I just upgraded (through apt update, using raspbian) to 4.3.0 and am seeing the following error.
I'm using sdr to get data from an accurite 5n1. Tried some debugging on my own and can't even see where totalRain is coming from - rtl_433 uses "rain_in, and sdr returns rain_total

Normally, the driver does it, but if asked, WeeWX can calculate 'rain' from cumulative quantities such as totalRain, by taking a difference.
Your configuration file seems to be asking to do so, but totalRain is not available. As for why it's asking, that's not clear.
What does the section [StdWXCalculate] in your file weewx.conf look like?

I'm using an Accurite 5n1 - this has been working since early 3.x; just stopped in 4.3, I AM using my 4.2 config files and skins.

Try removing the line
rain = prefer_hardware
It's what's causing the StdWXCalculate service to try and calculate a value.
I wonder where that line came from. I don't recall it ever being part of weewx.conf

OK - thanks. Had a bit of a scare when I corrupted my config file and NOTHING would start. I commented rain and rainRate out of StdWXCaiculate and looks good now. I AM getting an N/A in RanRate om the disp;lay, but that's OK for the time being. Will check when we next get rain to see what happens.
It would be nice to know where totalRain came from - I tried grep'ing for it in all the .py files and only found it in accum and units. Before I posted, I actually commented those lines out and that did NOT work. Any thoughts on that?
Also, I notice from the log I'm still using Python 2, which is what /usr/bin/python points to by default on squeeze, which is what I'm running right now. Are there notes on how to force weewx to use python3?
Thanks!

The type 'totalRain' has been in the code for a long time. What I'm wondering about is where did the line
rain = prefer_hardware
come from.
If you are still on squeeze, you're best off staying with Python 2. Not all of the Python 3 pre-requisites are available through the repositories.

Don't know WHERE I got Squeeze - just checked and confirmed; it's Buster, so would definitely like to at least try to get rid of python 2.
On the rain = prefer_hardware, I looked at my old config files, and it seems it's "bounced" back and forth, probably depending on what version of sdr I had.. I honestly can't remember why.

If you're on buster, then it's simple enough to switch to Python 3. Basically, just follow the directions in the Debian guide:
wget -qO - https://weewx.com/apt/weewx-python3.list | sudo tee /etc/apt/sources.list.d/weewx.list
sudo apt-get update
sudo apt-get install weewx

OK - haven't tried Python3 yet - back on the rain issue. We've had some rain this morning, and it is NOT picking up in WeeWx; captured some debug this morning; but will not be able to look at it until later today or perhaps over the weekend. As I recall, this happened when I upgraded to 4.2 and one of fix (in addition to changes in sdr) was to add the "rain = prefer_hardware" line.
Will try to do some debugging over the weekend and let you know. Working on a Pi based Snow Depth detector as well, since we're getting snow now.
