Dave,
First off hats off to a super plugin. I your plugin to control lights and shortly to control blinds on a sunny side of the house.
My question has to do with what seems are phantom calls to the Weather Underground API. I have only one Wunderground Plugin device , but I am getting about twice the calls that I would expect. I set the interval to 5 minutes and exceeded the limit of 500, in about 21 hours! I disabled the plugin and had no API calls during that time. If I change the interval to 10 minutes I am able to get through the day (not exceeding the 500), but the API count is about twice what it should be (I am counting the Current Conditions - Observation Time changes).
What am I overlooking?
Thanks
