Many weather sensors just report a cumulative rainfall amount to their display unit. That is, when installed the sensor will start with 0 millimeters, and then as rain falls, it will just keep adding to that number, until the sensor loses power, or is reset.

Since it took me a long time to reach a working solution, I am posting this information to save people looking for the same hours and hours of fruitless searching, and frustrating experimentation.

While experimenting with the pywapi I found a few problems that require an article, in case someone is facing the same issues.

First, for Canadian cities, you need a more current version of pywapi. On Ubuntu 12.04, the python-pywapi is 0.2.2-1 and does not have the API for Weather.com. The version on 14.04 is 0.3.6, and does have that API.

If choice results in confusing the adopters, increasing the
cost for developers, and fragmenting the market, resulting in less adoption, then it is not a good
thing.
