    The manual says using picoolfan4 at an i2c address other than 0x60 requires an specific firmware (for each one, 0x50, 0x40, 0x30…) and all python scripts adapted to it that is, consecuently reading from 0x50… etc, not from 0x60. As I’m using a fixed i2c address sensor (0x60) I would need one of this new firmwares. Is it available somewhere now or will it be soon? Thank you.

      Hi,
      This firmware can be re-compiled on demand at any time, please advice what address you need to have in order send you firmware recompiled to your request, Python scripts you should do your self but it is a very easy task. Please advise by email to support@pimodules.com what I2C address you are interesting on. We will re-compile the firmware in 5 minutes and send you. We can also change permanent the temperature threshold, to your needs as default set up.
      Kind Regards
      Ioannis

        Hi, thank you very much for such a quick response and offer!,
        For my needs, changing the base i2c address to 0x30 would be great. About ttemp, default 50º and fixed maximun possible to 75º in the latest firmware 1.04 it is fine. Of course, I’ll take care of adapting python scripts as well as any shell script using i2cset… No problem at all.
        Anyway I’m going to advise all this to that support email provided.
        Thank you again in advance.
        Kind Regards
        Fernando

    I wish there was an option for a fallback plan, when – depending on the mode used – the CPU Temperature is not updated or the fan speed is not set in the last 5 minutes.
    So either go back to the internal sensor or use a fixed fan speed.
    That would resolve a possible issue of the system overheating when the monitoring process has died and is not restarted…

    Using this i2c communication as a sort of watchdog that would pull a pin low (which can then get connected to the reset pin on the pi) may also be a helpful addition to the firmware…

      Hi,
      Thank you for your email!
      We are currently updating the firmware, it is good time to implement your idea. Could you please explain in more details your idea to be sure that I understand it properly and go to implementation. The controller we are using in the PiCoolFAN4 is very small memory footprint, but there is little bit free space to add some lines of code (or remove other parts and add your idea)
      Can you please describe in more details your idea on our support email support@pimodules.com
      Kind Regards
