Autoshutdown und reboot for Recordings

darmflorist

I dont want to let the computer ran the whole day, until a recording is coming up, because it uses so much power. Is there a possibility to shutdown the computer while nothing is recording and reboot when a recording is coming up.
Earlier I used "PVR Recordning & Manger" but this needs kodi, and i cant kodi get running after an upgrade to noble numbat (24.04 ubuntu). So is need another possibility to do, what the script does which is not working anymore.
Maybe shutdown when i press the key f12 and wake up on the next recording.
Any help would be nice

Thx Darmflorist

There is no way to do this within TVH only.

You would need to write a script that looks at the start times for upcoming recordings, plus any EPG grabber cron schedule, and then put the computer to sleep until then.

Is there an easy script, that i can use and that i can cron schedule?

Just install the following python-program in a virtual environment:
https://github.com/languitar/autosuspend
https://autosuspend.readthedocs.io/en/v7.0.2/installation.html#manual-installation

and create a systemd-service to autostart it:

malvinas22 is there any integration with TVH for that autosuspend program? How does it detect when to shutdown and resume depending on scheduled recordings?

There is a config-file called autosuspend.conf:

# A generic check which queries a configured URL and expects the reply to contain$
# The returned XML document is checked against a configured XPath expression and
# in case the expression matches, the system is assumed to be active.
[check.Tvheadend]
class = XPath
enabled = true
url = http://192.168.1.41:9981/status.xml
# xpath = /currentload/subscriptions[number(.) > 1] | /currentload/recordings/recording/start | /currentload/re>
xpath = /currentload/recordings/recording/status | /currentload/recordings/recording/start | /currentload/recor>
username = kodi
password = kodi

# Comparable to XPath, but expects that the returned results represent the
# wake up time as a delta to the current time in a configurable unit.
[wakeup.XPathDelta]
enabled = true
url = http://192.168.1.41:9981/status.xml
xpath = //recording/next/text()

# xpath = /currentload/recordings/recording/next/text()
# xpath = //recording/next/text()
# xpath = /currentload/recordings/recording/text()
# or xpath = /recording/next/text()   ????
username = kodi
password = kodi
