Wyze Sense alerts only when I am not at home

Sense notifications toggle is being added to Shortcuts. You can read about that here: On/Off Toggles/Schedule for Wyze Sense sensors - #18 by WyzeMike.

To control this automatically when you leave home, you’ll need geolocation triggers for the Shortcuts feature. You can vote for that here: Add More Device Triggers for Wyze Rules.

You could also control this via IFTTT if per-device notification control were added. You can vote for that here.
