I had this setup on a Dell monitor and it worked perfectly.

I just installed a new monitor - a Lenovo Thinkvision P32p-20

After starting the sensor works as it’s supposed to, waking the monitor when someone passes by and sleeping after 60 seconds of inactivity.

But after a while, the monitor does not wake from sleep. The MM instance is running fine (I can look at the dispaly from a remote browser).

The monitor is in powersave mode (amber LED)

The only way to wake the monitor is to touch a button on the monitor’s control panel.

The monitor has no configuration options for powersave or sleep.

Any suggestions on how to fix this?
