Hi, I need help with some flows. I want to give my cleaning lady a Tile (beacon). And register when she comes in, and when she leaves. Then i want to calculate the hours she worked so i can sent her a message on the money i ow her. Is this possible? I think i should use Logic for this and set some variables, but i really could use some help with this. Any ideas? ---

You could also install locative on her iphone or some other app when its android. I think presence detection is a way to do this. ---

Just to pay her, she sometimes work one hour, other times more then 3 hours. ---

The presence part isn’t the problem, i need help with the Logic part ---

Perhaps use the count up timer… Not sure if it is still available, but I do remember an experimental app that does countdown and count up. So, when present, start countup. ---

Using Chronograph helps. Now i can make a few flows: - when beacon in range, start stopwatch YYY - when beacon out of range, stop stopwatch YYY - when stopwatch YYY is stopped, calculate an value with Logic Then i think i have to set a Numeric Variable… and then i get lost… I can make a variable in More \> Logic \> New \> Type should be Number probably, but what do i fill in at Value ? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/7/37d13486e873d34b567794bf3933c41378320dad.jpeg) ---

> [@Jaap](#): > > when stopwatch YYY is stopped, calculate an value with Logic You don’t need to calculate, juist read the stopwatch value. That is what you wanted! ---

The stopwatch time/value is in Seconds. And i want to sent a message with the worked time (hours) in it. (So the calculation part must be something like Stopwatch value / 3600) How would you solve this? ---

You post the options of the when area. But you have to select the options in the then area. ---

I think to round a number you have to use the app „better logic“ instead of the bulidin Logic app ---

It works with the built in logic. No better Logic necessary. ---
