How to numeric widget

Hi,
The numeric input widget currently has a bug on the iOS app (not sure if it also affects the Android version - you’d need to check) that causes the number to be sent as each number is entered, rather than the whole number being sent just once.
This will be fixed, but in the meantime if it does affect your OS, you’d need to work around that problem if you wanted to use it - maybe by adding a “go” button widget once the numeric value has been entered.

You might be better using the timer widget:
