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.
@C.r.a.z.y. is this confirm? coz i'm having the same problem.
and Yes, i'm using serial for my gateway and usb for my sensor.
Please share if there's possible answer for this problem.
thanks

in the second test i used that getting started code to test the radio modules with a library other than mysensors. and they worked. (That code is not mine, i suppose it use the maniacbug library).
So i did investigate to find the differences between mysensors and that library. Only after replacing, in mysensors, the enablefeatures with that code, i got the communication gw-node.
I am going to rework the system so it uses an Easy Pcb and a Pro Mini rather than the Leonardo board.
I think I might be seeing a voltage drop in my point to point dupont wiring from the Arduino to the Radio.
I'll update you all once I get a chance to make the change.

Request is the way to go as far as i know. You also need to implement the method handling incoming messages though to work with the answer. There are some threads about requesting values from domoticz in this forum. (Haven't read them) but imo there are some values that can't be requested from domotizc so better check that and maybe change the variable type.
@mfalkvidd Thanks for your help. MYScontroller seems to be able to replace the gateway assignement. I was running it for troubleshooting and it assign ID that gateway already used.
So I created dummy ID in MYSController to ensure that node does not use the first one
@mtiutiu Thank you for the information! I will give it a try with the bluetooth module.
I use Home Assistant as the controller and store the relay state in the EEPROM (according to the relay example) and on top of that I have configured the node to send updates of the state (taken form EEPROM) to home assistant periodically.
