Most of these automations have come over from Hubitat + some special glue code I wrote, but I have since migrated to HomeAssistant, and the way I've implemented things is a bit different than others, so here's how I did it.
I've got 60+ devices in the house - zigbee, zwave, lutron. I use the HomeAssistant zigbee & zwave USB dongles. I run it on a pi 5 w/ ssd. I have zwave locks.
I could use keymaster and Rental Control add-ons, but I hear that keymaster creates hundreds of entities and is overly complex, and Rental Control depends on it. So I am using the much simpler Lock Code Manager.
First, I have "House Modes" defined: Away, Arriving Soon, and Home.
I have an automation that will run scripts based on the mode change.
Arriving Soon script:
- Turn on water heater (it takes 10 hrs to warm up - hybrid heat pump water heater)
Home script:
- Turn on lights
- Turn on water heater (in case we never transitioned through Arriving Soon mode)
- Set HVAC
Away script:
- Put water heater back into vacation mode, reset HVAC temperatures, turn off lights.
Second, I have the HA Remote Calendar integration pointed to my airbnb ical. This brings my reservations into the HA calendar.
Third, I have an automation that runs at 12:01AM, 10:30AM, and 12:30PM every day.
If the script executed at 12:01AM and it's check_in_day, change mode to Arriving Soon
If the script executed at 10:30AM and it's check_in_day, change mode to Home and add lock code to slot 7 on 2 locks
If the script executed at 12:00PM and it's check_out_day, change mode to Away and remove lock code from slot 7 on 2 locks
I get the last 4 digits of the guest phone number from the calendar event.

Of course, that's just my calendar control. I've got a bunch of other automations to..
- Turn off the (zigbee) water valve if any of my water sensors get wet (zigbee water sensors),
- Notify me if a smoke detector goes off (FirstAlert Zwave Smoke Detectors),
- Allow the guest to turn on the whole house fan only if a window is open (and turn the fan back off if the outside temp rises above the inside temp),
- Notify me if a vehicle enters my driveway (Dakota Alert vehicle sensor hooked to a zwave door sensor),
- Let the guest open up the garage by typing their code into a xfinity zigbee keypad outside the garage (compares action_code to the codes programmed into the front door lock).
