Exelent my dear.
Everytyng is done!!!
Sorry for my bad english.
Ah, thanks for reporting. We need to add this user to that group on Node-RED install already: DietPi-Software | Node-RED: Add service user to dialout group · Issue #5974 · MichaIng/DietPi · GitHub
Only the primary UART can be toggled on or off, and on the Zero W the mini UART is the primary one.

Understood. I want to share that everything works. The method I used in Node red is wrong, here is the correct approach.https://discourse.nodered.org/t/serial-port-loopback-test-rpi/72284
Thanks again.

I want to note a very important point, I added these two lines at the bottom of /boot/config.txt to make everything work as expected.
# Disable Bluetooth
dtoverlay=disable-bt

Even though bluetooth is turned off in dietpi-config without adding these two lines ttyAMA0 does not work.

Shouldn’t dietpi-config have more bluetooth options, or default to include these two lines in config.txt
Greetings.
