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.
@Ethan-Chua Some photos of the wiring and set up would be of help here along with a link tothe radio modules you are using. Maybe try moving them further apart, counter-intuitive I know but it might be receiving module being swamped with the power of the TX one. You could also try a different channel (use nrf doctor to find where there are 'quiet' areas) and see if that helps.
Do you have a lot of bluetooth/wifi in the building? anything else in the 2.4GHz band like cameras, keyboard,mouse etc?
@Ispandy, let resume some things because I'm lost
You copied the sketch code from node 3 (= correctly running node with cardscans and remote control from openhab) to node 50 and you adapted the node id.
This same sketch on node 50 is running correctly with cardscans but not with openhab? Correct?
If above is correct: somewhere your openhab configuration for this node 50 is not correct. You say that node 50 is never receiving the openhab command, so there is a problem with your openhab configuration for node 50.
mfalkvidd gave you a great link, but if you ever need to see any possible choices, you can run
./configure --help
and it will show you. The extra flags section is one thing (of many) that it says.
Actually, this is very timely for me, as I'm trying to troubleshoot my own radio issues, so I'll use those extra two flags that you mentioned and see what they say.
Thank you!
I have checked with ethernet port instead of serial:
sudo ./configure --my-debug=enable --my-config-file=/etc/mysensors.conf --my-transport=rs485 --my-gateway=ethernet --my-port=5003 --my-rs485-de-pin=7 --my-rs485-serial-port=/dev/ttyS0 --my-rs485-baudrate=9600 --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18
The results is:
The gateway works with nodes as expected - no need to hit Enter for updates. It works as daemon as well.
So why it not works on gateway with serial? My suspicious is the port - I was using fake ones (/dev/ttyMySensorsGateway and /dev/ttyUSB020) and the real one /dev/ttyAMA0. Always the same. I tried to listen the (fake) port with "screen" command - nothing was there.
I have another finding/problem. When the gateway starts:

... you can find that instead of IP address (I was expecting 127.0.0.0 or 0.0.0.0) I get a garbage:
DEBUG Listening for connections on F▒▒:5003
After another trial (make clean -> ./configure .... -> make I get similar but with different "garbage":
DEBUG Listening for connections on ▒ݾ:
Home Assistant is unable to find the gateway on ports 127.0.0.1 and 0.0.0.0. I tried local network IP (static) - it was "accepted" (no connection error returned), but no Nodes has been found.
I'm really stubborn to find single board solution for Gateway (RS485 nodes) and Controller but I'm getting tired :(.
