wunderground - no data validation

[bbrendon]

Hass 0.50.2

I found this in the database stored for my pws_temp_f entity while I was researching data reliability issues from wunderground (value based). I wasn't expecting to find a string where there is usually (should only be) float.

 <function WUCurrentConditionsSensorConfig.__init__.<locals>.<lambda> at 0x7f0d6a20d6a8>

| sensor.pws_temp_f | <function WUCurrentConditionsSensorConfig.__init__.<locals>.<lambda> at 0x7f0d6a20d6a8> | 2017-08-02 11:37:41 | 2017-08-02 11:37:41 |

Where I would expect something like:
| sensor.pws_temp_f | 96.4   | 2017-08-02 22:12:50 | 2017-08-02 22:12:50 |
| sensor.pws_temp_f | 95.0   | 2017-08-02 22:18:00 | 2017-08-02 22:18:00 |

It appears wunderground sensor doesn't make sure its storing a float in the database. It just dumps whatever.

Currently running 0.52.1 and seeing the same behavior. Wundergound sensor just throws whatever the API gives it:

EDIT - A restart fixes the issue. For what it's worth, this is the first time I've ever noticed this problem. I am seeing a similar problem in the logs after restart, but the sensor data (that I use, anyways) looks OK right now.

I am also seeing these in Wunderground. This looks relevant in the logs:
