Envoy Driver

[weather list]

Working on getting Matthew Wall’s weewx-envoy driver running under Python3. I’m no Python guru but I think I have fixed the print() and Except: errors, but this one I don’t know how to fix:

WeeWx 4.4.0 (using new DB schema)
Python3
Intel NUC
Raspian Desktop Buster, fully updated

Running envoy.conf from the command line:

That’s not an envoy driver exception.  Rather, it’s a forecast extension exception.

Try installing this:

My bad, I had leftover Forecast extensions in that envoy.conf file.

With it gone, I get this:

 sudo bin/weewxd envoy.conf

Traceback (most recent call last):

  File "bin/weewxd", line 261, in <module>

    main()

  File "bin/weewxd", line 154, in main

    engine.run()

  File "/home/weewx/bin/weewx/engine.py", line 188, in run

    for packet in self.console.genLoopPackets():

  File "/home/weewx/bin/user/envoy.py", line 203, in genLoopPackets

    packet = self.envoy.get_data()

  File "/home/weewx/bin/user/envoy.py", line 259, in get_data

    resp = urllib.urlopen(self.url)

AttributeError: module 'urllib' has no attribute 'urlopen'

The hostname entry on the LAN is correct.
