This is definitely my scenario.
No other intelligence is involved so the Rpi was one-stop-shopping.
I had thought about an Rpi Pico, but again, it would not have been as

Yes, that is exactly what I was planning to instrument. Maybe

I'd say one problem would be relative inefficiency and overheads: you have
one process talking to the device to extract data, save it
Is that with both UPSes on same machine?
A quick guess would be that insufficient data points to identify the device
are configured (vendorid, productid, serial...) in ups.conf, so both
drivers connect to the first match. I'd expect them to conflict and one
would die or both loop reconnecting, if

Thank you,
I will take a look at the i2c drivers you mention as well as your notes.
As I noted in my previous post, I currently like the looks of the ina3221
i2c device. It has a 16-bit ADC, can measure 12+ volts directly, it has 3
channels, and it can sense current. Although I probabl

Hi mailing list,
I looked at all FAQ and docs and can’t find a solution.
I installed but on both Kali Linux and Ubuntu.
(For comparison purposes)
I’m trying to connect and monitor two UPS APC via usb.
One is a back-ups bx1400 which I can see via via upsc.
The second one is a more recent one smc 150
