The ZMK + Nice!Nano relies on deep sleep mode after 15mins of inactivity, saving efficiently battery charge. The power draw on nice!nano v2 during deep sleep is around 20uA, which is about 1mAh every 2 days. So you can consider that also as an automatic power on/off.
More on power management here: ZMK Docs
After 15 minutes of inactivity the keyboard goes into deep sleep mode, saving efficiently battery charge. The power draw on nice!nano v2 during deep sleep is around 20uA, which is about 1mAh every 2 days. The battery on slave side will last more time than on the master side, as it consumes less energy.
Battery charging time ( hours ) = Battery capacity ( in Ah ) / Current supplied ( in A )
Li-Po Battery capacity: 110 mAh = 0.11 Ah
Current Supplied by nice!nano = 100 mA = 0.1 A
110 mAh Battery charging time = 1.1 Hours = 0.11 Ah / 0.1 A
โข Nice!Nano come with ZMK default keymap
You can fork these keymaps, change the keymap to your needs and flash the controllers anytime.
โข Nice!Nano works wired and/or wirelessly. Requires 3.7v Li-Po battery for wireless mode. Supports ZMK Firmware.
If you use:
โข Pro Micro: VIA
You need to flash your controllers with the via keymap first time for it to be recognized on VIA. This is needed to be done only once. After that you can change your layout on the go, without the need to flash your Pro Micro again. The downside is you can’t use some more advanced features of QMK

I haven’t tried it so can’t say much about it, but i have seen people using it so it works.
