Assume your Switch is on FW 17?
Theres a newer version of the Module for it.
https://github.com/retronx-team/sys-clk/releases/tag/2.0.0-rc
Its a bit hidden when you just click on Release on the github, because its a pre-release still.
You guys on Emulator? Codes requiring button presses dont work on them. You'd need to use seperate codes for on/off.
Think theres one linked somewhere in the thread.
