While waiting, you can easily use this:
https://github.com/iz3man/duet3d/blob/main/duet3d.yaml

Just add the lines to your configuration.yaml, modify for your printer and restart HA.

@pkos Thanks! But I don't think this is compatible with RRF 3 anymore
@izeman (hoping this is the right user ^^)

@nikscha It works I've been using it for ages now, although I don't have a very elaborate layout. I mostly have HA watch hotend temp and once it's been at 45C for 2 minutes after a print - it switches the printer off.

My code is as follows:

  - platform: rest
    name: Voron_24 Status
    resource: http://<ip_here>/rr_status?type=3
    value_template: "{{ value_json.status }}"
    json_attributes:
      - temps
      - fractionPrinted
    force_update: true

  - platform: template
    sensors:
      voron_24_head_temp_current:
        value_template: "{{ states.sensor.voron_24_status.attributes.temps.current[1] }}"
        friendly_name: Hotend Temp
      voron_24_bed_temp_current:
        value_template: "{{ states.sensor.voron_24_status.attributes.temps.current[0] }}"
        friendly_name: Hotbed Temp
      voron_24_print_percentage:
        value_template: "{{ states.sensor.voron_24_status.attributes.fractionPrinted }}%"
        friendly_name: Print progress

And this is how I put display it in Lovelace.

The important bits here (if you know this, forgive me, if not - maybe it will help) - is to keep the naming consistent. HA will convert the name from the first sensor into an entity_id.
So in my case, here it reads Voron_24 Status. HA will take it, convert it internally to voron_24_status and this is what you use below in the actual sensors.

And since I am waaaaaay too lazy ( ) I am going to wait for MQTT to come along before solving issues like not zeroing out of entries when the printer is off

See if that will work and if you get stuck, ping me and I'll be happy to help.

@nikscha I could not make it work either using RRF3.
I ended up modifying another integration to make it work with RRF 3.
You can find it on my repo :
https://github.com/repier37/hass-Duet3D
Basically I just added authentication to the integration I forked to be able to retrieve data.
It is still using the rr_status command that is planned to be removed in RRF3.5 if I recall correctly, but it should work with earlier version. It should not be too hard to move to rr_model as it should only be changing json parsing.

@repier37

Many thank's for your work!

Hopefully we can expect a update do see the RRF 3.5 working too.

@repier37 just installed your plugin but it doesn't seam to connect to my printer (6HC/v3.4.5 with SBC).

If I send a manual http request it seams like I get access without a password.
http://10.0.0.68/machine/connect?password=

Any ideas what I might have done wrong? All sensors are setup, but values do not change.

  duet3d_printer:
    host: !secret duet3d_host
    name: !secret duet3d_name
    password: !secret duet3d_password
    number_of_tools: 1
    bed: true
    sensors:
      monitored_conditions:
        - 'Current State'
        - 'Temperatures'
        - 'Job Percentage'
        - 'Time Elapsed'
        - 'Time Remaining'
        - 'Position'

Reine

Seams like rr_status has been deprecated in v3.4.5, http://10.0.0.68/machine/Status works though so for this to work with the current version of RRF some work needs to be done on this integration. unfortunately I'm not a Python dev.

Btw, is there a websocket or webhooks that can be used or can we only rely on polling updates?

Lyr3x

Hey folks,
i picked this topic up yesterday and refactored the integration to make it work again with the new /machine/status endpoint.
https://github.com/Lyr3x/hass-Duet3D

Not happy yet with the position entity and the fact that there is no proper config flow and entities are not attached to a device. I will work on that in the next days. Might take some time as I need to dig into that to understand how custom components are built and what the spaghetti code in the integration is doing
I removed the job percentage yesterday temporarily to get this out of my way, because there is not such attribute, but I already spotted that it can be easily calculated with the file size. Contributions are welcomed!

I also removed the password property, as this is not needed for the endpoint. Furthermore, I might need to set up a proper session when the integration has maybe a service to send G/M codes as well. We'll see.

Hope that it is of some help for you as well

LOL. Looking for a way to get MQTT running on Duet-Wifi board, find this thread, and then a link to MY github

Btw: This is still using perfectly fine with the latest betafirmware

And I found this github for MQTT integration which gives basically the same info - but haven't tested yet, as I'm waiting for native MQTT support before I start ripping everything apart again.

@Lyr3x good work, wow! I'll check it out in the next few days!

Marshalldog

@izeman Looks Awesome
how did you get the controls for PLA and that switch into HASS?

Lyr3x

@izeman this is only working if you are not using SBC mode if I am not mistaken.

I worked on updating the integration to work asynchronous without blocking requests, which is working fine now (still need to merge).
There is quite some rework necessary to get config and options flow running, but I finally understood how the flows should be implemented. Can’t give a timeline yet though.

Configuration via configuration.yaml is working fine including time elapsed and remaining. I also added the progress sensor back and calculating the progress via total layers and printed layers.

nikscha

@Lyr3x I'm gettting an error when setting up the integration, could you help me out?

I have two printers, one running Duet Wifi 2 without SBC (RRF 3.4.5), and one running a Duet 3 Mini5+ WITH SBC (RRF 3.5.0beta3).
However both gave the same error as above. Navigating to 'printerip'/maschine/status also returns the json, so I doubt the issue is related to the printers? What else can I try? It might be noteworty that I run HASS on Docker?

Lyr3x

@nikscha as Said before the config flow is not working. You need to configure it via the configuration.yaml at the moment

nikscha

@Lyr3x Ohh I see. Fair enough. I'm still having problems though:
I added the follwoing to my config:

# Duet Integration
duet3d_printer:
  host: !secret duet3d-host
  name: !secret duet3d-name
  number_of_tools: 1
  bed: true
  sensors:
    monitored_conditions:
      - 'Current State'
      - 'Temperatures'
      - 'Job Percentage'
      - 'Time Elapsed'
      - 'Time Remaining'
      - 'Position'

I also added the entries for host and name to the secrets.yaml.

However HASS wont restart:

Lyr3x

@nikscha oh the readme is still wrong. It is not Job percentage but Progress

nikscha

@Lyr3x that did the trick, thanks!
The integration is working well, can I do anything to test it for you?

Lyr3x

@nikscha thanks will let you know! Of course if something is not working as intended don’t keep it to yourself.
