Version: 1.4
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.
The Automation Process:
- When the sensor rises above the set value it turns the fan ON.
- When the sensor falls below the set value it turns the fan OFF.
- If you would like the opposite values then try this blueprint. â Temperature Control Exhaust Fan - Inverted
- You have the option to use the âFan Speed - Off Switch Optionâ. This is useful for turning OFF fans with different speeds.
- You have the option to use the âTrigger Sensor By-passâ. 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.
Note: If you turn the fan on manually and the automation runs it will turn the fan OFF automatically. It is recommended to use the âTrigger Sensor By-passâ option if you would like to keep the fan ON or OFF for extended time periods.

**The Automation Process:**
- When the sensor rises above the set value it turns the fan ON.
- When the sensor falls below the set value it turns the fan OFF.
- 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.
Note: If you turn the fan on manually and the automation runs it will turn the fan OFF automatically. It is recommended to use the "Trigger Sensor By-pass" option if you would like to keep the fan ON or OFF for extended time periods.
