Yeah, I noticed that too. I’ve conditioned myself to do as you suggest, full refresh the page to get accurate readings. My issue was definitely the first reading from the Tilt. The temp. was 999F and gravity was 20 points lower than actual gravity. Deleting that data point from the graph fixed...

I think simply deleting that first erroneous Tilt reading fixed the issue. As soon as I deleted it, the Attenuation reading was correct. And it wasn't immediate, but the ABV reading eventually corrected after deleting that data point, probably within a minute or two. That seems to fall in line...

Disregard below! I deleted that first data point from the Tilt and that fixed the attenuation reading. ABV is still negative though. - - - Where are you seeing that?? The very first data point sent from the Tilt showed a temp of 999°F and OG of 1.040. No idea where those values came from but...

Thanks for the quick reply Yooper! I went back and looked at the recipe and the only thing that I noticed was under the Yeast section, the Custom Attenuation field was set at 0%. I don't know if this is normal, I don't recall ever editing that field but regardless, I changed it to 75%. I also...

Sorry if this has been covered elsewhere, I couldn't find anything... I'm brewing my second or third batch with the Tilt integration but for some reason, the graph on the Fermentation tab is showing a negative ABV value: The OG on this particular batch came out much lower than expected...

Bummer. Looks like a fermentation calendar has not yet been added. That's about the only thing I miss about iBrewMaster.
