blueprint:
name: Low battery level detection & notification for all battery sensors
description: Regularly test all sensors with 'battery' device-class for crossing
a certain battery level threshold and if so execute an action.
domain: automation
input:
threshold:
name: Battery warning level threshold
description: Battery sensors below threshold are assumed to be low-battery (as
well as binary battery sensors with value 'on').
default: 20
selector:
number:
min: 5.0
max: 100.0
unit_of_measurement: '%'
mode: slider
step: 5.0
time:
name: Time to test on
description: Test is run at configured time
default: '10:00:00'
selector:
time: {}
day:
name: Weekday to test on
description: 'Test is run at configured time either everyday (0) or on a given
weekday (1: Monday ... 7: Sunday)'
default: 0
selector:
number:
min: 0.0
max: 7.0
mode: slider
step: 1.0
exclude:
name: Excluded Sensors
description: Battery sensors (e.g. smartphone) to exclude from detection. Only
entities are supported, devices must be expanded!
default:
entity_id: []
selector:
target:
entity:
device_class: battery
actions:
name: Actions
description: Notifications or similar to be run. {{sensors}} is replaced with
the names of sensors being low on battery.
