Wish I had the time to do this in Groovy / natively...
But for now- I'll run this on a raspberry pi and have it interact with Hubitat via the Maker API.
Sets lock codes to the last 4 digits of a guest phone number and also changes the mode at your defined check in time.
Deletes the code and changes the mode at your defined check out time.
Requires nodejs and ideally something like pm2 to keep it running full time.
This makes me wish I had a smartlock on our cottage. 
Thanks for adding more cool stuff to the HE community!
I would love to see a phone interface for that 
I could give it a webserver that would let you set the config and see schedules ... hmmm
Oooh.... That could be good. While I wouldn't use it for Air b&b, I would use it for letting people into my house while were gone and service people...
Hubitat already has a lock code manager app you can use to add/remove codes from locks.
Yeah but it's a pain.... Doing it through a web page or an app would certainly be cleaner... I would also be willing to paypal for the cause 
Sorry, that's not something I will tackle
This is awesome my wife and I are starting our first experiment with AIRBNB, and I did not want to have to pay 40.00-100.00 a month to give a remote code, Thank you for putting so much work into this. would this work with Kwikset zwave locks or just Schlage locks?
It’ll work with any lock that works with Hubitat and supports the commands to set and delete keycodes. Kwikset should work.
What @aaiyar said.
This has been running on a pi at my airbnb for several months now, working great. I have no idea if anyone else is using it, would be great to get additional feedback!
I do too….this is really cool and would be an amazing addition.
I have 10 STR's and I need a solution since the deprecation of Groovy and RBoy's demise. This has inspired me and I am going to give a shot setting up my locks on the Hubitat. Would you mind sharing with me the exact model of raspberry pi you would recommend for this? I assume the locks/hardware and extender/repeaters I used previously should still be functional here. What other hardware is required for implementation. Thanks in advance for your help!
