There is another electronic hydrometer on the way called the Hydrom, it can stream but is it posible to get it incorporated.

I use the Guten system and I have 6.5 Litres under the grain tun, when I do the water calcs this currently means I have to add this my strike water and take it from my spare amount to get my water figures. This works when I remember but is it all that hard to include this in the next update.

When setting up with raspberry pi do you Start logging to Tilt Pi, or as the help doc shows have this function turned off
