README
Custom Template for checking the availability of an entity.
[](https://github.com/custom-components/hacs)
# 🧯 Availability-Template
The main reason for using this template is not because it's complicated, it's because availability is something you will be using over and over when you are dealing with sensors, so being able to repeat the same action over and over is better if there is 1 place in your project that the code exists.
Documentation for this Custom Template can be found at:
- The Description in the template itself.
- The github readme: https://github.com/SirGoodenough/Availability-Template/blob/master/README.md.
- Home Assistant Community Forum: https://community.home-assistant.io/t/availability-template/659955.
This requires HomeAssistant version 2023.11.0 or greater due to the use of the list test in the code.
# 🔩 Installation
Install this in HACS or download the `availability_template.jinja` from [this repository](https://github.com/SirGoodenough/Availability-Template) and place the files into your `config\custom_templates` directory.
[](https://my.home-assistant.io/redirect/hacs_repository/?owner=SirGoodenough&repository=Availability-Template&category=template)
#### If you cannot see templates in your HACS listing
You *may* need to enable 'experimental features' mode. To do this find the HACS section of the Home Assistant Integration page. Click on the '>' arrow to bring you to the custom integration page. Then click on configure, and select 'enable experimental features' check box. click submit, then float out and restart the HA server to make sure it takes. When you come back HACS will look slightly different, but the Templates section is now visible and you will be able to select it. At some point in time HACS will update and the new interface and options will be the only available interface.
#### Other help
Before you report a 'Bug', you need to make sure you have read the accompanying Descriptions on the templates and this README and have followed all the settings required here.
This is important because if these instructions are not followed, you will likely have a bad day and be forced to contact me for help. Not that I don't want to help, but personal interaction takes me a while to respond and is generally non-productive.
Another good thing to do before you ask for help is try testing what you have in the Developer Tools Template Tab in Home Assistant. There you can adjust this and that until you figure out the answer to your question yourself. [](https://my.home-assistant.io/redirect/developer_template/)

# Availability Test
## `avail([entity1, entity2, /])`
This expects a list of entities.
- The number of entities are counted.
- The number of entities that are NOT unknown, unavailable, empty, or none are counted.
- If the 2 counts are the same, true is returned, else false, defaults to false.
### REMEMBER!!
> This always returns text, so cast to bool on the other end to be certain of the result.
>
> Use of the - character in the return template ensures no unwanted spacing is pulled back with your answer.
### Examples
Generically, this can be dropped into many templates to be sure the result will render properly.
```jinja
availability: >-
{% from 'availability_template.jinja' import avail %}
{{- avail(['entity_1','entity_2']) | bool -}}
```
Here is a full example that uses this. It will give you percent sunshine estimate based on data from sun angle and cloud coverage if you have those integrations in your config. (Found the state statement somewhere a while ago, sorry there is no attribution. I use it in my personal config.)
```yaml
- template:
- sensor:
- name: "sunlight_pct"
unique_id: 9a7586c0-0947-4b41-97e0-c0d2150bd0bb
unit_of_measurement: "%"
state: >-
{%- set elevation = state_attr('sun.sun','elevation') | float %}
{%- set cloud_coverage = states('sensor.openweathermap_cloud_coverage') | float %}
{%- set cloud_factor = (1 - (0.75 * ( cloud_coverage / 100) ** 3 )) %}
{%- set min_elevation = -6 %}
{%- set max_elevation = 60 %}
{%- set adjusted_elevation = elevation - min_elevation %}
{%- set adjusted_elevation = [adjusted_elevation,0] | max %}
{%- set adjusted_elevation = [adjusted_elevation,max_elevation - min_elevation] | min %}
{%- set adjusted_elevation = adjusted_elevation / (max_elevation - min_elevation) %}
{%- set adjusted_elevation = adjusted_elevation %}
{%- set adjusted_elevation = adjusted_elevation * 100 %}
{%- set brightness = adjusted_elevation * cloud_factor %}
{{ brightness | round }}
availability: >-
{% from 'availability_template.jinja' import avail %}
{{- avail(['sun.sun','sensor.openweathermap_cloud_coverage']) | bool -}}
icon: mdi:sun-angle
attributes:
friendly_name: "Sunlight Percentage"
```

⚠️ **DANGER OF ELECTROCUTION** ⚠️
If your device connects to mains electricity (AC power) there is danger of electrocution if not installed properly. If you don't know how to install it, please call an electrician (***Beware:*** certain countries prohibit installation without a licensed electrician present). Remember: **SAFETY FIRST**. It is not worth the risk to yourself, your family and your home if you don't know exactly what you are doing. Never tinker or try to flash a device using the serial programming interface while it is connected to MAINS ELECTRICITY (AC power).
