Help reducing battery low warnings in flow

[Peter_Kawa]

@JanPieter88

Yes, the same with my robot-lawnmower that floods the timeline with ‘warnings’ about its battery every day. I wish it were possible to exclude certain devices’ energy warnings from the timeline.

You can file a request at homey.app/support, but I think chances are pretty low

But here’s a workaround

@Peter_Kawa

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

(original script by @Caseda)

show me the script

// DEL timeline msgs ALL matching | Argument = searchphrase - Timeline_Wrangler v1.3p

// ==================== User Settings ====================
const deleteNotifications = true; // If "true": actually removes notifications, if "false": display only
const daysOld = 0; // Amount of days that need to have past before a notification is deemed old
const hoursOld = 0; // Amount of hours that need to have past before a notification is deemed old
const maximumNotifications = 250; // The maximum amount of notifications that stay, anything more will get deleted
const containsText = args[0]; // Only deletes notifications that contains the specified text, Empty ( '' ) = not used
const showCategories = false; // If "true" it will show all timeline categories you have and had in the past
const useCategory = false; // If "true" it will only remove from the specified categories below

// Separate categories by comma ( , )
