Hello, I am a beginner in node red and would like to save the data from the dht22 sensor in mysql and display via chart. I have already tried a lot but unfortunately without success.
Thank you so much!
After using #define MY_TRANSPORT_WAIT_READY_MS 1, I was able to see something on the display. Then I started looking for why the transmission wasn't working.
The problem was that the rs485 5V connection had a shaky connection.

Looks like you're completely correct.
I don't know if I've ever used that function to manually add something to the dashboard, or if it was only long enough ago that I don't remember doing it that way. When I saw that warning about it not being editable, I thought that was an issue that I needed to address. (To me, it sounded like I wouldn't be able to turn a light on or off, for example.)
However, if that is not needed, then I guess I'm set! Now all I need to do is compare my code to the example code and make modifications where necessary to make mine show up.
Thank you so much!!!
On my test node I have enabled Echo and am using if (message.isEcho())
It is working.
I have searched and searched and looked at the API docs but am still unclear :
If the node sends a value, should it be able to read that same value back in the echoed message.
I know I can use message.sender , message.type etc, but how would I print the whole echoed message and/or the echoed value.
