EmonBase can't open serial port

grod55 · 2024-10-17T22:05:46.575Z

I am repurposing an emonBase purchased in 2023 to use as a data collection point for multiple emonTHs. As I wasn’t sure how it was previously configured, I downloaded the latest emonSD configuration and then did a full update.

Unfortunately, it does not recognize any emonTH, even if I manually enter it into emonHub as a node. In looking at the emonHub log, it looks like the emonBase failed to open the serial port /dev/ttyUSB0, and then failed to connect to the RFM69 module. There is nothing plugged into the emonBase other than power, ethernet, and HDMI. Also, I have reflashed the SD card a few times to make sure nothing happened during the image-writing process.

Below is my emonHub log showing the errors.

Any help is greatly appreciated.

thanks,

I see from your debug that it’s using the LowPowerLabs interfacer, perhaps your emonTH are using Jeelib Classic firmware?

Edit: I don’t think that’s the problem, sorry.

Started a new post here as the issue doesn’t look to be the serial port.
