Exactly! Iām thinking like you set the desired temperature on your AC unit with your remote. Sometimes you want a bit warmer and sometimes a bit cooler.
The min/max value would be set via the offset. Those youād just have to set once as the ātemperature curveā would then move up and down based on the set temperature.
Sir_Goodenough has a working input number in his BP if that would help
Would you be able to add to the blueprint an option to invert the blocking entity so that it would work with an entity that is off. My use case is a whole house fan that I want to run, but only when the window is open, which in this case it goes from an off state to on state.
Also it would be nice to have a separate enabling entity you can chose. Idea being I could install a remote switch that starts of the automation, otherwise the automation is disabled.
If youāre not aware a Blueprint can be converted to a regular Automation, then you could make all your customisations.
Hi @adamalli7, sorry for my late reply and thanks for your interest and ideas. Regarding your request to add an option to invert the blocking entity, I think the cost for implementing this in terms of the logic needed and the added complexity, proabably means I wonāt add this feature. A much easier way would be to create your own template sensor that inverts the state of your entity. Hereās an example of how to to that:
/config/configuration.yaml.configuration.yaml file, add the following lines to define your template sensor. Replace sensor.your_entity with the actual entity ID you want to invert.template:
- sensor:
- name: "Inverted Entity State"
state: >
{% if is_state('sensor.your_entity', 'on') %}
off
{% else %}
on
{% endif %}
availability: >
{{ states('sensor.your_entity') not in ['unknown', 'unavailable'] }}
Hope this helps!
I just changed the blueprint to do what I needed it to do. Simple as changing the entity value from āonā to āoffā
No worries, I know just how it is 
Hey,
I really like your blueprint the only thing that is missing is a maximum percentage change. I got some wild jumps on my air conditioning fan.
Could you implant this value as well?
Thanks!
Haha interesting! Was that caused by a large jump in temperature though? Whatās your thoughts on what should happen in this case? Eg: should the blueprint set the fan to the maximum allowed step change in fan speed and then continue to step it up until it eventually reached the required fan speed for the current temperature?
@Creepe95 ok Iāve added a maximum percentage change slider. Give it a go and let me know how it goes 
Update the blueprint by re-importing it. It is backwards compatible, so your old settings will be preseved if you have any automations that are already using this blueprint.
Notes on this change:
To ensure the set_fan_speed value never increases or decreases by more than a desired threshold, you can set a max_change which is a threshold value set for the difference betwen the current fan_speed and the calculated set_fan_speed. If the difference exceeds max_change, the set_fan_speed will be adjusted to fan_speed + max_change (for the positive direction) or fan_speed - max_change (for the negative direction) as necessary.
IMPORTANT!
Because the automation is triggered only when the temperature sensor changes or when the fan is turned on, if you have set a small max_change and the time between temperature changes is large, the time it takes for the fan to get the set_fan_speed could be large.
āedit-- nvm, I think the script below works.
Awesome blueprint!
Iāve tried to add the option to select another temperature sensor for the off_temp variable, which also influences the min_temp with an additional selector. But the fan speed doesnāt seem to change. Do you have any tips/remarks? Cheers.

Is there a change to Integration the climate entity directly?
Currently i need to create a extra Fan Sensor for that
