hello all,
I was trying to add device (Node MCU v.3) and connect to my personal WiFi network but unfortunately the button is not possible to push, how to configure network credentials?
Thanks a lot for any advice.
Hi @eldiane. For some reason, this button is disabled until after you have added at least one "Variable" to the Thing. You can do that by clicking the ADD VARIABLE button.
If you have done that and the "Configure" button is still disabled, make sure you have selected your Device by clicking the "Select Device" button.
hello @in0, thanks for fast feedback.
I tried to add variable, but it also seems to be "blocked" (button is unavailable, and also "Declaration" field is gray - cannot add any text to this field)
Select device button works correctly, i can add device without any problem.
You need to pick a variable type from the "Select variable type" menu.

OK, I know right now what was was wrong. I do not pick "Boolean type" in "Basic types", right now everything seems to work correctly.
Once more again @in0 for fast help!

You are welcome. I'm glad it is working now!
The way to do that is by clicking the "[x] Solution" button at the bottom of the post that provided the solution to the topic. This is very helpful to do because it will allow others with the same question to find the solution more easily, and also allows the helpers to focus their attention on the unsolved questions.
I see you have already done that. Thanks!
