Temperature Measurement Update Threshold Too High

[JoshMcguigan]

The problem

I was debugging what seemed to be issues getting updates from a SNZB-02D temperature sensor when I found this thread. It turns out the issue is caused by the large temperature measurement update threshold (set to 0.5 deg c). This is configured in Home Assistant Core here:

https://github.com/home-assistant/core/blob/ab68a26000017ae845dbd1900e4d6ce450baaf4a/homeassistant/components/zha/core/cluster_handlers/measurement.py#L145-L151

I've confirmed that updating this value from 50 (representing 0.5 deg c I believe) to 5 (representing 0.1-ish deg f), and then re-configuring my sensors, I get much more accurate temperature data.

I'm happy to make a PR if this is an acceptable change. Thank you!

The reporting threshold isn't a static 0.5C: the sensor also sends an update every couple of minutes as well.

From what I remember, these Sonoff sensors do not themselves respect the attribute reporting configuration very well. Can you upload a debug log of the sensor operating for an hour with the original config?
