Working on the tutorial for Weather Station, resolved the issues I had earlier with this but now after using the Weather Station Demo sketch I get no display . I am using the WeMos D1 mini , 3.3 to vcc, G to gnd, SCL to D4 , SCA to D3.
I noticed that in your tutorial it calls out WeMos D1,R2 & Mini, could that be the issue, I am using the wrong board?

Hi Larry.
I’m not sure what might be the problem. Can you try these suggestions?
- Select another Wemos D1 mini board;
- If selecting another Wemos D1 mini board doesn’t work, try a Generic ESP8266 Module;
- Try powering the OLED display with 5V.
Let me know the results.
Regards,
Sara

So it’s up and running , thank you. I didn’t have to change the 3.3 to 5v , when I tried to use generic ESP8266 and for some reason I got D3 not used . What actually did work was to use the LoLin (WeMos)D1 & R2 mini , so once again thank you.
On my display it shows Mon 8.03.2021, is there someplace where I would change it in the sketch , I am not sure exactly how I would do this task.

Great!
What do you want to modify?
To modify the date and time on the display, you have to take a look at the drawDateTime() function on the code.
