[Reinqusito]

Hi,
I need to get the count of the item with power < 10%.
I able to get the list of the power value (of this 4 entity zigbee group) but not the number of then above a value (f.i 10%)
Thanks

Try pasting this into your Template Editor-

{% set x = [20, 30, 50] %}
{{ x | select('lt', 50)| map('int') | list }}

lt stands for less than, if you want greater than, use gt

Thanks you two all!
Last question… how to get name of device in the list (and not the value of battery)?

This gets the value

{{ expand('group.all_zigbee_power') | map(attribute='state') | map('float') | select('lessthan', 10) | list }}

Thanks.

Try this-
{{ expand('group.all_zigbee_power') | rejectattr('state', 'eq', '100') | selectattr('state', 'lt', '10') | map(attribute='name') | list | join(', ') }}

Edit: incorrect suggestion. See Petro’s explanation.

That won’t work with state because it’s a string. 9 will be greater than 10, but 09 won’t.

The only way this can be done using the state is with namespace

{% set ns = namespace(entities = []) %}
{% for s in expand('group.all_zigbee_power') %}
  {% if s.state | float > 10 %}
    {% set ns.entities = ns.entities + [ s ] %}
  {% endif %}
{% endfor %}
{{ ns.entities | map(attribute='name') | list | join(', ') }}
