## What is PLAATO?

PLAATO is a reinvented airlock that monitors your ongoing fermentation, sending the key parameters directly to your phone.
PLAATO lets you:
- Monitor the fermentation activity
- Measure the ambient temperature [°F/°C]
- Estimate the Specific gravity and alcohol content [°Oe, %w/w]

PLAATO features:

● WiFi-connection - Access and share your data from wherever you are, using the PLAATO-app.
● Versatile - Works on beer, cider, wine and all other alcoholic fermentations.
● Replaces your ordinary airlock - Simply switch to PLAATO, and monitoring will
start
● Real time access to data - During the fermentation, you have access to the
essential parameters in real-time, giving you an unique insight of how different strains of yeast work, how temperature affects the rate of fermentation and much more.
● Export data - Understand the unique data generated from each batch, and use the information to compare techniques and taste, and increase you understanding of whats going on.

How PLAATO works
Plaato measures continously the flow of CO2 from the fermenter, and knows at any time the total amount of CO2 that has been generated by the fermentation.
Since the fermentation process generates equal amount of CO2 and ethanol, Plaato can use this data to estimate the Specific Gravity (SG), alcohol percentage and quantify the fermentation activity.

### 1/5 — Plato airlock and iOS

*2023-02-20*

Doesn’t work; will not pair with network. Briefly connected and counted 13 bubbles and no connection after that in spite of vigorous fermentation. Impossible to re set-up with message that network could not communicate with device.

### 2/5 — update SG

*2022-04-20*

I’ve been using this for several months and it’s not yet “learning” much despite that mode being set. 
so what do I get? optimal is good data, but since that isn’t there yet, at least a nice graph as I manually update the SG would be nice. so if you could improve things such that when I take a manual reading (which it turns out is still very necessary/making this device a bit pointless in my experience thus far) the least that you could do is smooth out that fermentation line on the graph with the new data instead of having this hard jump when I update what the device/app thinks is going on vs. reality

### 4/5 — Good but...

*2021-05-23*

I just got the Plaato for my kegerator, and am planning to add a second one. I really like how easy it is to pair everything, and setup was super simple.  My big disappointment is with the app. I’m planning to mount an iPad with that is paired to my kegerator on the wall, so friends and visitors can see what’s on tap. However the current app is not responsive to the tablet screen, and will not rotate horizontally. Super disappointing!!

### 1/5 — Doesn’t work

*2021-02-02*

Not even a monitoring gravity level

### 4/5 — Using with Plaato Keg

*2021-01-27*

First if this is a really nice tool for monitoring the levels in my keg.  The notifications work and are not overloading me with notifications.  

Where it could be better...  the temp function has issues and yes the company has a work around to change the settings, but it does not work well in my setup. I can never get it to an accurate reading.  It to be honest, I did not buy this to keep up with my temp.  So this dose not impact my review in any way.  The only reason I give it 4 stars instead of 5, is that I really don’t care how many gallons I have left in my keg.  Well, not really. If they could make that field selectable, pints would be better in my opinion.  99% of the time I pour into a pint glass, and after a few I don’t want to have to worry with math!  What would I rather see?  You have 3 gallons remaining?  No,  tell me instead in have 24 pints remaining.  That is more helpful to me.  Please give us the option here to select how we view beer remaining!

### 4/5 — Good, but a few bugs to fix & features to add

*2020-07-02*

First, using this with the PLAATO Keg (which is pretty great), not the airlock. 

Pairing is easy enough if you’ve ever use any other IoT/connected device.
App design is sleek and mostly intuitive and easy to navigate.  I agree with the reviewer TJ$$ before that it would be nice to have some better tracking of averages, month over month use, etc. The graph now (of temp, volume, and pours) over time is useful, but doesn’t list days, or give ability to see usage/month etc. I’m sure it’s something that can be added at some point.
Only real issue I’m having now is the notifications stopped coming through my phone.  I’ve double checked iPhone notification settings, and to be sure, uninstalled and reinstalled the app.  Still not getting the notifications.
Either way, solid app to go with cool keg monitoring.  I know it’s a small firm so I’m excited to see them grow and continue to add features and fix bugs.  Overall, it’s a great start, keep pushing forward PLAATO team.

### 1/5 — Constantly loses connection to airlock, can’t add device to wifi, can’t reset it

*2020-06-20*

I’m on my second airlock now after the first broke due to poor build quality. Over the time I’ve had the second airlock I think it’s maybe worked about 3 out of 20 brews. The app keeps dropping the airlock and just says it’s offline. The app doesn’t help you set it up well at all as it just asks you to make sure your airlock is in “setup mode” but doesn’t tell you how to get it in setup mode. I can never see my airlock on WiFi to connect with it (yes I’m using 2.4GHz). The app does not help you reset the device and even using the help documentation I’ve not been able to reset it to retry adding the device again. The app doesn’t send you any notifications about fermentation which would be helpful. I don’t know, I’ve not successfully used it in months. 
Biggest waste of time and money I’ve experienced with brewing, and I’ve had to pour two batches down the drain in the past but they don’t even compare. I envy anyone who has been able to use the PLAATO airlock consistently every brew without problems.

### 5/5 — Fantastic little gadget

*2020-03-06, version 1.2*

5 star for the airlock

### 4/5 — Good design; a bit buggy

*2019-12-22*

I give this app 4 stars bc it’s a great design but still has some bugs to work out with PLAATO keg. Mine keeps reverting back to metric units and changes my max keg weight - so I have to constantly redo my settings. I hope that in future release the notifications will also be in “US Standard” when set up that way. I’d also like to see a better way to see how much beer is poured (total) based on day, week, month, etc. And would be awesome to see it tracked over time, comparing month to month - similar to exercise apps. Hey, drinking beer is one form of exercise.

### 3/5 — Apple Watch

*2019-05-05, version 1.1*

Please make apple  watch friendly
