  • More Linux permission updates.

  • More support for HAT version 1.1

  • Refactor internal pumping code. There’s more flexibility that allows for solving parts of #384. Including:

    • creating cleaning scripts
    • creating cycling scripts, that also respect the rates of specific pumps vs waste (so that you don’t overflow if addition rate > removal rate)

    Namely, new functions circulate_media and circulate_alt_media are introduced that will cycle both a pump and the waste pump simultaneously. The waste pump starts first and ends second.

  • Exposing the above routines in the UI, and improvements to the dosing UI:

Just tried updating from build 23.2.8.dev

I got this error, not sure if it is important:

Mmm right. That’s the result from an older build. Easiest solution:

sudo nano /usr/local/bin/update_ui.sh

And delete the line that looks like pip3 install -r ....

While your on the command line, I suggest running pio update ui again to confirm it works.
