[TheFreeman]

Current Situation

Hi SwitchBot Team 👋

I am an active Home Assistant user. The Home Assistant community is huge and growing rapidly – with millions of users worldwide.
Most of us make buying decisions strongly based on Home Assistant compatibility.

Proposed Change

Requested features

• Battery level for Lock Ultra, Keypad Touch Vision, Hub.
• Tamper / intrusion alerts if device is removed or manipulated.
• Unlock method attribute (App, Face, Fingerprint, NFC, PIN).
• Last unlock person/method for automation logic.

Benefit

Improves security, reliability, and automation depth.
These sensors are standard in other smart lock ecosystems and would make SwitchBot more competitive.
