[RPi] Argon ONE Control Add-on (Support Thread)

    Quote from Da Flex

    I don't see any related errors at the log. Maybe you should create another one, because logging was just activate during that session.

    Ok, I did that, I restarted it several times, here it is:

    • Login by SSH, and use the poweroff command. Does that work correctly?
    • I've seen a Bluetooth error at the log. Not sure whether it's relevant, but disable Bluetooth, and try again.

    myshit ,

    You will need some additional scripts that are part of the Argon Pi addon. Since the add-on was no longer maintained after the initial commit on GitHub, I ported it myself to make it work with LibreElec 10+ two years ago. I haven't touched this since then, but it still works with LibreElec 11 and you can also configure the fan speed.

    I'd have to look up the git repo and installation package. If my newly created user allows this at all, I could make it available here.

    That sounds really good. If I could also control the fan speed it would be a nice bonus since this doesn't work too (but since the CPU load is not usually very high, the passive "cooler" (case) handles ut). So, you're saying, that it could resolve the full shutdown problem? If you would be so kind and post the repo and some instructions with it i would really appreciate it.

    Yes, the poweroff command is working ok via SSH. I don't think that bluetooth is has something in coincidence with it

    So shutting down from GUI hangs, but shutting down from SSH works as expected.

    Both tested without the Argon One case. Are those statements correct?

    If yes, then I'll ping the devs to have a look.

    It shutdowns ok with SSH or from GUI. The only thing is the red LED that still keeps turned on preveting me from turn the Rpi again back on after shutdown - I have to manually press the button for few seconds.

    I see. Then the shutdown actually doesn't work as expected, because the red LED stays on.

    The cause of such issues is often a file system with errors. Broken file systems can't be unmounted at shutdown. If you only use the microSD for files, then install LE from scratch, or use a repair tool for checking / repairing.

    Hi Da Flex ,

    I hope I can remind me right, because these information are 2 years old... ;)

    There are at least 2-3 revisions of the Argon One case. The newer ones even have an infrared receiver on board. The power-on button is not directly connected to the Pi. In between is a circuit board with a microcontroller. This is responsible for switching off the power supply to the Raspberry after shutting down. The microcontroller recognizes the signal at the power-on button and can also trigger a RESET (different PIN on the Raspberry) by pressing the power-on button twice in quick succession. If you press this button longer than 3x seconds, the Raspberry will be shut down and the power will be switched off after a delay. It may be that this behavior depends on the firmware version of the microcontroller and could be different with the first batch of the casing.

    If you shut down the Raspberry via OS, the microcontroller in the Argon One lacks the information that its allowed to cut the power supply. Therefore, after an orderly shutdown, the red LED at the front, behind the semi-transparent plastic cover, remains on. However, the microcontroller also knows a return channel via PIN on the UART interface. This PIN changes its logic level after shut down of the Pi and the microcontroller starts the process to cut the power of the Raspberry Pi. This has to be configured specifically on every OS and with every startup. It's part of the ArgonForty Device Configuration add-on, for example. Alternatively, there are some other scripts/daemons that do something similar.

    I have a feeling, you want something what's never existed.

    I have 3 RPi's and using with LE for years. And the red LED after shutdown always remains on, and to start again always needs to do a power cycle. That is how the RPi works with LE. It's not like a "normal" PC, with stand-by part in power source and with IO chip always powered, ready to react if the power button is pressed (and with a hidden power consumption in stand-by...).

    The RPi have only a single GPIO input able to force to boot again if is activated with a button.

    If you have concerns about the "LED red light", I think that LED can be disabled in config.txt.

    If you have concerns about power consumption, after RPi "shutdown", the most part it's the power source itself (like any phone charger, have some consumption even if no phone connected), so switching of the main power can be the solution.

    That does the trick :) the red LED turns off after shutdown command from GUI (I didn't test it with SSH), I can turn Rpi back on after that and the fan control also works. All of that is working under LE 11.0.3 version. I want to thank you very much for the solution as well as I want to thank everyone else for their answers, what a great community, I've never seen that before ^^

    myshit,

    You're welcome. Nice to read that it's working for you now.

    I have reviewed the python scripts again. To be technical correct I should revise my posting (#28)

    • the microcontroller supports Reboot (double-tab at power-on button) and not RESET
    • the microcontroller signals 2 different requests (Reboot, Shutdown) at PIN7 of the Pi4 board
    • during shutting down a script sends 2 messages at SMBus (i2C) back to the microcontroller
      - first message : stop fan
      - second message: initiate power off, cut when the serial pin goes 'down'
      More information about this are available here: https://github.com/Argon40Tech/Argon40case

    These things are only working if a service is running in the background to make cycling checks at PIN7 for new message from the microcontroller. The shutdown script is a hook during the LibreELEC OS shutdown: https://wiki.libreelec.tv/configuration/startup-shutdown

    I'm late but give my 5 cents anyways. ^^

    I'm actually doing "both" what's discussed here by the press on a MCE remote with the kind help of an IR-Receiver/Blaster.

    So in the end I always have AC power cut (no standby power) but also have LE shut down properly before cutting the power. To turn my home theater ON or OFF is just one button on the remote and the IR-Receiver/Blaster orchestrates the rest (Turning the AC Plug On, send signals to Screen, Amp, LE Box to turn on or vice versa with proper delay for LE to shut down completely. I don't use/need any scripts in LE for this to work.

    Add-On was update to version 0.0.7.

    Thanks for maintaining this addon its great.

    Using a V3 case with an LE12 nightly and addon v0.0.7, the fan pulses every 20-30 seconds. Is this expected behavior? LE is reporting temps of about 42c and fan thresholds are the default.

    If the on/off frequency of the fan is pretty constant, then I would say it's expected behavior. My power LED (always-on expected) had random on/off cycles without that fix.

    PANiCnz ,

    your are the second which reports this behavior with Argon One V3 in combination with 0.0.7. So there seems really to be an issue within the current code.
    Currently I can't reproduce with my V2 case... it could takes longer to find the root cause.

    As long the CPU temperatur is below the first threshold, the fan should be off. Pulsing is possible if the current temperature is around the threshold. 42c is far away from the 55c default value. I fear I have possibly insert this bug as I switched over to the Argon Register Helper methods, which has a mechanism included to differentiate the firmware versions.

    From the testing with Argon V3 case exists a version 0.0.6d, but this version should only be used with LE12 + Argon One V3 cases, because the commands were changed for the new firmware. I don't know if there are also V2 cases with this type of firmware in the wild.

    Edit: This bug was fixed beginning with v.0.0.8. Please update to a current version of the add-on.

    Yeah its constant. Kinda annoying but not too bad.

    After about 30 seconds of testing this seems to solve the problem. Haven't tested any of the other features but the fan isnt pulsing at this stage.
