The code would be great, thanks so much!
No problem 
Below are 2 sensors. One for a individual person and one for the zone. You will need to decide what suits you. If you would like to track multiple persons then you could create all your person sensors and then group them with a helper. The zone one is for any device in a zone you are tracking. You then would enter this code into your āconfiguration.yamlā file and restart home assistant. You will then have the new sensor you can enter into the by-pass.
Things you can change to your liking are;
- ceiling_fan_zone_person_blacky_sensor - (The name must be unique and be in lower case and if you would like a space then it must be ā_ā. This is the entity ID of your sensor)
- Ceiling Fan Zone - Blacky Home Sensor
- presence
- mdi:map-marker-account-outline
- ceiling_fan_zone_sensor - (The name must be unique and be in lower case and if you would like a space then it must be ā_ā. This is the entity ID of your sensor)
- Ceiling Fan Zone - Home Sensor
Things you must change (entity name) or check the zone you have
- device_tracker.blacky_iphone
- āhomeā - you may have a different zone name other than āhomeā
- zone.home
This is for a person.
binary_sensor:
- platform: template
sensors:
ceiling_fan_zone_person_blacky_sensor:
friendly_name: "Ceiling Fan Zone - Blacky Home Sensor"
device_class: presence
icon_template: mdi:map-marker-account-outline
value_template: >-
{% if states('device_tracker.blacky_iphone', 'home') %}
off
{% else %}
on
{% endif %}
This is for a zone.
binary_sensor:
- platform: template
sensors:
ceiling_fan_zone_sensor:
friendly_name: "Ceiling Fan Zone - Home Sensor"
device_class: presence
icon_template: mdi:map-marker-account-outline
value_template: >-
{% if states('zone.home')|float > 0 %}
off
{% else %}
on
{% endif %}
You could have both, so if a bedroom for āblackyā has a ceiling fan and when blacky is home the fan will work. You could have another bedroom that is for a different person so you would add another sensor in for that person. But you could have ceiling fans in kitchen then you could use zone or a group helper with all your person sensors selected. You would then use the correct sensor for the automation.
This is using both sensors together. NOTE: We only need one ābinary_sensor:ā header.
binary_sensor:
- platform: template
sensors:
ceiling_fan_zone_person_blacky_sensor:
friendly_name: "Ceiling Fan Zone - Blacky Home Sensor"
device_class: presence
icon_template: mdi:map-marker-account-outline
value_template: >-
{% if states('device_tracker.blacky_iphone', 'home') %}
off
{% else %}
on
{% endif %}
- platform: template
sensors:
ceiling_fan_zone_sensor:
friendly_name: "Ceiling Fan Zone - Home Sensor"
device_class: presence
icon_template: mdi:map-marker-account-outline
value_template: >-
{% if states('zone.home')|float > 0 %}
off
{% else %}
on
{% endif %}
Hope this helps.

BLUEPRINT CODE UPDATE 
Just a heads up if your still on a old HA version before you update.
From time to time Home Assistant update their code structure and the old code will become āDEPRECATEDā stopping / breaking automations from working. It effected this blueprint about 4 to 6 months ago. I wanted to wait some time so everyone had a chance to update their HA version before updating the code as older HA versions can not run the new code. This blueprint has now been updated so it will still operate once HA remove the āDEPRECATEDā code from their system.

How do I set it that when the FAN goes on when passing a valueā¦ then normally it should go off when below a value. Sometimes it takes too long and would like it to turn off after 45min if it didnāt get below that value.
Good suggestion, I will look at it tonight and add maximum run time option. Stay tuned for the update.

New Features 
- Added āMaximum Run Time Option". This allows you to set a maximum run time for the fan if the falling value is not achieved.
- Added āGlobal Conditionsā. You can now set any condition you like.

It seems not to be workingā¦ settings are the same as before, only set maximum runtime to 60min.
Hi Kim
Could you please provide us your YAML of the automation? This YAML code are the settings you have selected in the automation so I can help. To do this go into your automation, top right 3 dots, Edit in YAML, copy all the code, come back to the forum and in your reply at the top tool bar click on ā</>ā and paste code in there.

Thanks Kim, found a bug, it is fixed and updating now. Let us know if it is working.

Bugs Fixes 
- Fix a bug if no global condition was set the automation would not run.

Hi - this seems to be exactly what iāve been after and as similar posts have suggested I am using it to trigger heating on/off. Thankyou!! 
I do seem to be having issue after my initial testing. If I manually run the blueprint it works as expected.
How frequently does it run, or pull data before a decision is made? Or do I need to something else with this? As it does not yet seem to be āautomatedā For info I have enabled time options and during testing they are within the range.
Firstly welcome to the community.

Many thanks for the welcome and reply. It is appreciated. As requested please see YAML code below. Hopefully I have just missed something silly(?)

No problem, good to know.
I will move this to the inverted blueprint to stop confusion for others reading this.
I have the same problem - I would like to run a script rather than operate a switch but only switch entities show up. HA version up to date.
Iāve tried editing the input code under domain to add ā-scriptā but that doesnāt seem to work - and I have to admit I have no idea what I an doing.
Any help?
I will PM you.

Hi Blacky.
I was wondering if you would consider adding the option that if a fan entity is selected, allow setting the fan speed and oscillation.
And thanks, I love your automations.
Thanks for you idea, I will add it to the list.
Your welcome.
A really nice option would be to add a time delay to the Trigger Sensor. The Temperature would have to be above Rising Value for X seconds. The same could be added to the Falling value. Also the ability to add scripts to the ran. I would like to send a notification when the fan turns on.
Thanks,
