FWIW - I did get this to work on v5 beta with some tweaks in my install
script solely due to the weewx commands being a little different than v4
and earlier, but it was a little bit of a struggle here too. I had to do
a lot of plugging/unplugging the rtl_sdr dongle as it seemed to lock up
with device in use when I was trying to run things in the foreground.
Eventually weewx succeed interactively before I tried it from systemd....

In repeated previous repetitions I got the following and needed to
unplug/replug it to get it to release.

I have no explanations other than to guess (guess...) that you just need
patience to let the device get acquired and hear something. It does take
quite a while so you might go a couple times through the 'waiting 60
seconds than retrying' attempts til rtldavis gets its brain straight.
But it does seem to work in current raspi os with the current v5 betas...
[Rtldavis]
cmd = /home/pi/work/bin/rtldavis
transceiver_frequency = US
iss_channel = 1
anemometer_channel = 0
leaf_soil_channel = 0
temp_hum_1_channel = 0
temp_hum_2_channel = 0
rain_bucket_type = 0
debug_parse = 3
debug_rain = 3
save_pct_good_per_transmitter = False
driver = user.rtldavis
Lastly - these debug settings are 'really' chatty. Like really REALLY
chatty. So probably don't leave them set to 3 for long for your SD card
life.
