External Power Control toggle/turn off not respected by right side of split

[razlani]

So I'm reading online that externally turning off power affects both halves of the split equally.

Cool not super nuanced but I can live with that: my goal is to have both LCDs connected at all times, but just flash them on to see if they need a charge using the toggle shortcut (and then resetting them both, given an ongoing zmk issue preventing lcd on after a 'sleep').

Issue is that only the left (and main) side seems to respect the toggle.

The only thing I can do to get the right side to turn off is use a hack of setting a very low figure of

CONFIG_ZMK_IDLE_TIMEOUT
As per this. Right side of split seems to respect this setting, but it's a crap solution as my right side battery will still take a beating.

Any one know of how I can troubleshoot this issue, assuming it is one and not just PEBCAK?

Noteworthy that I'm using 2x n!n (version 2) and miryoku-zmk for config.

Flashing via west,
west build -p -b nice_nano_v2 -d build/right -- -DSHIELD=corne_right -DZMK_CONFIG="/mnt/c/Users/privy/git/keebs/miryoku_zmk/config"

West version: v0.14.0

And then merging mouse-ftc on top.

You might be running into the #1494. Miryoku was updated recently to not rely on mod morphs for these by default, see https://github.com/manna-harbour/miryoku_zmk/#global-shift-functions.

Closing this as a duplicate of #1494, without a response.
