The link on the app store “Bezoek forum” is not correct. It is linking to the Telegram page of the community. But the app Temporary Variables looks nice. ---

Maybe i am missing something, buth these are just tags, not variables: how can i change/update a variable and than reuse the first token but get the latest value? **Is this possible with this app?** That at least is what i and many more others need: in-flow variables. But unless i am missing something, this just looks (mostly) like the buildin create a text/number/yesno tag. ---

> [@Arie\_J\_Godschalk](#): > > Is this possible with this app? Not with this version, I could create a system for that. But you would have a new token everytime the variable changes. I can‘t think about a system that would currently allow to change a tag value after it was created. maybe i‘m missing something in the sdk, i‘ll take a look once I have some free time. ---

Yeah, i know, i have been banging my head on it also, allready tried it a couple of ways. But without a currentRunningFlowId it would need at least 2 flowcards to use and you would need the user to fill in the uniqueId-tag to retrieve the unique in-flow-value. So not very user friendly. But since the buildin (general) variables just requires one flowcard to set and no flow card to use, it is, at least for me, still the easier way (except that it is not scoped). ---

> [@Arie\_J\_Godschalk](#): > > you would need the user to fill in the uniqueId-tag to retrieve the unique in-flow-value. Yes and then u have global variables again in a another name. I mainly created the app for me to have a simple math card that doesnt require a text to int parse. ---

Would be very useful if you could add (better) support for multiple variables. Currently if you have multiple variables of the same type they all show up with the same name, so it is hard to identify them from each other. Maybe add a field the THEN card where you can name the variable? It would also be great if you could add an optional “with decimal points” field to the float variable THEN card. It would give us better flexibility. Sometimes I have to reduce decimals to 1 before I for instance send it to a device. Would be nice if this was possible to do at the same time as the number was created. ---

It would give us better flexibility. Sometimes I have to reduce decimals to 1 before I for instance send it to a device.

Hey wow, I was already looking for something like this! I expected this to be integrated in homey by default but wasn’t. Great job! ---

Being a newbie with Homey, I need some help to properly use your App. I have created a text variable “Scenes” which contains the following string : `Rest,#ffa028,Relax,#ffb854,Read,,Concentrate,#ffe8c0,Energize,#fffefd,Cool bright,#ffe3b5,Bright,#ffc875,Dimmed,#ffc671,Nightlight,#ff6c0ff` For testing purpose, I take the 2nd element of that string to put in a temporary variable, using the formula {{ (‘Scenes’.split(‘,’)[2]) }} ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/a/2a8f4b80f0151727bd6bff3d44d70574aad08073.png) But for some reasons, double quotes are added to the value ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/b/bb0af257977e97d8a4662a9b1469eb781ac5d996.png) And due to these quotes, my next card, assumed to get a, RGB code via the temporary string, fails: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/7/77df60032deb0f8bf800e53cfbfd808b337ab05c.png) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/f/df200d582058d83d248e044dcf6df850488a94ac.png) Any idea what I am doing wrong ? I guess it’s due to the formula (split) as I don’t get extra quotes when I use a simple text variable instead of a formula \*
 V. [\*]. I did try with a json in my variable Scenes instead of an “array”, and with a simple logic card to get the 2nd element, assigning next the result into a temporary text variable. Then, I get a value without double quotes: ```auto {"scenes":[{"name":"Rest","rgb":"#ffa028"},{"name":"Relax","rgb":"#ffb854"},{"name":"Read","rgb":"#ffcd80"},{"name":"Concentrate","rgb":"#ffe8c0"},{"name":"Energize","rgb":"#fffefd"},{"name":"Cool rgbght","rgb":"#ffe3b5"},{"name":"rgbght","rgb":"#ffc875"},{"name":"Dimmed","rgb":"#ffc671"},{"name":"Nightlight","rgb":"#ff6c0ff"}]} ``` ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/c/acb7befb1bce7a19dfcb0773717146a07c608d10.png) ---

That’s Homey side. I don’t modify the string at all. Use for this [HomeyScript](https://homey.app/a/com.athom.homeyscript/) ---

Hi, I am just wondering: How long and within which scope is temporary variable valid? E. g., I am using am advanced flow right now that is run every 15 min. - and I need to store a boolean value that is checked the next time the flow is executed, but I don’t need that variable outside of this flow

Only while the flow is running
