I have a few leak sensors throughout the house and plan to get some more. Instead of setting up an alert for each individual sensor I wanted to combine them all into a single binary sensor and use that to trigger the alert.
This is what I have:
- platform: template
sensors:
h2o:
friendly_name: 'Water'
sensor_class: 'moisture'
value_template: >-
{% if is_state("binary_sensor.water_heater_liquid_detected", "on")
or is_state("binary_sensor.under_kitchen_sink_liquid_detected", "on")
or is_state("binary_sensor.guest_bathroom_liquid_detected", "on") %}
On
{% else %}
Off
{% endif %}
entity_id:
- binary_sensor.under_kitchen_sink_liquid_detected
- binary_sensor.guest_bathroom_liquid_detected
- binary_sensor.water_heater_liquid_detected
I get no errors at all, the sensor is created, and when I put the value_template part into the template into the Jinja2 template jawn it appears like it should work. If I manually change one of the sensors to on, it gives me an output of βonβ; otherwise it shows as βoffβ.
However, the sensor itself never changes. Am I missing something here?
