[Solved] Logica, How do I add a variable to a (text) string?

Vonkenboer

Hi,

Just a noob question, how do I add a Logica variable, which is set in flow one, to a string in flow 2?

Tried $var_name, {{$var_name$}} which doesn't seem to work. Probably it's simple and documented but I can't find it. Please help me out here...

It's {{{$var}}} if I recall correctly. 
Remove the underscore, didn't work for me either... 

Vonkenboer

Wow, that's a fast response! Thanks!
What do I have to use? $varname or {{$varname$}}? Can give you me the syntax?

You define it with a logic card, just use varname. 
Then you can use it in for example a speech card like 'the content of variable is {{{$varname}}}' 

Vonkenboer

Okay. Clear. Thank you very much!

Interesting, I'm new to working with variables and varnames. Can you share a practical example how you are using this feature?

I using the Telegram app, made by jorden, to send log and device states. Also using it for status updates from communications between my Fibaro HC2 controller and the Homey.

Can you use a variable in a telegram message? i can't get it to work

I use the Better Logic app to do that. The examples shows a flow I made for testing/logging changes of variables. It will store a telegram message into a variable and one second later (delay) it will be reset with a <space>


The card underneath the  if column is filled with a space, to block second messages when I handled a string-variable  I will reset it with a <space>. (a trigger will not be activated when you send a Telegram with the same message content, so I have to reset it every time).

I prefer using Better Logic also, but unfortunately you can't use them in every action card. That's how I learned about the build-in variable function.
