I recently dove into setting up a humidity-based automation system in my home, aiming to automate my bathroom fan based on humidity levels. It’s been quite the learning curve, but I’m thrilled with the progress I’ve made so far! Let me share my journey and some tips for anyone looking to achieve similar results.Initially, I wanted to create a simple setup where the fan would turn on when humidity exceeded 55% and switch off once it dropped below that threshold. Sounds straightforward, right? However, I encountered some challenges with the initial template logic. After some research and trial and error, I figured out that the key was to ensure the template correctly evaluated the sensor readings and triggered the appropriate actions.One thing I learned is the importance of precise condition settings. I realized that using float to convert the sensor readings was crucial for accurate comparisons. Additionally, organizing the automation into clear triggers and actions made the setup more manageable and less prone to errors.Here’s a simplified version of what worked for me:yamltrigger: - platform: template value_template: >- {% if state(‘sensor.main_bathroom_humidity’) | float > 55 %}true{% endif %} id: Above 55% Humidity - platform: template value_template: >- {% if state(‘sensor.main_bathroom_humidity’) | float < 55 %}true{% endif %} id: Below 55% Humidityaction: - choose: - conditions: - condition: trigger id: Above 55% Humidity sequence: - service: switch.turn_on data: {} target: entity_id: switch.main_bathroom_fan - conditions: - condition: trigger id: Below 55% Humidity sequence: - service: switch.turn_off data: {} target: entity_id: switch.main_bathroom_fanThis setup ensures that the fan activates when humidity rises above 55% and deactivates once it falls below, maintaining a comfortable environment without unnecessary operation.Reflecting on this experience, I’ve learned that patience and thorough testing are essential when working with templates and automations. It’s also been heartwarming to see the supportive community here, as their insights and advice have been invaluable. If anyone has tips or alternative approaches, I’d love to hear them!In the end, this project has not only improved my home’s comfort but also deepened my understanding of Home Assistant’s capabilities. It’s a rewarding feeling to see everything come together seamlessly. Thanks to everyone who contributes to this amazing platform and community!
