I have had the same problem with the brand new E1. The PIR button is missing, that I so dearly cherish on my Argus Eco cameras.

The "Scene-Function" now works well as a substitute, however, I still hope for adding a power-off-or-turn-off-motion-detection-button like the "PIR" button on my Argus Eco cameras.

Anyhow: Thanks for pointing out that "Scene Mode" which I will use in the meantime.
