I have a usb modem (PR55-17A) and temperature/humidity sensors. In Node-RED I am receiving data from the temperature sensors every 10 minutes as expected.
I am now trying to see the remote sensors in XCTU using the networking scan tool as described in this video. I can add the usb modem in XCTU, but the scan never finds any remote radios.
I have tried the following:
- Forcing a data transmission from the temperature sensor by pressing the reset button
- Confirming that the usb modem is in Normal sleep mode
- Rebooting computer to make sure usb port is not in use by Node-RED
Hi @ben.fussell Unfortunately, you can only discover and access the properties of Modem devices within the network (acting as repeaters, for example), as these devices do not enter a sleep cycle. In contrast, NCD sensors operate in a sleep cycle and only wake up to send variable values to the Gateway/Modem, after which they immediately return to sleep. Therefore, it is not possible to discover these NCD sensors using XCTU.
Let us know if you have any questions.
Thank you,
Eduardo M.
As noted in the video you need to change the Network ID of the USB modem to 7BCD, then you would need to put the sensor into configuration mode. By doing this you can see the sensor in a network scan because when the sensor is in configuration mode it keeps the wireless module awake. Just make sure you take the sensor out of configuration mode when you are done because it will quickly drain the batteries.
