I can fill it as number when creating it but I can’t set it in a flow… it’s the cost for one KWH to calculate my use of energy! ---

I would then still calculate everything 100 times higher and divide by 100 when appropriate. ---

Will try that! Thanks! Maybe it’s only possible in older versions because a saw an example in the ‘washing machine flow’ from @Rocodamelshekima ---

It didn’t work in the mobile app, but it did work on the Homey Web app! ---

is it possible to convert a logic variable **hour** into a(nohter) login variable **hour in decimals** so for example **13:45** would become **13.75**. Not sure how to do that. ---

Okey, the forum edit is deleting the dollar signs. You should write ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/a/ca4d1416761b8c63fa4c35beb2659a084a48fdc0.png) Noticed also that you use some variabletag in the calculation Zonsopkomst? Remove it. The number() function will convert the hour and minute values into number format. ---

Yes in normal logic but I’m using better logic app ---

> [@peltsi51](#): > > Noticed also that you use some variabletag in the calculation Zonsopkomst? Remove it. The number() function will convert the hour and minute values into number format. Hi @peltsi51 The ‘Zonopkomst’ tag is the dutch version of SunRise. Which is the actual value I need. So at 00:01 I will run the flow ones, that transforms the SunRise time for that day to a real number. By the way this works, with the current time, as you instructed. But I need to calculate that from a time in the Sunrise tag. ![2021-01-27 09_11_16-Homey van Twan en Patricia](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/5/c5c431b687e77b6230e2880531a0b965763ee4da.jpeg) ---

No problem. But why can’t I use them? I have seen earlier in this topic that tags are used. Or is the problem that the tag I’m using is a text tag? ---

I think there isn’t any function in the better logic or mathjs that could divide the :-separated string into two variables. So you propably have to use homey script to do that ---

yeah, for now, I will run the calculation of sunrise at the sunrise time, and sunset the same. So for the next day, these times will be fine (more or less) the 1 or 2 minutes difference does not make a real large impact.
