One of the custom apps I used most on smart things was the dcoffing 3 speed thermostat. It kept my bedroom fan at exactly the right speed per temp. I tried porting it over using the known tricks, but it errors out when trying to create a new automation. Don't suppose anyone has gotten this to work? All the ones ive been able to find are only turning the fan on at a certain temp, and I liked the ability for the fan to increase based on how far above the temp it was.
original source:
You should be able to replicate this functionality in Rule Machine using a temp sensor as a trigger.
yeah I tried, but I had trouble getting it to fire on anything more than just the first temp. I could get it to work with 3 or more rules, but that seems like a invitation for conflict.
Looking at the code, it just seems to use the ‘setLevel’ or switchLevel command, like a dimmer or bulb.
Does you fan have the ‘setLevel’ or ‘switchLevel’ command on it’s device page?
Andy
Should be easy enough to create it from scratch.
Depends really what you want it to do.
I assume this is a cooling fan?
Yeah. I fully accept it could probably be done with the rules engine, but it hurts my brain.
Awww..
And I thought I’d just got my next project 
Andy
I have GE smart fan switches and my handler doesn't look like yours. Is that something special to get the High/medium/low option?
The problem you are having is because Dale, like many devs in ST, is using a hybrid method that allows you to merge the child and parent apps into one "hybrid" app. You will need to split the app into 2 separate apps for it to work in HE.
@Shane_pcs
First delete the hybrid app you have installed.
Then install the parent app
then the child app.
See code below.

Virtual Thermostat for 3 Speed Ceiling Fan Control
Copyright 2016 SmartThings, Dale Coffing
This smartapp provides automatic control of Low, Medium, High speeds of a ceiling fan using
any temperature sensor with optional motion override.
It requires two hardware devices; any temperature sensor and a dimmer type smart fan controller
such as the GE 12730 or Leviton VRF01-1LX. Incorporates contributions from:
Eric Vitale (https://github.com/ericvitale/SmartThingsPublic/blob/master/smartapps/dcoffing/3-speed-ceiling-fan-thermostat.src/3-speed-ceiling-fan-thermostat.groovy)
Change Log
2017-04-11 Added 10.0 selection for Fan Differential Temp to mimic single speed control
2016-10-19 Ver2 Parent / Child app to allow for multiple use cases with a single install - @ericvitale
2016-06-30 added dynamic temperature display on temperature setpoint input text
2016-06-28 x.1 version update
added submitOnChange for motion so to skip minutes input next if no motion selected
changed order of inputs for better logic flow
added separate input page for Configuring Settings to reduce clutter on required inputs
change to other mode techinque to see if it will force a reevaluate of methods
renamed fanHiSpeed to fanSpeed for more generic use, added 0.0 on timer selection
changed motion detector minutes input only if motion selected submitOnChange
2016-06-03 modified the 3 second startup to 1 for low speed
2016-5-30 added dynamicPages for user guide, combined version data with aboutPage parameters which
gives a larger icon image then if used alone in paragraph mode.
2016-5-19 code clean up only
2016-5-17 fanDiffTemp input changed to use enum with preselected values to overcome range:"0.1..2.0" bug
2016-5-16 fixed typo with motion to motionSensor in hasBeenRecentMotion()
fixed IDE integration with ST by making another change to file name specifics.
2016-5-15 fixed fan differenial decimal point error by removing range: "1..99", removed all fanDimmer.setLevel(0)
added iconX3Url, reworded preferences, rename evaluate to tempCheck for clarity,
best practices to utilize initialize() method & replace motion with motionSensor,
2016-5-14 Fan temperature differential variable added, best practices to change sensor to tempSensor,
2016-5-13 best practices to replace ELSE IF for SWITCH statements on fan speeds, removed emergency temp control
2016-5-12 added new icons for 3SFC, colored text in 3SFC125x125.png and 3sfc250x250.png
2016-5-6 (e)minor changes to text, labels, for clarity, (^^^e)default to NO-Manual for thermostat mode
2016-5-5c clean code, added current ver section header, allow for multiple fan controllers,
replace icons to ceiling fan, modify name from Control to Thermostat
2016-5-5b @krlaframboise change to bypasses the temperatureHandler method and calls the tempCheck method
with the current temperature and setpoint setting
2016-5-5 autoMode added for manual override of auto control/*
2016-5-4b cleaned debug logs, removed heat-cool selection, removed multiple stages
2016-5-3 fixed error on not shutting down, huge shout out to my bro Stephen Coffing in the logic formation
I modified the SmartThngs original Virtual Thermostat code which is buggy. Known issues
-[Fixed] when SP is updated, temp control isn't evaluated immediately, an event must trigger like change in temp, motion
- if load is previously running when smartapp is loaded, it isn't evaluated immediately to turn off when SetPt>CurrTemp
- temperature control is not evaluated when making a mode change, have to wait for something to change like temp
Thanks to @krlaframboise, @MikeMaxwell for help in solving issues for a first time coder. @MichaelS for icon background

}Does compile and run now, however the app doesn't show up in the App List after I configure one. If I try to load it again I do see the previous child app on that page.
I had something similat happen when I first ported ABC over. I can add the code for that and post for you later.
What happens is that you end up configuring the child before completely creating the parent. If you want to test it out now...delete the app from your app list (not the code). Then add it back..but his time click on done before setting up any child apps. This way it initialized the parent completely. Now you can go back in and create the child.
What I did in ABC was force you to hit done the first time the app is loaded. Then when you reopen the app it provides the options to create new children. Just a few lines of code.
That worked perfectly. Thank you. I had that happen previously but I didnt think of it. Seems like you should always click done prior to installing any child apps.
This app works great for one of my fans. But how do I add another fan for another room? When I click Add Fan Automation, instead of creating another child, it just replaces the one I had defined previously.
I don't know coding well enough to allow more than one fan to be installed.
NVM. Found the issue. After pouring over code of other apps, I had to remove the singleInstance: true statement in the child's definitions.
I found this setting in the parent app, not child, and deleted it, but I still can get only one fan automation. Anything else special you had to do to get this to work?
The parent app still has singleInstance: true in it. But if you look at the child code in a few posts above, there is a singleInstance: true in it in the definition space. Right under the parent: section.
That is the one I deleted.
