Switch off the display - how to ?
As of now I use a pir-sensor to switch the display on and off (hdmi).
But I cannot suppress the screensaver - does not look good .
Via my smarthome system ( fhem ) I could use a remote switch to power the display on and off.
I could do this sending a (URL)-command to the system.
How can I achieve that ?

@howi42 What module do you use for your PIR sensor? Some modules are able to directly control a Relais for the monitors power supply.
Not sure if I understand the issue.
You want to inhibit the screensaver?
I have a script in the startup:
xset -dpms # disable DPMS (Energy Star) features.
xset s off # disable screen saver
xset s noblank # don’t blank the video device
unclutter & # loose the cursor
This works for me on a Pi0 which doesn’t have a desktop, might be different if you have a console loaded at boot.
Others have mentioned installing the screensaver app and using that to inhibit the display blanking.
If you want to switch the display from a phone, try RasPiCheck (available from Google Play) & set up a couple of console commands:
vcgencmd display_power 1 # for on
vcgencmd display_power 0 # for off
you’ll need SSH switched on in the Pi config & know the Pi ip-address.
