True what Arnt says, but it’s an issue of those devices **combined with Homey**.  
It is not always a flaw of the device:

I have Aqara contact sensors which batteries stay at 100% forever @ Homey  
But, @ zigbee2mqtt, it shows something different (it even shows the voltage);

It’s good to realize it’s just an _indicator_, not a measure instrument.  
And not all devices stop working at X% as well:  
One dies with 50% left, another could function with 10% left.

When batteries have less than 20% juice left, Homey automatically creates a timeline notification.  
_If that isn’t true, you’d contact support._

**You can create a daily report yourself** , with this (import-able) script + flow:

> [@The Flow Exchange(r) - Exchange Your Flows with Others!](https://community.homey.app/t/the-flow-exchange-r-exchange-your-flows-with-others/68981/36):
>
> Send a report with all battery levels When you’d like to receive an overview, with the battery levels of all battery powered Homey devices Apps used: [HomeyScript](https://homey.app/nl-nl/app/com.athom.homeyscript)[CallMeBot](https://homey.app/a/com.gruijter.callmebot/) - You can replace it with your own messaging app [Email sender](https://homey.app/nl-nl/app/email.sender) - Optional - just an example messaging app you can use HomeyScript code used (it’s included in the flow): (Updated @ March 2nd 2025) const devicesObject = await Homey.devices.getDevices({ filter: { class: 'sensor' …

.

Next to the timeline-to-push flow trick of Arnt, you can use this
