2022, 7:49pm

The credentials when configuring the integration. Without additional logs, there’s not much more I can do. Have you used the official app to register your machine? Does that work?

LanaiBoy · January 29, 2022, 7:53pm

Sorry, is this the additional logs info:

Seems clear enough:

LanaiBoy · January 29, 2022, 8:09pm

One last question I hope. How do I delete the La Marzocco integration in HA so I can start over? Thanks again for your time!

rccoleman · January 29, 2022, 8:11pm

Same as with any integration:

But if it was never set up correctly, then it’s not there to delete and nothing to clean up. Removing the code via HACS or whatever method you used won’t help here.

LanaiBoy · January 30, 2022, 6:30pm

Hi, still trying here. I reinstalled Home Assistant, installed and configured HACS. Found and downloaded the La Marzocco integration. Entered Client ID and Client Secret, Username and Password, same error of invalid username and password.

My question is: which username and password? Home Assistant, or GitHub?

Thanks again for your time.
