Endnodes communication via Node-Red on IOT Edge Computer not working

Node-Red
1

From my understanding of the device docs, the below flow should send a broadcast message to all endNodes, and get a response, but all 3 of our new endNodes (ASM1-3 and 2x ASM1-5) don’t respond at all.

Yes, they work over USB… Any help getting this working until I get can a USB modem?

Hi,

Can you please provide your online order number(s) so I can see what hardware you have and what options were selected when purchasing?

3

Also On the Address the last two octets should be FF
00:13:A2:00:00:00:FF:FF

4

Order #512604

@jacob Thanks; will try that.

Edit: the corrected broadcast address didn’t make any difference. I did try with specific device MACs too ofc.

5

The debug node should be connected to the lower output connection on the Gateway Node because technically EndNode is an unknown device(ncd-red-wireless, does not know how to parse responses from EndNode Devices).

6

Still no EndNode output after putting the debug node on the second gateway output connection. Endnodes don’t show any activity, just a green light. Other sensor data is received by the IoT Edge Computer and Node/ncd-red-wireless

I have tried sending other commands to the endnodes as well via this gateway code, but no change in relay or voltage is observed via USB control/alpha station.

Updated Node-Red Flow:

I see you have a Co2 sensor as well. Are you seeing data from that sensor on the Edge Computer?

Try setting the address to 00:00:00:00:00:00:FF:FF

8

Yes, the CO2 sensor data is being received just fine.

I just tried changing address to 00:00:00:00:00:00:FF:FF, and it worked for both ASM1-5 units. I am totally puzzled as to what changed, but addressing both of those devices directly seems to work now, and the status light flashes and I can change the voltage as expected.

However, the ASM1-3 unit seems to have another problem. It was ordered with 900mhz wireless, but Alpha Station shows “Wireless 2.4Ghz” under Device Configuration:
ASM1-3EndNode

9

Can you open the box and share the radio module picture? it just might be a glitch in the alpha station UI

10

It is an XBee Pro S3B as expected, so I am pretty puzzled why it won’t communicate when the other endnodes are working now (have one controlling a bank of lights already).

11

I was wracking my brain when I realized that I had connected both ESM 1-5 units via USB and Alpha Station, and set the encryption key (to the default NCD key), but I had not done the same with the 1-3 because “Wireless 2.4Ghz” threw me off. I tried the same thing - setting the encryption key - on the 1-3 unit, and it’s now communicating with Node-Red and the Edge Computer.

Looks like everything is working now.
