the problem is clear:

client.publish();

awaits two (pointers to) character arrays as arguments (as the errormessage clearly states), but you tried to pass one integer (buttonPushCounter) and I foolishly assumed it might also take string.

so maybe sth like

may actually work ...

thanks for the advice, but it seems like it's conflicting with an assignment at the beginning of the sketch...

char msg[50];

how can we reconcile this?


Arduino: 1.8.2 (Windows 7), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, 115200, 4M (3M SPIFFS)"

C:\Users\GADAWE\Documents\Arduino\node_ct_rgb_box\node_ct_rgb_box.ino: In function 'void loop()':

node_ct_rgb_box:136: error: incompatible types in assignment of 'char*' to 'char [50]'

msg = itoa(buttonPushCounter,msg,10);

^

exit status 1
incompatible types in assignment of 'char*' to 'char [50]'

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

The assignment is not needed.

works like a charm!

so much to learn about coding.... my have some follow up Qs to clean up and stabalize the experiment, but otherwise it's working!!!

thanks again!
