UPDATE
I believe there is an issue when using a DFRobot AS3935 with weewx. Here is
what I did:
1. Connect DFRobot AS3935 to RPI.
AS3935 >>>> RPI
------- -----
Red >>>>>> Pin 4
Black >>>> Pin 9
Blue >>>>> Pin 5
Green >>>> Pin 3
IRQ >>>>> Pin 11
GND >>>>> Pin 14
2. Apply power to RPi and ensured I2C Interface is enabled on RPI.
3. Verified that you can detect the DFRobot AS3935.
pi@raspberrypi:~ $ i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: 03 -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

70: -- -- -- -- -- -- -- --
4. Install Required AS3935 Module (https://pypi.org/project/RPi_AS3935/)
4a. sudo pip install RPi_AS3935
5. Install Required AS3935 Service
5a. Download the file (
http://lancet.mit.edu/mwall/projects/weather/releases/weewx-as3935-0.6.tgz)
5b. Install AS3935 Service --- pi@raspberrypi:/home/weewx/bin $ sudo
./wee_extension --install=/home/pi/Downloads/weewx-as3935-0.6.tgz (Paths
may differ)
6. Followed the remaining instruction found at
https://github.com/weewx/weewx/wiki/as3935
The error that I'm receiving when the DFRobot AS3935 is connected to the
RPI is as follows:

When I connect a MOD-1016 AS3935 detector everything works as expected.
