# 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

 ![Screenshot from 2022-11-01 02-24-12](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/b/5bce8e26a32169a2aa96ac4fcda03c2ef9b33c03.png)

### 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)

```auto
const devicesObject = await Homey.devices.getDevices({ filter: { class: 'sensor' } });
const deviceKeys = Object.keys(devicesObject);
const batteryLevels = [];

for (const deviceKey of deviceKeys) {
  const device = devicesObject[deviceKey];
    const batteryCapability = device.capabilitiesObj?.measure_battery;
      if (batteryCapability) {
          const batteryLevel = batteryCapability.value;
              const deviceName = device.name;
                  batteryLevels.push({ name: deviceName, battery: batteryLevel });
                    }
                    }
                    batteryLevels.sort(function(a, b) {
                        return a.battery - b.battery;
                        });
                  
                    const batteryInfoText = batteryLevels.map((device) => `${device.name}: ${device.battery}%`).join('\n');

console.log('Battery levels:\n' + batteryInfoText);

return 'Battery levels:\n' + batteryInfoText;

```
