Good to see the sheets graphing working, but I don't understand why the app can't do the graphing right in it. It's not a lot of data relative to available memory. Even if it plots occasional data, general graphs could be assembled.

Man, I hate having to reading a hydrometer bobbing in my beer. Y'all keep talking this thing up and I'm going to have to bite the bullet!
Set mine up yesterday in a glass of water in the garage, set it to publish to the web.
Looks solid, fluctuates between .998 and 1.002 but the container it's in is kinda small and I did notice it bumping up against the wall which could be throwing it off.
You can check out the log at this link:

FWIW my hydrometer reads .999 in the same water.
Brewing this weekend and can't wait to see how it performs!

Totally, I'd love a nice pretty graph feature built into the app, with a way to export them out to share online.

Do it! I'm pretty happy with mine and can't wait to get the second one.
I don't get it, with things the way are now, the graphs are already online for you to share. In fact, anyone that wants can just view my entire sheet here.
Personally I love the Google Docs integration. Zero down time, zero chance of data loss, and you can configure any sort of graph or metrics you want off of the data.

I wish they'd ship mine! :-(
![Craft A Brew - Safale BE-256 Yeast - Fermentis - Belgian Ale Dry Yeast - For Belgian & Strong Ales - Ingredients for Home Brewing - Beer Making Supplies - [3 Pack]](https://m.media-amazon.com/images/I/51bcKEwQmWL._SL500_.jpg)
It took about 9 days for them to ship mine. They good news is it was shipped priority.
I like the google integration too, especially for raw data collection and archiving. But I'd still like some really shiny pretty graphs available within the app with an easy way to share them out.
Setting up one of the (not that pretty) charts in google is fine, but then exporting that out to be able to share is just extra steps I would rather not deal with.
Seems like it would be a simple add to the app and I think people would find value in being able to look at their device, hit a "graph" button, then a "share" button and post it up here, or wherever in just a few seconds.
My feeling is in between. Graph on the device. If you want it shared, use the current method.
I think there is utility in the graph to make sure your temps are as expected and that the SG has leveled off, indicating fermentation is done and cleanup is taking place. That said, I don't really know who would give a crap about your "fermentation graph". Once you have seen one, you have seen them all, and there is not much utility left. Unless you are in a brew club and are monitoring a batch together, I don't see the point of giving access to others to look.

Count me in for one if you guys do a group buy. I am in Toronto. PM me if it goes forward!
I would be posting the fermentation graphs to my brewday blog that I use to document my brews.
I could see people geeking out on comparing graphs and looking for fermentation patterns for different yeasts / OG / etc... Especially if you had a thread where all the graphs were posted for a particular strain where you could quickly compare a bunch of different fermentations. Maybe it's just me that's into it because I'm a nerd like that.

I would geek out on that too
Of course, having all the data in a Google Doc would make doing so even easier, as you could add all the plot points together and have a single graph showing the various performance across all of your parameters, vs. lots of individual graphs to compare.

I have published a python program that runs on a RaspberryPi (with appropriate Bluetooth 4 dongle) that intercepts the BLE broadcast transmissions and can upload them to a MQTT topic.
It will also work on a regular PC running Linux (it depends on the Linux BlueZ stack).
I am working on supporting publishing to Google Sheets.

I guess I could see the value of comparing curves/attenuation rates for same and different yeasts. Good point!

Very nice, you just saved me a chunk of the weekend! Guess I can cut the grass after all...

Its a no go on the group buy. They can't afford to bring down the price for it. We're just waiting to see if they can bulk package them to save on shipping now.

Purchased. Pulling samples to check gravity is probably my second least favorite thing about brewing.
You can add comments from the app that will populate on the google doc.
I would love if you could input what type of yeast and style is being fermented so we could all compare strain performance. Just sayin...
Hmm... This makes me wonder how easy it would be to modify the brewpi code to log the gravity readings and plot them on the same graph... No need for temperature logging since brewpi already does that, but I guess that might be useful for calibration purposes.

Hi all,
For those of you (like me) having issues with calibration and inaccurate readings the new version of the app (iOS) should hit the app store in 5-10 days apparently. I'm told a major fix will be allowing calibration settings to actually to be stored in the app. Mine keeps losing the calibrated settings currently, rendering it pretty much useless right now.
I got the impression the new android version is already in the wild, haven't confirmed this though.

Just a quick note on their customer service: I had contacted them after my initial test that seemed to reveal a faulty unit, I told them that I would drop it in my fermenter and keep them posted. I received this email from them yesterday:
"David,
Is your Brewometer functioning correctly? I want to make sure you don't have a faulty unit. Please let me know, i can send you a new one if the problem persists. We appreciate any feedback.
Have a great weekend!
Cheers,"
It seems like these guys are willing to back up their product and make it better!

I got mine in last night, it will connect to one phone without an issue, but not the other. So far looks to work great though. I'll try again today to get it connecting to the other phone, let you guys know.

Does the second phone have Bluetooth 4.0?
How off could the temp or SG be? If it's just a basic offset, just do the math in your head. Don't see how that's useless. Yes the app should keep the calibration but this isn't a deal breaker IMO.

Nope, I ended up using a different phone this AM after figuring that out. I have it reporting to a spreadsheet now as well. It just jump about some, having gone from 1.007 to 1.009 and temp looks a solid 3-4f higher than it is. I probably just need to calibrate.

I'm a strong supporter of the product, and have had very productive communication with the team behind it. I'm not writing it off, I just have no idea how the app was written, i don't even know whether the app does temperature compensation for gravity. So i would be speculating at actual readings by doing the math in my head, as you put it. My readings are way off, by the way. 5 to 10 degrees F and up to 10 gravity points.
I wish this thing would just connect to a network and upload on its own and by pass the whole need a extra phone or tablet to generate continuous logging.
