What advantage does the package: ‘battery_alert’ have in the customize section? Isn’t the package established as a top level item? For example:
packages:
battery_alert:
homeassistant:
customize:
group.battery_alert:
friendly_name: "Battery Alert"
icon: mdi:steam
sensor.battery_status:
friendly_name: "Battery Status"
icon: mdi:battery
The customize section sets the friendly name and icons so you don’t have to do it outside of the package.
Yeah, I use it extensively but I’m not sure why the package provided above uses the package: battery_alert within the customize section.
I’ve been searching for ages to try and work out what the node_anchors bit is all about and come up completely blank. Only the devs seem to use them, so I don’t know whether it helps for debugging something or other, but there doesn’t seem to be any advantage.
Example:
homeassistant:
customize:
package.node_anchors:
customize: &customize
package: 'battery_alert'
expose: &expose
<<: *customize
haaska_hidden: false
homebridge_hidden: false
group.battery_alert:
<<: *customize
friendly_name: "Battery Alert"
icon: mdi:steam
automation.battery_alert:
<<: *customize
friendly_name: "Battery Alert"
automation.battery_alert_clear:
<<: *customize
friendly_name: "Battery Alert Clear"
homeassistant:
customize:
group.battery_alert:
friendly_name: "Battery Alert"
icon: mdi:steam
automation.battery_alert:
friendly_name: "Battery Alert"
automation.battery_alert_clear:
friendly_name: "Battery Alert Clear"
… And the latter is 10 lines fewer code.
Anybody enlighten us?
(also, from a code reduction point of view, the group name and automation names could be set as part of their declaration, which would reduce the customize section to only 2 lines (to set the icon for the group)
I don’t completely understand the differences between the 2 formats either. I guess it’s a matter of personal preference or perhaps a more complex package would make the reasons more obvious…
Would love a definitive answer, if nothing else to satisfy my curiosity 
@CCOSTAN , @dale3h I’m sure I’ve seen you guys use the node_anchors dooberies in your packages?
Scratch that… I did create the package version, though with the earlier code (haven’t tried your latest) and triggering manually does work sending to my notify.android_alerts and it shows the “Low Battery Levels [Dismiss]” card without any sensors.

Triggering the automation manually will send an empty notification because it skips the condition that prevents it. You shouldn’t get the notification if it’s triggered by the automation’s trigger.
I’ve done some refactoring of the package to add some new features and fix a couple of issues. The biggest improvement is that it automatically creates a separate sensor for each entity that has an attribute named battery_level or battery numeric. This new feature leverages MQTT Discovery to create the battery sensors.
I also split out the Slack and persistent notification into 2 automations. the Slack one runs twice daily and the persistent notification one runs every 15 minutes. For anyone that doesn’t use Slack or uses some other notification component, it should be easier to disable and/or modify.
It’s quite a big change and I haven’t done extensive testing, so there might be issues that I haven’t encountered yet. The biggest issue that I don’t like is the icon isn’t based on battery level, and I don’t want to create templates just to set the icons. I think adding the ability to set the icon via MQTT Discovery would be the best option, but that’s not available today.
This version of the package now requires MQTT and MQTT Discovery to be enabled. I’ve hard coded the prefix to homeassistant in the package, so you may need to change that if you want to use something different. To enable MQTT DIscovery, add discovery: true and discovery_prefix: homeassistant under the mqtt: section of your configuration.yaml.
mqtt:
discovery: true
discovery_prefix: homeassistant
Finally, here is the new battery_alert.yaml package.

Hi Notorious
Your code is really nice! I’ve been looking for something like this for a long time, been using separate packages and adding each sensor manually.
One issue I have is that some of my sensors are reporting “unknown” battery state and I can’t figure out why.
I copied your code without any changes except for the slack notification.
If I check the first “unknown” entry “3D Temp Battery” here’s what my dev-state page shows this
First I saw was that 3d_fukt reports 37% but the actual battery level of “sensor.humidity_158…” is 35%
And the temp sensor reporting “unknown” does in fact show a battery level of 35% in dev-state.
Any good idéas on why this is happening? 
The issue is your battery levels are floats and the automation didn’t account for that. Please try this updated version.
For others using this package, I’ve added another automation that creates sensors for entities that have a battery attribute such as Owntracks.

Worked like a charm! Thanks alot Notorious! It was nice to see some advanced templating as well, gave me a lot of idéas and “how-to’s” for other functions for my home
Hi @NotoriousBDG - just installed this, thanks for the work
Please note there is a typo in your installation comment. It should read
## 3. Save this file as CONFIGDIR/packages/battery_alert.yaml
ie plural packageS
Thanks. Fixed…
Workd like a charm. Thank you so much. The earlier one also works like a charm.
I implemented the last version, MQTT, and all smiles.
Just one thing though. The code reports my phone, and a Fibaro water sensor which has battery and AC. For some reason the battery level is constant 4.
Code that could ignore some selected sensors would be nice.
@Tomahawk, that’s an awesome idea. I’ve updated the package to add that feature. To disable alerts for a specific entities, set battery_alert_disabled: true in customize for each sensor you wish to ignore.
homeassistant:
customize:
sensor.sensor_name_to_ignore_battery:
battery_alert_disabled: true
I’ve updated the package to move the min and max alert thresholds to input_number entities, which makes them configurable via the UI. These values must initially be set via the UI to your desired alert thresholds for alerts to work correctly. Note: A working recorder component is recommended to persist the input_number states through restarts. However, an initial value can be forced by un-remarking the initial lines in the package yaml if you don’t have the recorder component configured.
Lastly, I’ve adjusted the code to make it much easier to read.

## 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. To disable alerts for a specific entity, use customize to
## set `battery_alert_disabled` to `true`
##

Excellente!
People like you making stuff like this, gives N00bs like me the ability to take part in the fun.
This is good stuff. I appreciated the hard work from everyone here.
One question. I added this and the sensors and automations loaded correctly. Problem I have is that it doesn’t show up in my front end. I have a heavily modified groups.yaml with only certain groups set to view: yes. I tried adding group.battery_alert to one of my tabs set for view: yes, but it never shows up. I am going to try and just manually dump the entities into my groups.yaml, but out of curiosity, what am I doing wrong with the packages file to make it show up in front end?
Thanks.
Are you reloading groups or automations via the UI? If so, that’s the reason why they’re disappearing. Unfortunately, that’s a known issue when using packages. Your best option is to restart Home Assistant after changing groups and automations.
