Weather hat rain total

Support

Hi,

After cleaning out a spider egg case, I’m getting readings from the rain sensor.

I watched the rain_mm_total.total() grow and then it went down and would eventually go up (raining through the whole time) - using averaging.py example.

I created a test version av.py:

(pimoroni) pi@weather:~/weatherhat-python/examples $ diff av.py averaging.py
5d4
< import datetime
68,69d66
< with open (“/tmp/readings”, “a”) as f :
< print(f"{datetime.datetime.now():%Y-%m-%d %H:%M:%S} rain total: {rain_mm_total.total():0.2f} mm", file=f)
71c68
< time.sleep(5.0)

time.sleep(5.0)

\ No newline at end of file

The results in /tmp/reading:2025-02-01 15:19:12 rain total: 0.00 mm

Using chat gpt’s suggestion I found a history_depth=1200 in class History - 1200 * 5 second interval makes 100 minutes.
