Welcome to the Forum, @agert! 
I get that the Extreme Battery Saving Mode is less than ideal because it requires an actual touch to “wake” Palm Lock for scanning, and I know that they’re aware of the issue as described in Palm Lock Battery Drain (which links to a related topic if you read through that). The 1.2.0 firmware was released to the beta channel ~2½ weeks ago, and that’s supposed to include improvements to battery management for Palm Locks behind storm doors, so I’d be on the lookout for that once it graduates to the production channel.
I don’t believe so, at least not anything currently available beyond the Auto setting in Battery Management. I’ve never seen a feature like that exposed as an Automations Action, and if something like what you’re suggesting was already possible, then I would expect to see it in Automations within the Wyze app. Given the number of outstanding requests for Automations Actions and Triggers that already exist within the relevant Wishlist topics, I wouldn’t imagine this would be a priority for development, and I’d guess they’d say that’s what the Auto mode is for in the Battery Management setting anyway.
