All,
I am trying out 2 different tasks. First is to confirm that I can make
weewx run on a raspberry pi before I move from wview and then to automate
the collection of data from our enphase envoy system. This post is
regarding my second task which I am trying out on a different raspberry pi
from what I will use to replace my wview system.
System:
raspberry pi 4b
latest os
WeeWx 5.0
So far:
WeeWx runs using Simulator
Installed Matthew Wall's driver
- weectl extension install /home/pi/weewx-envoy.zip
Then ran
- weectl station reconfigure
but obtained these warnings and errors:
*Warning ---*
*Choose a driver. Installed drivers include: 0) ?
(user.envoy) Missing parentheses in call to 'print'. Did you
mean print(...)? (envoy.py, line 164) 1) AcuRite
(weewx.drivers.acurite)*
then the standard list of stations
After selecting 0): for the driver the errors arrive:
*driver [4]: 0Traceback (most recent call last): File

hostname or address of the Envoy"
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^SyntaxError: Missing
parentheses in call to 'print'. Did you mean print(...)?*
Before I jump in blindly looking at the code.....a question. Is the core
issue something like the driver no longer will work with the current
version of WeeWx or is there some simple modification that will make it
work?
Stay healthy,
Pat
