Some flow ideas if you like.

### Auto remove certain ‘Low Battery’ notifications by Homey, most of the time annoying and useless when a device uses rechargable batteries, like robo mowers, and robo vacs

- This flow is triggered by new timeline notifications,
- If it matches the phrase you enter as argument to this Homeyscript card,

(_find the used script below_)
- 
  - in this example: ` **My_Mower** is low on battery` (an exact part of the original message in the Timeline notification),

- _Then, it removes the timeline notification right away_  
.

- Detail of how to enter the search phrase argument

#### The slightly adjusted script:

- 
  - the argument is used with line  
`const containsText = args[0]; // Only deletes notifications that contains the specified text`

- 
  - The script returns the used argument along with the ‘flows removed’ message

- 
  - Note: the categories list is my own, but it is not used here
