I believe the source of this Byzantine wonder is this post:
I recall skimming through its code and wondering if its complexity was due to the possibility that monitoring battery status is far more difficult than I ever imagined. However I lost interest before I was convinced this elaborate mechanism is truly required to simply report “Battery, Aziz!” 
Added the changes to this branch here:
Interestingly, in my ‘Developer Tools’ -> ‘Template’, I also cannot get it to work:
Wow, I didn’t think that it was still this popular.
It’s just a typo. The code refers to ns.entities when it ought to be using ns.results.
Seems to be ns.entites
FWIW, there are other solutions posted in this forum that can report low battery level with far less complexity. If you are interested, just search for ‘battery level’.
Either way, it’s referring to an undefined variable. It should be ns.results.
You’re right, I can’t deny that there are better and certainly easier ways of doing this.
I’m just trying to get this to work.
Can you elaborate on the ns.results?
When I correct both entries to ns.results I get the same error.
Sorry, I have no interest in continuing to breathe life into this thing. It appears even its author has lost interest in maintaining it.
I would suggest starting fresh or enhancing one of the other battery level solutions. Good luck!
Alright, I just wanted to know what you meant.
Thanks anyway.
just change all ns.entities to ns.results…
{%- set show_unavailable = false %}
{%- set high = 30 %}
{%- set low = 0 %}
{%- set ns = namespace(results=[]) %}
{%- for s in expand('group.battery_status') %}
{%- if s.state in ['unknown', 'unavailable'] and show_unavailable and not (s.attributes.battery_alert_disabled or s.attributes.restored) %}
{%- set ns.results = ns.results + [ s.name ~ ' ' ~ s.state ] %}
{%- else %}
{%- if s.state.lower() in ['low', 'medium', 'high'] %}
{%- if s.state.lower() == 'low' %}
{%- set ns.results = ns.results + [ s.name ~ ' ' ~ s.state ] %}
{%- endif %}
{%- elif low < s.state | float < high %}
{%- set ns.results = ns.results + [ s.name ~ ' ' ~ s.state ] %}
{%- endif %}
{%- endif %}
{%- endfor %}
{{ ns.results | join(', ') }}
I just plopped your code into my dev tools template editor and got my expected result which agrees with my working installation of battery_alert:
@dbrunt yeah sorry man, I’m not entirely sure either, but slow progress is still progress.
@petro Thanks for that update, I’ve been messing around with it, and refined it a little to work:
{%- set show_unavailable = ( states.input_boolean.show_unavailable_batteries.state == 'on' ) %}
{%- set high = states('input_number.battery_alert_threshold_max') | float %}
{%- set low = states('input_number.battery_alert_threshold_min') | float %}
{%- set ns = namespace(results=[]) %}
{%- for s in expand('group.battery_status') %}
{%- if s.state in ['unknown', 'unavailable'] and show_unavailable and not (s.attributes.battery_alert_disabled or s.attributes.restored) %}
{%- set ns.results = ns.results + [ s.name ~ ':' ~ s.state ] %}
{%- else %}
{%- if s.state.lower() in ['low', 'medium', 'high'] %}
{%- if s.state.lower() == 'low' %}
{%- set ns.results = ns.results + [ s.name ~ ':' ~ s.state ] %}
{%- endif %}
{%- elif low < s.state | float < high %}
{{ s.name }} ({{ s.state }})
{%- endif %}
{%- endif %}
{%- endfor %}
But I seem to have run into a different issue, and after some messing around I can’t seem to understand why.
The code above works in the template editor, and I can see side-by-side with the old version:
{% macro battery_level() %}
{% for entity_id in states.group.battery_status.attributes.entity_id if (
not (
is_state_attr(entity_id, 'battery_alert_disabled', true)
or is_state_attr(entity_id, 'restored', true)
)
and states(entity_id) is not none
and (
(
(
states(entity_id) is number
or states(entity_id) | length == states(entity_id)| int | string | length
or states(entity_id) | length == states(entity_id)| float | string | length
)
and states(entity_id) | int < states.input_number.battery_alert_threshold_max.state | int
and states(entity_id) | int > states.input_number.battery_alert_threshold_min.state | int
)
or states(entity_id) | lower == 'low'
or states(entity_id) | lower == 'unknown'
or states(entity_id) | lower == 'unavailable'
)
) -%}
{{ state_attr(entity_id, "friendly_name") }} ({{ states(entity_id) }})
{% endfor -%}
{% endmacro %}
{{ battery_level() }}
The trouble is, I cannot get it to fire as a persistent notification when I run automation.battery_persistent_notification.
I can see the event and automation trigger, and if I enter a static string, or the old code, the notification shows up.
Is this a type error or something that’s just not showing up?
Any idea why this would be?
Your refinement completely makes the entire logic break. Now you’re only reporting the values if they are between the low and high thresholds and your outputing them in the loop. It won’t include ANY of the other logic.
I tried your code as-is exactly how you posted it above many times, and it doesn’t post any result, outside of in the template editor.
I tried modifying it, and it still doesn’t report anything, when not run within the template editor.
I ask that maybe if you could try it and see.
I’m pretty sure I’m not being silly with this.
I’ve committed your code to this branch as-is, can you take a look?
Can you try the battery_alert.yaml?
Because its really not working as it should.
It works in the template editor, but it doesn’t work otherwise.
I’ve tested other methods, and plain strings and other scripts and they all work.
The issue is that is doesn’t output anything when it is run as automation.battery_persistent_notification
I am using battery_alert.yaml:

## Install Instructions
################################################################
##
## 1. Enable MQTT using your preferred MQTT broker
## https://home-assistant.io/components/mqtt/
##
## 2. Enable MQTT Discovery by adding `discovery: true` and
## `discovery_prefix: homeassistant` under the `mqtt:` section
## of your configuration.yaml
##
## mqtt:
## discovery: true
## discovery_prefix: homeassistant
##
## 3. Save this file as CONFIGDIR/packages/battery_alert.yaml
##
## 4. Add `packages: !include_dir_named packages` under the
## `homeassistant:` section of your configuration.yaml
##
## homeassistant:
## packages: !include_dir_named packages
##
## 5. Restart Home Assistant
##
## 6. Adjust Min Alert Threshold slider to the minimum battery
## level to alert on. Note: the input slider requires the
## recorder component to keep it's state through restarts.
## If recorder is not enabled, the threshold can be set by
## un-remarking `initial` and setting the preferred default.
##
## 7. Adjust Max Alert Threshold slider to the maximum battery
## level to alert on. Note: the input slider requires the
## recorder component to keep it's state through restarts.
## If recorder is not enabled, the threshold can be set by
## un-remarking `initial` and setting the preferred default.
##
## 8. Setup notifications by entering the notifier name in the `Notifier Name` input text box.
## E.g. `notify.slack`. If no value is entered, it defaults to `notify.notify`.
##
## 9. Set the notifier format by selecting either `Default` or `Slack. Note: most notifiers
## are compatible with the `Default` format.
##
## 10. To disable alerts for a specific entity, use customize to
## set `battery_alert_disabled` to `true`
##
## homeassistant:
## customize:
## sensor.sensor_name_to_ignore_battery:
## battery_alert_disabled: true
##
## 11. To disable creating a sensor from battery attributes for a specific entity, use customize to
## set `battery_sensor_creation_disabled` to `true`
##
## homeassistant:
## customize:
## sensor.sensor_with_battery_attibute:
## battery_sensor_creation_disabled: true
##
## 12. If a battery attribute requires a template to convert it into a usable percent, use customize
## to add `battery_template` with the necessary template. The template result must be a number
## that represents a percentage.
##
## This example will create a battery sensor with the value of battery_level * 2
##
## homeassistant:
## customize:
## sensor.sensor_with_battery_attibute_template:
## battery_template: "{{ value_json.value | int * 2 }}"
##
## 13. If a battery attribute requires a template to convert it into a string, use customize to add
## `battery_template_string` with the necessary template. The template result must be a string.
## For example, "Low" will trigger low battery notification).
##
## This example will create a battery sensor that contains "Low" if battery_level
## is less than 2
##
## homeassistant:
## customize:
## sensor.sensor_with_battery_attibute_template:
## battery_template_string: >-
## {%- if value_json.value < 2 -%}
## Low
## {%- else -%}
## Full
## {%- endif -%}
