Hi

nextion enhanced
Arduino mega
dht22 sensor

I have been using an example tutorial I have set up everything correctly
temperature and humidity.
In nextion editor I have 2 text temperature humidity when I test in debug the values change and works okay.
nextion screen the 2 text show up but the values don't change.
nextion screen blue wire to 1tx yellow wire to 0rx to Arduino.
I've even tried another example.
Enhanced screen is that my problem.
If anybody point me in the right direction or have an example file just a small one so I can get to understand it thanks
I have enclosed a file I don't know if I've sent it right.
And as usual thanks Paul

What Arduino are you using?

nextion screen blue wire to 1tx yellow wire to 0rx to Arduino.

will only work on a Mini without attached USB/TTL Serial adapter, a Micro ord Due (?)
(but then you would need to use Serial1 and not Serial).

On the other platforms it will not work, because there is already a device attached to Serial (pins 0 & 1).

Swap Nextions connections, Yellow to Pin 1, Blue to Pin 0.

Don't use the USB side at the same time. I.e. No serial monitor or similar to Nextion Editor.

Your command format is good, you should be good to go :slight_smile:
