@megagprime
Did you ever figure this out? I’m having the same issue

[megagprime]

@Nneuland nope, still no dice. building a new mm now, will update

@megagprime @Nneuland depending on the board firmware, the vcgencmd may or may not work

this was reported and worked thru in the fall.

@sdetweil hi there, i still dont see a fix or alternative workaround. The commands themselves work i just cant get it to work with cronjon :(

[sdetweil]

@megagprime what user is cron executing them as?

what user do you use when testing?

cron is root by default unless u add another parm for the username

[megagprime]

@sdetweil i use sudo for cron and root vcgencmd display_power for the command.

no idea if i am doing this right but like i said, i used to work lol

[megagprime]

@sdetweil i use sudo for cron and have tried root and just the vcgencmd, neither work

[sdetweil]

@megagprime I think vcgencmd needs a DISPLAY env variable

[megagprime]

@sdetweil yes i use vcgencmd DISPLAY_POWER 0 or 1, like i said those commands work just fine just not in cron
