    Measuring rainfall in inches?

    I'm hoping I missed something obvious here.

    I'm running HS2 with MCSTemperature...it has been working fine with outdoor weather station, and I decided to add on a 1-wire rain gauge that I had in my misc parts bin. It has a 6-inch bowl, so it takes about 400 ml of water to make an inch of measurable rain.

    When I pour in an inch of "rain", the tipping bucket increments the status (count) by 36.

    My first place to start scaling was the mcsTemperature startup screen, in the Devices/Files tab. Moving down to the Rain Count Calibration field, I set a count of 0.028 (1/36th of a gallon per click), and a rate of 1. This seems to get me graphs in the ballpark of reality, although the unit of measure is still "gallons". I assume I could so something similar for the rainfall rate.

    This seems to be kind of a roundabout route for measuring rainfall and rate of rainfall. Is there a cleaner way to a solution? I've googled around, read the docs, and haven't found anything obvious.

    Many thanks.

    If you select your rain bucket counter to Todays Rainfall type of sensor then the units displayed should be in inches. If it set to be a water flow counter then it will show in gallons.

    The "standard" domestic rainbucket is 0.01 inches/count. The calibration approach you used appears to be correct to allow mcsTemperature recognize that your count corresponds to something other than 0.01 inches.

      Thanks

      Many thanks...that did it. I'm a little suspicious of the magnet/sensor placing, since it counts as the bucket tips in one direction, and not in the other.
