Low battery level detection & notification for all battery sensors

msex67 · April 1, 2022, 11:11am

Yes, template for sensor ? how do i use that ?
This is my action:

mtrista · April 1, 2022, 6:05pm

All you have to do is insert {{ sensors }} into your message so it’ll be replaced with the actual list of low battery entities. So change “low battery” to, say, “low battery: {{ sensors}}”.

Thanks, works like a charm.

hi Guys,

anyone have problems with a notify by xiaomi Devices?

lymbada · April 8, 2022, 1:54am

Thanks for the blueprint, a good kind of catch-all of my devices. However I needed to be able to have it trigger multiple times per day (every 1/2hr or there about), so I took a fork of your code & swapped out the ‘time’ for ‘time_pattern’ to allow for my specific case.

Home Assistant Blueprint: Low battery level detection & notification for all battery sensors with Time Pattern (github.com)

rcblackwell · April 8, 2022, 2:12pm

@lymbada, Nice adoption! Thanks for this. A question regarding wording for minutes and second settings Descriptions for these settings read in part "When to trigger, ‘*’ for any hour, 0-59 for the specific ". In the case of minutes, should the word hour not be replaced with minute, and in the case of seconds, should it not be replaced with seconds?

EDIT: Just noticed an issue that needs to be addresses. I’ve set the attributes to perform a check on the 55 minute mark. The automation (Blueprint) discovered a device with a low battery. It performed as it should have, sending a message to my cellphone. Problem is, it continued to send the same message every two seconds until the time passed 55 minutes. I received 30 messages on my cell. Each, 2 seconds apart. Is this the intended behavior of the blueprint? If yes, how do I configure the automation such that this behavior doesn’t occur?

rcblackwell · April 8, 2022, 6:34pm

Okay, figured out the problem! With hours and seconds set to “*”, the action is fired every other second. To get around this I set the seconds to 1. Now the message is sent once, 1 second after the specified minutes.

lymbada · April 8, 2022, 9:55pm

Hey rclackwell
I had indeed done both of those updates for the description, and also set the default for second to ‘1’ (as I found the exact same thing, I guess time-patterns is not the same as typical cron).
I guess you had an earlier download… or I forgot to publish the changes? I’ll check now.

@lymbada Hi Matt,

The blueprint I’m using came from git yesterday. It matches what I see posted today. I see there is a default of 1 for seconds. Perhaps the blueprint shouldn’t allow “*” to be utilized for seconds? Only allow 0-59. Now that I understand how time works, I don’t see a situation where the wildcard would/could be used. Eliminating the wildcard choice would eliminate the problem I (and you) saw earlier.

As for descriptions; the minutes and second description still read in part "When to trigger, ‘*’ for any hour , 0-59 for the specific ". In the case of minutes, should the word hour not be replaced with minute , and in the case of seconds , should it not be replaced with seconds ?

Great blueprint, thanks for sharing.

If I trigger the automation manually, I get a message without any sensor. Makes sense because all batteries are good. But in that cases I don’t want a message. Can I do this?

tykeal · April 25, 2022, 4:34pm

Manually triggering the automation is always going to do that. It’s designed to only send a notification if there is something to send when it runs normally. However, when you run it manually HA will skip all the trigger conditions and you’ll end up with empty sets and so it just sends you an empty message, essentially validating that your notification setup is correct.

Sorry, the blueprint works. I have use another service to notify my device, now it works perfectly

McFarTech · May 3, 2022, 9:05pm

Hi.

I have setup your BluePrint and when i click the run actions button I see the below pop up on my iPhone.

A couple of questions \ issues. I don’t see all devices in the pop up message. Also clicking on the alert does nothing other than take me in to HA. Is there any way of it taking to me a page I have setup with all my batteries?

dave_t_uk · May 4, 2022, 5:24pm

I think It is possible to provide a url to link to. Sometimes long press will give you more information as well?

If I try to add {{sensors}} I get this error:
Visual editor is not supported for this configuration

Templates not supported in visual editor
You can still edit your config in YAML.

At the moment I get a notification, but I dont have any batteries that are low. And I’m trying get the automation to show what entity is low

rcblackwell · May 22, 2022, 1:56pm

I received the same warning. Overcame it by opening the yaml editor and adding code there. Here’s my code for notify.

service: notify.notify
data:
  message: >-
    A battery in the sensor named {{sensors|replace("_"," ")}} is reporting a low state.

nikee · May 22, 2022, 2:10pm

I only get this as a notification:
A battery in the sensor named is reporting a low state
