[solved] need help by mqtt imports on an oled display

#1 Post by tklein.lotte@web.de » 31 Mar 2017, 10:42

hello,

can somebody please explain to me why mosquitto_pub -t wemos/line2 -m "14" update the display on an wemos d1 mini (esp mega) and this one mosquitto_pub -t Wemos_Schlafzimmer/line2 -m "12" doesn't work.
The device ist named "Wemos_Schlafzimmer" and the original path of OpenHAB MQTT ist default.

Greetings
Thomas

I think you forget the first "/" in your publication. By the way I go with the MQTT standard of not having a leading / in my topics just because of this problem you are facing.

You either add a / in the beginning or change the controller setting by removing the leading / in both publish and subscribe field.

thx grovkillen.

I've found the stupid mistake. Under my MQTT Import device the string contained "wemos". I'll test you informations.
