9.2.0 - PVR recording and power management

I want my N2 (9.2.0 nightly from early Oct) go to standby when switched off, but wake up for any recordings.

I found PVR recording and power management add-on (https://kodi-addons.club/addon/service.pvr.manager/) which is not in the standard repository.

Anyone has any experience with it, or can recommend anything else?

Thanks
