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

Hi,

could it be that there is a litte bug in the mysensors adapter for iobroker?
The MYSensors API say that V_VAR1 .. V_VAR5 is possible for "any Device".
But I can't use them with S_INFO.
The MYSensors Controller can Handle this.
So i edit the getmeta.js like this
'S_INFO': {index: 36, role: 'info', vars: ['V_TEXT', 'V_VAR1', 'V_VAR2', 'V_VAR3', 'V_VAR4', 'V_VAR5']},

With this modification, it works...

Regards Thorsten

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

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.
