Thanks for all the help. I have not been able to rework the code yet, but I will take that as a working thesis and consider this problem closed. I really appreciate your help and patience as I work my way through this.

@jkandasa,
I also looked at my logs, and mostly they say this:

@jkandasa,
Sorry it took so long to get back to you. Here is my configuration screenshot:

And here is my gateway sketch:

/**
* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.

*******************************
*
* DESCRIPTION
* The ArduinoGateway prints data received from sensors on the serial link.
* The gateway accepts input on seral which will be sent out on radio network.
*
* The GW code is designed for Arduino Nano 328p / 16MHz
*
* Wire connections (OPTIONAL):
* - Inclusion button should be connected between digital pin 3 and GND
* - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
*
* LEDs (OPTIONAL):
* - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs
* - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
* - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
* - ERR (red) - fast blink on error during transmission error or recieve crc error
*
* Samuel Mills uptated this version for his personal use.

@jkandasa. Thank you for taking the time to help. I am using the USB-TTL connection to my gateway.

Hello,
I am running mycontroller on an RPI3 with a serial gateway. My gateway includes a DTH11 sensor. My second node contains a DTH11 and BMP 280. My nodes communicate via NRF24L01+. When I view the gateway node via the serial monitor in the Arduino IDE (or putty), I can see values from both nodes, and all sensors. I also get a green Rx light on my gateway with every expected Tx of my second node. When I launch mycontroller "sudo ./start.sh" and log in with a web browser, my gateway and first node show green on the topology graphic. I do not receive any values from the DTH11, and there is no indication of my second node. After about 10 minutes, my first node appears dead to the controller. I have deleted and re-installed my gateway to no avail. I have also completed the troubleshooting under the thread "Frustrated Newbie" and after reconnecting my gateway, the auto detect found the first node, and one sensor, but not the second node or all sensors. Please help me correct this issue.

Thank you all for the help. I added my user to the tty group and was able to connect to my gateway.

I have deleted and re-installed the gateway with the correct port name.
I also ran the command you requested and returned this result:
crw-re---- 1 root dialout 188, 0 Jan 4 06:26 /dev/ttyUSB0

Thanks for the help

Yes, that was a typo, unfortunately it did not fix the problem.

I have installed MyController on a Raspberry Pi 3 and have built a serial gateway with an Arduino Nano and uploaded the example sketch. Based on the serial monitor output read in the Arduino IDE, the gateway is working, and receiving data from my other sensor. When I attempt to add a controller from the MyController resources page, I get "Error: Unable to open!" for the status message. Under connection details, I have listed
"Port:/dev/tty/USB0, BaudRate:115200, Driver:Auto[jSerialComm], RetryFrequency:60 Second(s)"

I have selected each of the driver options, but they give me worse (and more clear) status messages.

Any ideas on how to over come this issue?

Thanks
