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).
