VCGENCMD error

[cjmjmartens]

The problem

I use the following command to display the current version of the Raspberry firmware (RPI4). Since the upgrade to HA 2024.2.0, I receive the following error:

Command failed (with return code 1): sh -c 'ts=$(/usr/bin/vcgencmd bootloader_version | sed -E -n -e "s/timestamp (.*)/\1/p") && date -u -d @$ts -I'

What version of Home Assistant Core has the issue?

2024.2.0

What was the last working version of Home Assistant Core?

2023.1.6

What type of installation are you running?

Home Assistant OS

Additional information

In June '23 I reported the same error. Stefan Agners replied:

"Note that when you use a command sensor, this command is executed in the context of Home Assistant Core, which is not the same Home Assistant OS. So this is not a OS related issue. That said, it seems that vcgencmd moved from /opt/vc/bin/vcgencmd to /usr/bin/vcgencmd, presumably because Alpine Linux package raspberrypi-userland changed the path of that program between v3.17 and v3.18. So you'll have to adjust the path of your command."

where or how do you use this command?

[cjmjmartens]

I have added this command to configuration.yaml:

- sensor:
    name: RPi Firmware
    command: |
      sh -c 'ts=$(/usr/bin/vcgencmd bootloader_version | sed -E -n -e "s/timestamp (.*)/\1/p") && date -u -d @$ts -I'

[mib1185]

is this the full configuration for this sensor? i still can not recognize the integration of this sensor?

[cjmjmartens]

Yes, this is it. Before the upgrade to 2024.2.0, this sensor reported "2023-05-11" on the dashboard. BTW: it looks like the vcgencmd command does not exist anymore in the /usr/bin folder. Maybe this command has been moved to another folder, but I am not able to find it.

Hi, I've encountered a similar problem with the sensor since I upgraded to version 2024.2.0. my sensor: for GPU temperature:

• sensor: name: GPU Temperature command: "/usr/bin/vcgencmd measure_temp" unit_of_measurement: "°C" value_template: '{{ value | replace("temp=", "") | replace("''C", "") }}'

stopped working In HA Core log i have error messages like this: [homeassistant.components.command_line.utils] Command failed (with return code 127): /usr/bin/vcgencmd measure_temp /bin/sh: /usr/bin/vcgencmd: not found

from SSH shell i run this command without any problems

HA OS does not include vcgencmd (or at least not on my own) so it's not an issue with command_line really. You would have to make an issue on HAOS repository as the issue is really not here. Thanks for understanding 👍

[cjmjmartens]

@gjohansson-ST, thanks for your reaction.

@rusandko, I have created a new bug report in the HA OS section: https://github.com/home-assistant/operating-system/issues/3172

[agners]

HA OS does not include vcgencmd (or at least not on my own) so it's not an issue with command_line really. You would have to make an issue on HAOS repository as the issue is really not here.

The command_line integration runs commands inside the Home Assistant Core container, even on OS. So this utility is missing in the container. The board/machine specific utilities are installed as part of the machine specific Dockerfile in machine/ in this repository. So I've reopened the issue here.

But indeed this is not really an integration issue, so I've adjusted the label accordingly.

It seems that this is caused by the Alpine 3.19 upgrade. The package raspberrypi-userland in 3.18 contains vcgencmd, whereas raspberrypi-userland in 3.19 doesn't contain it anymore. It seems the package raspberrypi-utils-vcgencmd needs to be installed instead.

This effectively is a fallout of #107175. I create a PR to fix this.
