Stopping UDDynamic and UDChartJSMonitor gracefully?

Is there a good way to stop a UDDynamic or UDChartJSMonitor? (Or I guess any other auto-refreshing component?

An example of what I’m working on is below… Enter in a Computer Name you can ping and click “Monitoring” and enter in the minutes to ping the device…

Essentially, if I am pinging a computer for 1 minute, I want the UDDynamic to run 60~ times (probably closer to 58-59 depending on how long it takes to run the scriptblock) and then stop. I then want the monitor to preserve the current state, but stop refreshing.

Hello, you can stop the autorefresh like this :

Set-UDElement -Id $Id -Properties @{
    autoRefresh = $false
}
