Reading Chamber Temperature

repmanrepman
in General
I added a chamber temperature sensor and want to monitor that.
I added the sensor in klippers printer.cfg and via the console the M105 command shows the right temperature:

Send:22:17:04.429: N39 M105
Recv:22:17:04.430: B:25.5 /0.0 C:25.7 /0.0 T0:23.1 /0.0
In Repetier-Server I added the "heated chamber" tool and after that the symbol for heated chamber appears in the printer bar.
But the shown temperature is still 0.0°C

How can I display the right temperature? Do I need a special alias?
Regards

    Yes, you need to set the name you gave it in klipper config. Guess you added it as generic heater so set the name in server so it knows which one belongs to the chamber. Since this is freely definable we need that info.

    Sorry, no success. As I just want to monitor the chamber temperature I added a sensor.
    In my printer.cfg:

    #####################################################################
    #    Chamber
    #####################################################################
    [temperature_sensor chamber]
    sensor_type: ATC Semitec 104GT-2   #ATC Semitec 104GT-2 #NTC 100K beta 3950
    sensor_pin: PC3
    min_temp: 0
    max_temp: 100
    gcode_id: C

    This works from the console:
    Send:9:08:58.242: N20 M105
    Recv:9:08:58.243: B:22.8 /0.0 C:23.7 /0.0 T0:20.3 /0.0

    So the C: is the chamber temperature.

    In the RS PrinterConfiguration/Tools/HeatedChamber:
    Alias: Chamber
    Name in Firmware: C     (I also tried chamber, Chamber, C:, C0)

    I always see 0.0′C at the box icon in the printer status panel.

    What to do?

    This is a problem in server if you do it this way. We assumed chamber is defined with
    [heater_generic chamber]

    I have updated to pi dev version to also listen to [temperature_sensor chamber].
    Login via ssh and run
    installDev
    and see if it works. Currently untested due to missing printer with that config, but quite sure it will work then.

    Name in firmware in your case should be:  chamber
    to match the section in config.

    Where can I get that "installDev" from and where should I put it?
    I don´t have that script/program.

    It is part of our newer pi images. Here the source so you can run the same commands with copy and paste

    #!/bin/bash
    cat /proc/cpuinfo | grep ARMv6
    IS_V6=$?
    cd /home/pi
    rm Repetier-Server-dev.deb
    if [ "$IS_V6" == "0" ] ; then
      echo "Raspberry Zero or 1 detected, installing armel version..."
    else
      echo "Raspberry with v7 or newer command set found. Installing armhf version..."
    fi
    sudo dpkg -i Repetier-Server-dev.deb
    rm Repetier-Server-dev.deb

    Ok, I see! Because of my some kind of outdated touchscreen I'm  still on the buster image.
    I have updated to pi dev version to also listen to [temperature_sensor chamber].
    Login via ssh and run
    installDev
    and see if it works.

    Works! Thank you repetier!
