S_INFO NODE with OLED Display - Solved -

[scribere8146]

Hi, this is my code for writing Text to the oled display.
Controller is ioBroker and so far everything is working, but... I like to place multiple lines to the display using V_VAR1 - V_VAR5. How to use them?
And do i need a ACK Command?

Thanks for you help, sorry this is my first "self made" node.

 * network topology allowing messages to be routed to nodes.

@awi got some examples in Domoticz: https://forum.mysensors.org/topic/1957/lcd-clock-and-text-sensor-node-with-new-v_text I dont know how this works in ioBroker with v_var though.

Hi sundberg84, using 5 Nodes was my first idea. But i want to use V_VAR1...
But you solved me problem indirecty. I installed MYSController and...the code (updated above) is correct.
Looks like ioBroker is my problem.

Thanks for your help Thorsten

Made small update .....X,Y Pos Fontsize...
