Screen off - question RS150B

Dear

Is it possible to turn off the screen from the device? I know you can from the app.
Thanks in advance for your answer.

And overall very good work.
Thank you

Which device?
On the RS130 if you press and hold the button on top farthest right for a few seconds it give you choices to turn off, etc. and one of the choices is LCD Off or similar.

no you can’t do it from the hardware (device) on 150b

I can do it. It works.
