For security reasons, I would not use motion or presence sensors to open or unlock any exterior door. I might use these to Lock or Close a door. Rationale: There are still too many 'failures' in this for a security disable reason. I would want 100% assurance from a single method or use two independent methods that must both be in the proper state.
Amazon and Google are great methods to control these devices. I have Echo Auto and I just tell the device to open / close the door - using an access code for opening the door. On closing, I will have an automation to turn off house items, set-back thermostat, etc. On open, reverse and if after dark, turn on exterior and interior lighting.
