Version: 1.2 :fire:

The most common automation used for a Temperature Control Exhaust Fan. It really can turn anything ON and OFF on a rising & falling numeric value :partying_face:

Need help? :eyes: See our FAQ: Click Here

:newspaper: The Automation Process:

  • When the sensor falls below the set value it turns the fan ON.
  • When the sensor rises above the set value it turns the fan OFF.
  • If you would like the opposite values then try this blueprint. 🌡 Temperature Control Exhaust Fan
  • You have the option to use the “Fan Speed - Off Switch Option”. This is useful for turning OFF fans with different speeds.
  • You have the option to use the “Trigger Sensor By-pass”. This allows you to add a switch to manually By-pass the trigger sensor so you can use the fan as normal by turning it ON and OFF manually.
  • You have the option to set a start time, an end time and select weekdays. This will only allow the automation to run between the time periods.
  • Safe guard built in for HA restart.

:rocket: CHANGELOG

  • Version: 1.2 - 21 Sep-23 - Update deprecated code.
  • Version: 1.1 - 10 July-23 - Added a 3 new option to the by-pass & a auto OFF option + more options with some bug fixes.
  • Version: 1.0 - 29 Jan-23 - Initial release

FAQ

Q: I don’t fully understand the “Fan Speed - Off Switch Option”, could you explain it to me?

A Sometimes you need to select a different entity to turn the fan OFF. This is normally used when having a fan that has different speeds and one of the speeds is OFF. You normally have to turn ON the switch to turn the fan OFF. If you have this scenario then select your OFF speed entity here. If you do not have this, then please leave it blank.

Q: How to use the “Trigger Sensor By-pass” without having a physical switch?

A: Go to Settings / Devices & Services / click on the “Helpers” tab / click “+ CREATE HELPER” and select “Toggle”. In the name put “Temp Exhaust Fan Sensor By-pass” and click save. Then go back into the automation and in the “Trigger Sensor By-pass” search for the name you created in this case “Temp Exhaust Fan Sensor By-pass” and click save. Now in a “Dashboard” click “Edit dashboard” then click “+ ADD CARD” click on “Button” or “Entities” in the entity field again search for the name you created in this case “Temp Exhaust Fan Sensor By-pass” and click save. Then click “DONE”. You now have a “Temp Exhaust Fan Sensor By-pass” switch to disable the Exhaust Fan.

Q: I would like to set a different value but the slider is not letting me?

A Just simply type the number value you would like in the field and click save. A red line will appear under the number you have entered but once you click save, exit the automation and go back into it the red line will not be there.

Hello, I want pretty same, but not exact this :). Can you help with blueprints for my needs (I think there are other people who want to :slight_smile: ).
I have 4 chanel switch (sonoff 4chpror3) and want control it by temp sensor (sonoff SNZB-02) my room (floor) temperature. If temp is under 22C its turn in 1 channel, and if above 22C then turn same channel off.
How it multiple for different rooms.

Switch is just switching on and of my accurator on underfloor heating conture.

@TomATom Hi Toomas,

This blueprint will do that but if you have 4 channels then you will need to create 4 automations, one for each room using the blueprint.

So go into blueprints and select this blueprint fill out everything for channel 1 and when saving it name it what you would like, example: “Underfloor Heating - Bedroom 1”. Then just do it again and select channel 2 and save it as “Underfloor Heating - Bedroom 2” and so on. Then when you click on the automations tab you will see 4 automations, one for each bedroom.

Work perfectly :slight_smile:) Thanks a lot
Can you advise is it possible to juse your bluprint :Temperature Control Exhaust Fan and Temperature Control Exhaust Fan - Inverted together (summer / winter time), to set some time (day and month) to sart one bluprint and stop at same time another? I want use my heatpump for cooling in summertimes to.

#6

Nice, no problem :+1:

You could but I would manually turn off my boiler and manually turn on my heat pump in summer time (and visa versa for winter). Last thing you need is your boiler turning on in the summer heating your floor up and finding out later (when you come home) it came on $$$$, and now your floor is hot… that takes a while to cool down. It would also be hard to pick a date to change over from heating to cooling.

EDIT: You could also create a summer and a winter by-pass to stop all your automations. Example if you created one by-pass for all your Underfloor Heating then put the same by-pass in every automation you just created. Now when you turn that ON it will stop all the Underfloor Heating automations.

New update 1.1

This is quite a big update :firecracker:. I am slowly going through my blueprint so they all look and feel the same :partying_face:

New Features :new:

  • Added “Fan” domain to fan switch.

  • Added enable / disable option to the “Fan Speed – Switch OFF Option”.

  • Added Fan domain to “Fan Speed – Switch OFF Option”.

  • Upgraded by-pass to have 3 options. You can now choose what you would like the fan to do when you turn the by-pass ON.

    1. Turn fan ON.
    2. Turn fan OFF.
    3. Keep the current fan state.

  • Added the ability to use a “By-pass Auto OFF Option”. This is used when you turn the by-pass ON and you would like the by-pass to automatically turn OFF in a set time delay. It can also be used as a timer to turn the fan ON and then OFF if you have chosen to use “Enable the By-pass - Turn fan ON”.

  • Added end of time trigger. The fan will turn OFF when end time crosses over and your “Rising Value” is over it’s setting.

  • Added some safe guards for HA restart.

  • Cleaned up some code.

Bugs Fixes :bug:

  • Start of time trigger.
  • Some other bugs.

New update 1.2

:warning: BLUEPRINT CODE UPDATE :exclamation:

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 “DEPRECATED” 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 “DEPRECATED” code from their system. :wink: :+1:
