db Not recording rain totals

[Jonathan Emmert]

I've had my station setup for the last 4 months, and it has never recorded rain amounts. I've confirmed that the station is broadcasting, so I'm assuming there is a configuration or unit conversion issue somewhere, but I'm not sure where to start.  Any thoughts?

• Station: Vevor7in1
• Capturing via RTL_433

I've attached my config file for reference.

Have you checked to make sure there's nothing blocking the rain sensor bucket? Do you have access to it?

Yes, I've confirmed that the sensor is unblocked, and that it is working. The Vevor base station records the amounts correctly. I have also confirmed that RTL_433 is able to see the rain totals. I just am having trouble getting it from there into the Weewx database

Here is the raw data being pulled in by RTL_433:

Alright - I may have found the issue. It looks like in the sdr.py file there were 2 Vevor class sections, and the second was overwriting the first. I've got rain coming in shortly and will see if it updates correctly.
