@pmd5700 - The code you are referring to does not exist in the most current version. Where are you copying the code from?

@jazzyisj I'm using this to trigger my automation:

binary_sensor:
  - platform: template
    sensors:
     unavailable_entities_alert:
        delay_on:
          seconds: 60 # delay before activating alert
        value_template: "{{ states('sensor.unavailable_entities')|int > 0 }}"

@pmd5700

That is not part of the package in this gist. That does look suspiciously like some template sensors I have in my personal config though..lol.
Anyway yes, you can just add a default value for int there. That should only happen on startup or when you're reloading templates.

value_template: "{{ states('sensor.unavailable_entities')|int(0) > 0 }}"

I use alerts for my notifications instead of an automation which is why I had to create the binary sensors in addition to the unavailable entities sensor. You could just use a numeric_state trigger if you're using an automation, you don't need the binary sensor template.

trigger:
 - platform: numeric_state
   entity_id: sensor.unavailable_entities
   above: 0

As for the template loop warnings - I'm not seeing them anymore again.
What is happening when you see that warning in your logs? Startup? Reloading templates?

@jazzyisj Thanks! I think I misread Bytelink5616's comment above. I was only getting the errors I posted above about the Int. I added the (0) and they seem to have gone away.

It should look familiar, I think you help me set it up ~a year ago lol. I tried the numeric state trigger, but I wanted to put a delay in the binary sensor so it didn't trigger all the time.

@pmd5700 Too funny..lol

This will give you your delay. Also if you're using the most current version you can increase the ignore_sec value to accomplish pretty much the same thing.

trigger:
 - platform: numeric_state
   entity_id: sensor.unavailable_entities
   above: 0
   for: 60

The Unavailable Entities Sensor has been moved to it's own package.

@massive

I have a similar issue as some others: I have a few devices that expose multiple sensors. I thought I could extend the sensor in a way that it would allow excluding sensors using regular expression. However, it seems that there is no elegant way to do that with HA and Jinja:

This feature is now available via the search test. The README in the new repository explains how to utilize it. I remembered your comment because it was the basis for my first failed attempt at accomplishing it with custom attributes so I thought I'd point it out to you.

@amitkeret

| rejectattr('entity_id','match',...)

YES! Home Assistant finally supports this! I finally got around to implementing it on this sensor (well, more like documenting it).

@Snuffy2

Is there anyway to modify it to only show if an entity has been unavailable for XX seconds/minutes?

I've updated the sensor and this is now accomplished with a much more elegant method. I recommend updating to the new method.

Jazzy, Just wanted to let you know that the package has been working like a charm and I wanted to thank you for making it available to all of us. I put in place the light only entities as you explained to me and it works like a charm. I have been reading the notes which are very detailed but because I am still learning about HA as I transitioned from smartthings and a quick question id I can. My unavailable entities show the lights and their groups as well as all the others as you would expect. I know I can enter them all one by one in the ignored_unavailable_entities group but is there a way to enter them using a wild card like approach foer example light.* or light.group_*. Anyway I really just wanted to thank you for al your help Ian This message is confidential. It may also be privileged or otherwise protected by work product immunity or other legal rules.

@Bytelink5616 My pleasure! I'm just paying forward all the help I've received along the way :-)

Can you visit the new repository for the sensor and check out the READ.ME? I've added quite a bit of documentation there.
If you still have a question then feel free to open an issue there so others can benefit.
