 By default Battery Notes filters the device list to only devices with a battery, if you want to add a battery note to a random device then you can disable this filtering by adding the following configuration to your `configuration.yaml` and restart Home Assistant to see all devices.
 ```
 battery_notes:
   show_all_devices: True
 ```

+## I only want to add notes to a few devices, can I disable auto discovery?  
 If you want to disable this functionality you can add the following to your `configuration.yaml`, after a restart of Home Assistant you will not see discovered battery notes.
 ```
 battery_notes:
   enable_autodiscovery: False
 ```
 
-* I don't want to track battery replacement, can I disable this?  
+## I don't want to track battery replacement, can I disable this?  
 Yes, you can add the following to your `configuration.yaml`, after a restart of Home Assistant *new* devices added to battery notes will have the battery replaced sensor and button disabled.  Any devices you have previously added to Battery Notes you will have to disable/enable these sensors manually, which also means you can just enable specific sensors of important ones you want to track.
 ```
 battery_notes:
   enable_replaced: False
 ```

+## How do I create a battery low template  
 The best way to do this is to test in the developer tools/template section for your sensor.  
 Be aware that Home Assistant shows friendly alternatives for some sensors, so when you are seeing Normal/Low this may really be a bool, testing in the template tool will allow you to determine the correct template to use.  Start by adapting one of these.

 Once you have got your template correct you can copy/paste it into the battery notes configuration section for that device and it will use that for detecting the battery is low and raising the battery notes event.
