This blueprint is based on the work of Sam04.
I needed to add the speed level (percentage) for a mid temperature and a max temperature.
I have clearly declared the use of the fan service instead of the homeassistant service to turn/turn off on or control the speed.
Besides the Inside temperature threshold at level 1 of your fan (33%), there are a Mid-Temperature for the level 2 of your fan (66%) and a Max-Temperature for the level 3 of your fan (100%)
This was done for my personnal use and I might enhanced it.

name: Automatic Fan 3 Speeds Set Control based on Temperature
description:
"## Fan ON/OFF and set speed (3-speeds) Automation based on temperature,\
\ outside temperature.\n\nFan turns on if the following conditions are met:\n\
\ temperature inside greater than your set threshold value\n temperature outside\
\ is lower than your set maximum value (to prevent turning the fan on in winter)\n\
\nAnd the Fan turns off if the following conditions are met:\n temperature inside is\
\ lower than your threshold value minus the hystersis value\n What the automation\
\ **NOT** observes:\n manual fan control. Adapt the given values too your needs.\n\
\ If you manually turn the fan on and the inside temperature is below the threshold\
\ your fan will turn off soon.\n\nWhat you need:\n a fan entity. if you control\
\ your fan via a switch entity (via smart plug for example) you can create a template\
\ fan entity.\n sensor entities for inside and outside temperature. (if you want\
\ to use the weather domain than create a template sensor from the temp attribute)\n\
\ Inspired by b-0s based on the work of Sam04"
