Hey everyone! I wanted to share my recent success in setting up a template sensor to manage multiple conditions for my garden irrigation system. This setup has been a game-changer for automating my watering routine without any hiccups. Let me walk you through how I did it!
The Goal:
I wanted to automate my rainwater pump and valves to irrigate my garden. The automation needed to consider several factors:
- Whether manual irrigation was enabled (
input_boolean.bewasserung_ein) - Whether it was not raining (
sensor.wetter_sensor_rain) - Whether the weather condition didn’t include ‘Regen’ (German for rain)
- Whether the season was either spring or summer (
sensor.season)
The Solution:
I decided to create a template sensor to combine all these conditions into one. This way, I could use this single sensor as a condition in my automations instead of having multiple nested conditions. Here’s how I set it up:
yaml
sensor:
- platform: template
sensors:
irrigation_condition:
value_template: >-
{{
is_state(“input_boolean.bewasserung_ein”, “on”) and
is_state(“sensor.wetter_sensor_rain”, “not raining”) and
not “Regen” in state_attr(“sensor.wetter_sensor_condition”, “state”) and
(is_state(“sensor.season”, “spring”) or is_state(“sensor.season”, “summer”))
}}
friendly_name: Irrigation Condition

How It Works:
- The template sensor evaluates all the conditions in a single place.
- If all conditions are met, the sensor returns
true, allowing the irrigation automation to proceed. - This setup simplifies my automations and reduces the chance of errors.
Benefits:
- Simplicity: Instead of nesting multiple conditions in each automation, I have a single point of truth.
- Maintainability: Updating conditions is easier since everything is in one place.
- Reduced Errors: Fewer moving parts mean fewer potential points of failure.
Final Thoughts:
This approach has been incredibly effective for my setup. I no longer worry about missing a condition or having nested logic errors. If you’re dealing with multiple conditions in your automations, I highly recommend exploring template sensors!
Happy automating!
