Hi,
I try to make my icon_template works, it works in devtool template preview tab but when I put the code in configuration.yaml it throws an error
Invalid config for [sensor]: [icon_template] is an invalid option for [sensor]. Check: sensor->icon_template. (See /config/configuration.yaml, line 151).
I tried many things but do not figure out why it does not work.
I tried to set a variable to store sensor value to make it more readable but don’t knoww if we can set vars in icon_template.
I tried to format yaml with vscode yaml extension but the same.
mqtt:
sensor:
# **** MQTT Shelly Flood Battery ****
- name: "MQTTT Shelly Flood Battery"
state_topic: "shellies/shellyflood-987654321edcba/sensor/battery"
unit_of_measurement: "%"
device_class: battery
icon_template: >
{% if is_number(states('sensor.shelly_flood_987654321edcba_battery')) and states('sensor.shelly_flood_987654321edcba_battery') | float == 100 %}
mdi:battery
{% elif states('sensor.shelly_flood_987654321edcba_battery')|float <= 15 %}
mdi:battery-outline
{% else %}
mdi:battery-{{(states('sensor.shelly_flood_987654321edcba_battery')|float / 10)|round*10}}
{% endif %}
