@Dean105 I have 3 August locks w keypads and Connect.
-Does the Keypad work without Connect product and pay subscription or do I need that too?
The keypad does not require Connect to work with your August Smart Lock.
There is no subscription required, or any ongoing costs associated with using the August system.
- Does Airbnb Integration automate the issuance of unique codes to guests?
If by "codes" you mean does it set up access to the lock automatically, then yes. However, if the user does NOT install the app, the automatic setup does NOT automatically set up the keypad for the guest (more on this later). August is aware of the issue and is even now working on adding automatic keypad codes for the guests.
- What happens if WiFi goes down - does Keypad store codes such that they can get in during their stay
Wifi is not required at all for the August Smart lock and keypad to work. The only use of the Wifi is to allow you to monitor and/or reprogram the lock from far away.
- How frequently does Keypad communicate with August/Airbnb/web?
I really don't know how the magic works, but it actually can work fully without any internet access at all.
If the guest uses the app, they can have access instantly, even if the August Smart Lock itself has no internet access. It is black magic indeed.
If you *do* have Wifi enabled with Connect, you can re-program the lock and keypad remotely and provide access instantly yourself using the app. You can even lock and unlock the door remotely, if you have Connect.
So about the keypad codes: Until August releases the promised "automatic keypad codes" update, you do have to add the keypad codes manually. What does get set up automatically is access to the lock via the app. And to add the keypad codes remotely you do need Connect.
