Values not presenting in DisplaySSD1306

[Getz99]

@user2684

Hi, I have a problem with values not showing in the DisplaySSD1306.

I have made a temperature and distance node with a Ds18b20 and a VL53L0X and also connected a DisplaySSD1306. Debug and sketch below. The thing is the values from the sensors are showing up correctly in the controller but the not in the display, only 0.00 is presenning in the display, any ideas of what is wrong?

Thanks!

@getz99 Can you do us a favor and edit your post and highlight your code section and click the "</>" icon to convert it to a code block. It makes it much easier to read.

Thanks

@getz99 I remember we had a similar issue with the display before releasing v1.8 but I was sure it was fixed. Do the values stay at 0 forever or just at the very beginning? Meanwhile I've opened https://github.com/mysensors/NodeManager/issues/469 so to track this down. Thanks

@user2684 the values stay at 0 forever in the display, everything else is working fine. Thanks

I have a motion sensor, DHT22, and DisplaySSD1306 connected. I am experiencing the same issue. The values are read from the sensors and sent to the controller. However, the display shows lines for battery, DHT22 temp and humidity, and motion, but they are showing 0 for values.
