v0.21a code:
(AC cooling unit only, no heater so far but probably easy to implement. Requires air conditioner power switch, two motion sensors, two thermometer sensors)
Place the following code into your homeassistant\configuration.yaml file
homeassistant:
packages:
pack_1: !include motion_thermostat_package.yaml
Then copy and past the following code into a file named homeassistant\motion_thermostat_package.yaml and follow the directions in the code comments
### Motion Sensor Thermostat v0.21a by Wheezy ###
### How to modify this thermostat code for your own two room setup:
# Copy this code into a file named motion_thermostat_package.yaml. Rename the following variables to the names of your own sensors (find and replace with CTRL-H) inside that text file.
# Room 1 name: Livingroom <---- MATCH CASE! If doing CTRL-H / Find-And-Replace
# Motion sensor 1: sensor.sn1_pir
# Temperature sensor 1: sensor.sn1_temperature
# Room 2 name: Bedroom <---- MATCH CASE! If doing CTRL-H / Find-And-Replace
# Motion sensor 2: sensor.sn2_pir
# Temperature sensor 2: sensor.sn2_temperature
# AC unit off: script.ac_poweroff <---- You'll need to write a script in your configuration.yaml (or here) that turns off your ac power (or uncomment the ones I wrote below). You can also use a switch here if you like.
# AC unit on: script.ac_poweron <---- You'll need to write a script in your configuration.yaml (or here) that turns on your ac power (or uncomment the ones I wrote below). You can also use a switch here if you like.
#
# Then copy-paste the following code into your configuration.yaml under the homeassistant: heading
#

# packages:
# pack_1: !include motion_thermostat_package.yaml
#
### How to add more rooms:
# This thermostat is made for two temperature + two motion sensors (two rooms), but more rooms/sensors can be easily added by ...
# 1. Changing the "Inside temperature" sensor to average more than two sensors
# 2. Adding that extra room name to "input_select.last_room_with_motion"
# 3. Modifying the automation by copy-pasting another pair of Adaptive AC Mode "A/C on if hot" and "A/C off if cool" conditions for another room
# 4. Adding another "automation.store_motion_sensor_X" (and then hiding added automations from the main view to keep things looking pretty)

Let me know if I forgot any components. There’s a ton of them
edits: Implemented package format for easier installation, cleaned up thermostat card, added picture, updated automation triggers for HASS 0.47.0, fixed bug in optional automations, consolidated automations into one automation. If someone wants to turn this into a python script, feel free to!
Cheers to these people for code ideas/examples/help:
v0.1a code
(old, but here just in case I broke something in the new version):
I got it working! Ok, so it turns out I did need the livingroom / bedroom tags on the turn off switch, but that was a great idea and it was really nice that you helped out. I think you gave me motivation to look at this again 
It turns out I needed several triggers that were ALSO conditions at the same time. WEIRD! I don’t pretend to know how this works, but I’m glad that my test cases all work. Here’s the MEGA routine with code for all the components (except hardware switches) that it needs.
## How to modify this thermostat code for your own two room setup:
# Rename the following variables to your sensor variable names (find and replace with CTRL-H)
# Room 1 name: Livingroom <---- MATCH CASE! If doing CTRL-H / Find-And-Replace
# Motion sensor 1: sensor.sn1_pir
# Temperature sensor 1: sensor.sn1_temperature
# Room 2 name: Bedroom <---- MATCH CASE! If doing CTRL-H / Find-And-Replace
# Motion sensor 2: sensor.sn2_pir
# Temperature sensor 2: sensor.sn2_temperature
# AC unit on/off switch: switch.ac_power
#
# Then copy-paste the following lines into your setup under the appropraite headings
# (example:
# group:
# thermostat:
# name: "Thermostat"
# entities:
# - input_boolean.thermostat_control
# - input_slider.thermostat
# - input_select.thermostat_ai_mode
# - sensor.last_room_with_motion
# should go under your "group:" area, without copying the "group:" header part of the above code.)
## How to add more rooms:
# This thermostat is made for two temperatre + two motion sensors (two rooms), but more rooms/sensors can be easily added by ...
# 1. Changing the "Inside temperature" sensor to average more than two sensors
# 2. Adding that extra room name to "input_select.last_room_with_motion"
# 3. Copy-pasting/modifying another pair of Adaptive AC Mode "A/C on if hot" and "A/C off if cool" automations for another room
# 4. Adding another "automation.store_motion_sensor_X" (and then hiding added automations from the main view to keep things looking pretty)
