Monitoring devices for low battery / offline

[strange flicker]

I currently have 2 automations. One for sending a notification when battery level is below 10%, and another for devices being unavailable (meaning they disconnected or the battery died). Wondering what else people do for this, and if there are better options out there?

Hi @strange flicker,
Putting this into a search engine might get you some ideas.

site:community.home-assistant.io battery low

[strange flicker]

alright

Aaron, this might be a good start https://community.home-assistant.io/t/low-battery-level-detection-notification-for-all-battery-sensors/258664

[strange flicker]

Do you use that

[vernal swan]

I have. I just have a conditional section on my dashboard that shows me my battery entities + levels on command now though

[strange flicker]

like this?

[vernal swan]

Yep that works!

I have way less.

Then I have a binary sensor to show/hide in the dashboard.

[strange flicker]

did you have to do anything for the colors to change when it gets lower with that?

[vernal swan]

Nope

[strange flicker]

I'll probably change to something like yours where you only shows up when the % is low. would you mind sharing that?

[vernal swan]

As long as color is set to state

When I’m not on mobile sure.

[strange flicker]

alright. i have a page with just sensor spam on it for glancing at stuff. probably add that to it

i have a lot of sensors

guess im curious, you need to have a visibility condition for each one eh?

I use auto entities from HACS for the visual aspect and then a script that loops over all battery devices and reports as persistent notifications and/or TTS otherwise, but the auto entities is clean and simple to use - and when paried with battery entities it does a nice job.

I have my ENTIRE battery section hidden unless I want to see all of it at once. If you want to do it per entity, it's just this on each tile:

type: tile
entity: sensor.shade_livingroom_backyard_battery_level
name: shade yard
visibility:
  - condition: numeric_state
    entity: sensor.shade_livingroom_backyard_battery_level
    below: 20

Or you can do what CO4x4 stated too. TONS of options.

My dash is actually broken up into multiple areas - one is batteries nearing depletion and one that's hidden is every battery entity in the house (of which there are numerous). This cat can be skinned in a lot of ways (and cat skins make good slippers FYI :D)

[strange flicker]

i like that, its just going to be a pain because i have so many devices to build at once

[vernal swan]

you can do it! Good luck!
