Bathroom light and fan automation

I created this from an automation I have been using for awhile. Its not made in the traditional way most lighting automations are done. I prefer to use timers as they seem to be much more reliable especially if you are tinkering with automations alot. This method has proven to be pretty reliable in turning off the lights and fan.
This blueprint requires 2 sensors. A motion and a door/contact sensor.
It also requires 2 timers. One for the light and one for the fan.
It operates under the assumption that if the door is closed, the room is occupied. If it is occupied, we are assuming that you are doing something that may require the fan to be turned on. The light and fan will stay on as long as the door is closed.
You can set the time to turn on the fan after the door is closed. The fan timer will not activate until the door is closed.
The other timer selection is to choose the delay after last motion to when the lights turn off.
2 triggers can start the countdown trigger. Last motion, and opening the door. I did that for redundancy in case one trigger fails. Most of the time last motion wins out.
This is my first blueprint…

New to HA

The light timer and fan timer are drop down options after importing the blueprint. But only option I am getting for both is “no matching entities found”.

How do we go about setting up these entities?

Also, I have the Kasa Motion Dimmer switch, I wasn’t getting that in the drop down for the Motion Sensor part, but edited in YAML and pasted the product name manually over there and showed up now in the box, hopefully it’ll work!

You need to create those timers in the helpers menu.
Devices and services, then helpers at the top.
