Thermostat only reports rounded temperature #28

Closed mkfink closed 6 years ago

mkfink commented 6 years ago

When reporting the temperature measured by the bmp280 over mqtt, the value is almost always rounded to the nearest whole number but then with two decimals of precision. For example, it only reports 25.00, 25.00, ..., 26.00, ... etc.

Oh yeah cause evan only wanted to display whole numbers on the display and then I used that for the reporting.

It sometimes still reports out decimal fractions from halves to fifths, i.e 25.33, 24.80, etc. That suggests there might be something amiss. Will that cause any overflows?

I'm seeing stuff like .4 and .62. I'm not worrying.
