Operation
RAPT Pill Hydrometer & Thermometer - Operation Guide
Setup and Testing
After charging, assembly and device registration your RAPT Pill should be calibrated before use. Refer to the Calibration section for instructions on how to calibrate your device.
Calibrate and then assemble your RAPT Pill. After calibration confirm your RAPT Pill is correctly sending telemetry to the RAPT Portal by leaving it in a jug of water or sugar solution for an hour and checking to see if telemetry has been received by the RAPT Portal. It is best to conduct this test in the position where the Pill will be located during fermentation. For example, f you are fermenting in a fermentation chamber place the Pill in a jug in the fermentation chamber to confirm that telemetry is received and your RAPT Pill has good signal strength.
Once it is confirmed that your RAPT Pill is sending telemetry then sanitise your RAPT Pill with an approved sanitiser such as StellarSan or Phosphoric Acid which has been correctly diluted according to the instructions on the sanitiser’s container.
Drop your RAPT Pill into your fermenter to monitor the specific gravity and temperature of your brew in real time
Sleep Mode
The RAPT Pill will enter sleep mode when the device is in a horizontal orientation. It will automatically wake up when its orientation is changed indicated by the illumination of a green light on the circuit board. When not in use ensure the RAPT Pill is in a horizontal orientation to ensure it remains asleep.
When in normal operation the Pill will stay in sleep mode but will 'wake' at the set telemtry interval to send telemetry. This will be visually indicated by the green LED illuminating briefly.
Updating Firmware
Your RAPT Pill will automatically check and install for firmware updates when plugged in to USB power with a USB-C cable (not supplied).
To check the firmware on your Pill, plug the Pill in with a USB-C cable (or place it on the charging base if using the Wireless Charging Kit) then open the Pill Captive Portal by connecting to the Access Point on your phone or tablet or through the Pill IP address.
Plug your Pill in to USB power with a USB-C cable (or place it on the charging base if using the Wireless Charging Kit)
Connect to the Pill Captive Portal with your phone or tablet or through the Pill IP address.
Navigate to the Diagnostics page.
Check that your RAPT Pill is running the latest firmware.
If a firmware update is available, this will be updated automatically when the Pill is plugged in to USB with a USB-C cable (not supplied) or placed on the Wireless Charger (purchased separately).
To check and update manually in the event that this is not up to date, select Check for new firmware. Your device will automatically download and update the most current available firmware.
Complete Wireless Charging Kit
Use of the KL31936 Complete Wireless Charging Kit with the RAPT Pill is very useful for increasing ease of use and minimising the need to calibrate the Pill after charging, updating firmware etc.
Once the Complete Wireless Charging Kit or the KL32452 Barebones Wireless Charging Kit (Coil and Weights only) has been correctly installed (please refer to this video for an installation guide) then the Pill can be wirelessly charged. You can also purchase the KL35910 Pre-assembled Wirelessly Charged RAPT Pill
Wireless charging also allows for updating the firmware and accessing the Pill Captive Portal without needing to open the Pill housing to plug the Pill into USB-C.
To charge the Pill simply place it on the wireless charging base, ensuring that the coils are centred over the indicated charging spot on the base. When the Pill is placed on the base the red LED will illuminate to indicate that the Pill is charging. The green LED will start flashing indicating that the Pill is broadcasting a signal so that you can connect to the RAPT Pill XXXX WiFi to open the Captive Portal.
The RAPT Pill will periodically check for OTA (Over The Air) firmware updates when charging commences, so this is typically all that is required to ensure that your firmware stays up to date
Sessions
When the RAPT PIll Hydrometer has been registered to the RAPT Portal, you can create a custom Pill Hydrometer Profile in the RAPT Portal.
A Pill Hydrometer Profile allows you to receive alerts from the RAPT Pill based on telemtery data.
Pill Hydrometer Profiles are a way to set up Alerts based on the telemetry recevied 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.
You can set an alert when:
The temperature reaches {a specified temperature} - select the operator Less Than or Greater Than and Input a Temperature 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 gravity velocity is greater/less than the specified valuereaches {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
To receive alerts on your mobile device, you must have the Google Play or Apple App Store app installed.
In order to receive alerts you need to select Enable Mobile App (Push) Notifications in the My Account settings in the RAPT Portal. You must also enable notifications for the Google Play or App Store App on your mobile device.
