# Pill Hydrometer Profiles

### Create Pill Hydrometer Profile Session with Alerts

To create a **Pill Hydrometer Profile**, Click the **Add Profile** button in the top left.

Then, select a **Profile Type**: **Fermentation**

Next, select a **Name** for your Profile (such as Belgian Dubbel)

Enter a **Description** for your Profile - this can be anything and is just intended for your reference.

**Pill Hydrometer Profiles** are different to other RAPT Profiles as RAPT Pill Hydrometers are purely measurement instruments.

**Pill Hydrometer Profiles are a way to set up Alerts based on the telemetry received from the Pill.**

This is extremely useful, especially if you are not using the Pill Hydrometer in conjunction with another RAPT device.

RAPT Pill Hydrometers will measure **temperature**, **gravity** and **gravity velocity** (rate of change of gravity over a specified interval).

You can set up alerts based on any of these.

For example, you can set an alert for when the gravity drops to (for example) 1.025 at which point you may wish to raise the fermentation temperature for a diacetyl rest.

You can set an alert for the gravity velocity to drop to 0, at which point fermentation is likely finished and you can begin a cold crash.

Click the **Add** button <img src="/files/QXAiZD3b1ZvxtKaG4Qxs" alt="" data-size="line"> to add a Alert

This will bring up a new dialog box which allows you to select and enter the desired alert details.

### Start Profile Session without Alerts (Logging Only)

If you just wish to record telemetry over a set interval and do not need any alerts (if not doing a dry hop, for example) then a Pill Hydrometer Profile Session can be started directly from the Dashboard of the RAPT Portal.

In the RAPT Portal, select the Pill you wish to begin a Profile Session on.&#x20;

Press the Play Button <img src="https://docs.rapt.io/~gitbook/image?url=https%3A%2F%2F570278281-files.gitbook.io%2F%7E%2Ffiles%2Fv0%2Fb%2Fgitbook-x-prod.appspot.com%2Fo%2Fspaces%252FUqN4sW0x2s4yh6iiT8NN%252Fuploads%252FiCwWNkLtk5PJj5hzWhel%252FPlay%2520Stop.png%3Falt%3Dmedia%26token%3D395278bd-1578-4e3d-9701-a73435f2faf4&#x26;width=300&#x26;dpr=4&#x26;quality=100&#x26;sign=6e94a212&#x26;sv=2" alt="" data-size="line"> to begin a profile session. **NOTE**: If the Play button is not visible a Profile Session may already be running. Select the Stop button first.

This will open a dropdown menu

**Device**: You can select the RAPT Pill Hydrometer or RAPT Bluetooth Thermometer from this menu

**Profile**: This is a **Logging Only** Profile Session with no alerts. To create a Profile with Alerts, select the **Create Profile** option

**Name**: You can enter a name for the Profile Session. This is useful as all sessions are saved in the Profile History so a name makes it much easier to identify each Session

**Start Date**: You may select a Date and Time to begin the Profile Session. This is extremely useful as often telemetry is not received immediately after placing the Pill in the fermenter (for examlpe). You may choose a time an hour or two after pitching yeast and putting the Pill in the fermenter to ensure that the first received telemetry in the Profile Session is up to date and accurate

### **Alerts**

**Alerts** allows you to set up a custom alert for each step. You can add as many **Alerts** for each step as desired. You can select when to send the alert and also enter a custom **Alert** message (such as "Add Boil Hops Now")

You can set an alert when:

* **The gravity velocity is greater/less than the specified value reaches {a specified temperature}** - select the operator **Less Than** or **Greater Than** and Input a Gravity Velocity (in points per day, where one Point = 0.001 sg) and Alert Message

* **The gravity reaches {a specified gravity}** - select the operator **Less Than** or **Greater Than** and Input a Specific Gravity and Alert Message

* **The temperature reaches {a specified temperature}** - select the operator **Less Than** or **Greater Than** and Input a Temperature and Alert Message

<mark style="color:red;">**To receive alerts on your mobile device, you must have the**</mark> [<mark style="color:red;">**Google Play**</mark> ](https://play.google.com/store/search?q=rapt\&c=apps)<mark style="color:red;">**or**</mark> [<mark style="color:red;">**Apple App Store**</mark> ](https://apps.apple.com/th/app/rapt/id1573192994)<mark style="color:red;">**app installed.**</mark>

In order to receive alerts you need to select **Enable Mobile App (Push) Notifications** in the My Account settings. You must also enable notifications for the Google Play or App Store App on your mobile device.

Once you are happy that all the **Alerts** are correct, make sure you hit the **Save** <img src="/files/sbMytZMNRJgV75d1z8uR" alt="" data-size="line"> button to save the profile to your **My Profiles** library. You can then send it directly to your RAPT device using the **Send Profile to Device** button <img src="/files/db6BXxBCWRzIR8M6kkAm" alt="" data-size="line"> or using the **Play** <img src="/files/897aBF99YHaL9VthHWvh" alt="" data-size="line"> button in the **Dashboard** to start a new profile!

**Congratulations! You have made a Pill Hydrometer profile and are ready to brew!**

### **Sample Profile (with Alerts)**

There are many reasons to have Alerts generated during fermentation. As the Pill can measure Temperature, Gravity and also Gravity Velocity it is super easy to set up triggers for Alerts at various important stages of fermentation.

For example, during a fairly standard fermentation you may wish to be notified when the Gravity Velocity has dropped to the point that it is desirable to start increasing fermentation temperature.

An alert to add dry hops can be added at any point.

An alert to check fermentation is done (or notify when it is finished using Gravity Velocity) is very useful.&#x20;

Using Pill Hydrometer Profile Sessions you can essentially set a custom alert to be notified at any point during fermentation, greatly improving the ease of fermentation
