Extract Sensor data

[MartinSokolov15]

Hi, i use XBee module with board, that use breadboard, on which we can attach simple sensors. I use this nodehttps://flows.nodered.org/node/node-red-contrib-xbee , to ''listening'' for data and I tried to extract sensor data via xbee api node and function node with msg.payload, but in the debug node i don't receive anythin. Any help?

It could be many things, here are 2 that I think could help:

• Make sure your XBees network is configured correctly for each Xbee
• Check the connections between your XBee and GPIO on your Raspberry

best regards!

I checked the connections via XCTU software I don't use RPI i connect it directly to PC

Ok, let's try this, with XCTU should be able to debug that XBees are reading and transmiting sensor data.

Could you try this? If all of this looks correct, then it may be a configuration thing to check with the NodeRed nodes, specifically the configuration nodes where you specify the COM port, etc for the RX and TX nodes.

Also you may need to send a command to the XBee to enable reading the sensor, or it can be configured to make it automatically. But with the XCTU you may check that.

Best regards!

Also, Node-RED has a very useful command to debug what's happening within the flow Try the node-red-log command line utility (should included in your Node-RED installation) and look for any error messages.

There are more logging options in this link that may help to understand what's happening in Node-RED: https://nodered.org/docs/user-guide/runtime/logging

Closing for now, feel free to reopen if you find an issue with the library

best regards!

I try this, but in the video not all configs are visible, so i could't repeat them. Can anyone please help me? https://www.youtube.com/watch?v=K-jov9Cvxcw&t=46s

Hi, i try this example, but i can't see the message ''Hello'', that supposed to come up and i've got this in the debug node. Where can be my mistake?
