There is no need for a triggered template sensor. This is redundant:
Templates are already monitored for state changes of the included sensors.
This will do exactly the same thing:
template:
- sensor:
- name: Weight Eq and Above Threshold
unique_id: f700e52a-1304-4d47-8bea-5b2c8f4049fe
unit_of_measurement: kg
device_class: weight
state: >
{% set weight = states('sensor.bluetooth_proxy_miscale_weight') | float %}
{{ weight if weight >= 80 else this.state }}
availability: "{{ has_value('sensor.bluetooth_proxy_miscale_weight') }}"
- name: Weight Below Threshold
unique_id: 42e1e5c9-1476-4e8d-9e8d-9071021ebb4b
unit_of_measurement: kg
device_class: weight
state: >
{% set weight = states('sensor.bluetooth_proxy_miscale_weight') | float %}
{{ weight if weight < 80 else this.state }}
availability: "{{ has_value('sensor.bluetooth_proxy_miscale_weight') }}"
