Decimals ? #3

Closed jhagberg closed 8 years ago

jhagberg commented 8 years ago

Hej In the emview app there is watt with decimals and counters with decimals. for example 3700,1 W

But in this app there is only integers with no decimals. Is this by design or can we improve this?

I am working on an daemon that can push data to a Emoncms installation. Got sort of a working one that push imported power as a feed called house_power.

Then I notice that it is only integers.

Aha easy fix Just ad decimals to the division pregard=hex2dec(smainfoasci[64:72])/10.0 pregardcounter=hex2dec(smainfoasci[80:96])/3600000.0

I can fix a pull req later
