This pill hydrometer already has been pre-assembled with wireless charging coil already integrated.
Simply use this device with any QI Certified charger.
The RAPT Pill allows accurate and precise, true real-time specific gravity and temperature logging and control via wifi/bluetooth integration with the RAPT Fermentation Chamber or RAPT Temperature Controller, RAPT mobile app or RAPT IOT.
The RAPT Pill acts as both a real-time gravity testing hydrometer and thermometer allowing instant gravity and temperature measurements and also logging from inside your fermenter during fermentation.
The RAPT Pill boasts many advantages over other wireless hydrometers and thermometers including tough design, better ergonomics, sanitary design and less susceptible to error as a result of hops, krausen or CO2 bubbles generated from fermentation.
IMPORTANT NOTE:
Ensure the RAPT Pill is charged for at least 24 hours before use. This is to ensure that it is fully charged and the battery is callibrated. You will not be able to access the Pill Captive Portal if the battery is insufficiently charged.
Once the RAPT Pill is connected via USB-C and connected to wifi, the firmware will automatically update to the current version (if needed). The Pill must be plugged in via USB-C and connected to WiFi in order to receive firmware updates. A 2.4gHz network is required.

BLUETOOTH BRIDGE
Although the Pill Hydrometer will work in wifi mode the optimal solution is to use the Pill in bluetooth mode as this has several advantages including:
1. Bluetooth is more power efficient so it saves battery life. This enables the Pill to save battery by only using power efficient as it's only giving out low energy Bluetooth beacons but then the bridge device that is connected to mains power is doing the heavy lifting and transferring that data to the RAPT web portal. This is by far the most reliable way to use the Pill Hydrometer.
2. Bluetooth signal is better at penetrating through the fermenter more easily especially if you have a stainless steel fermenter or fermenter inside a fridge or fermentation chamber.
3. Bluetooth bridge mode allows you to use the Pill Hydrometer as the temperature probe to get a core fermenter temperature without the need for a thermowell. The onboard Pill Temperature sensor is also very accurate as it's an onboard digital sensor with no flexible cable. (please not if you have just charged or been in AP mode excessive heat from the battery does effect temperatures readings so wait 30min after charging for the battery temp to reach equilibrium)
4: Bluetooth connectivity allows for powerful fermentation control with the ability to use gravity and gravity acceleration to set automatic and accurate fermentation control.
To take advantage of the Bluetooth bridge mode you will need to pair the RAPT Pill to either a RAPT fermentation chamber (KL15813) or a RAPT Temperature Controller (KL22927).
Please watch the youtube video on how to do this.
LONG BATTERY LIFE
The RAPT Pill has a long battery life and can last 5 months between charges when utilising Wifi. If only using Bluetooth the battery can last 2+ years before needing to be recharged. The RAPT Pill has a USB-C charging port on the circuit board allowing fast charging from any USB-C cable.
Pill Housing Design
The RAPT Pill housing boasts many advantages compared to other wireless hydrometers such as:
Different housing colours are sold separately on the website allowing customisation of your RAPT Pill. The colours available include:
What is RAPT?
The RAPT IOT Hub is a free service whereby any RAPT enabled product can both log and store data to the hub where you can conveniently access this data. The RAPT hub can also allow you to control your devices remotely giving you absolute control of the device irrespective of where you are. The RAPT portal enables you to make complex temperature profiles that involve different temperature settings over time meaning you can start/run a temp profile giving you a set and forget experience. The RAPT portal also controls the alert/notification process for you so you can receive email notification in the off instance that something doesn't go to plan.
There is no limit to the number of RAPT devices you can connect the RAPT IOT Hub. This is in contrast to other popular wireless hydrometers where you are limited by the number of hydrometers you can connect to an app.
Please note: The RAPT Pill is fully wifi and Bluetooth capable. Bluetooth integration requires a compatible RAPT Bluetooth enabled device such as a RAPT Fermentation Chamber or RAPT Temperature Controller
SPECIFICATIONS
*Accuracy: +/- 0.002 SG points
Temperature Range: -20C(-4F) and up to 60C(140F)
Pressure: 0-5bar
Battery: Li-Ion 18650 (we use the EVE Brand)
Size: 37mm Diameter x 125mm Long
Temperature Accuracy: +/- 0.2C (0.36F)
*Accuracy will be affected if solids are stuck to the outside of the pill hydrometer. If you gently shake the fermenter from time to time this generally helps to wash hops and solid chunks of krausen off the body of the Pill and through the fermentation these will generally drop to the bottom of the fermenter.

"This was my first RAPT purchase but will not be my last. The visibility of the Gravity graduation and abilty to perfectly time the diacetyl rest. has given me some great results. Temp controller will be next purchase or will it a second Pill?"
"Great bit of kit, being able to just check how a fermentation is going while out of the house is a massive peace of mind, when calibrated properly I've found it to be highly accurate. A very easy purchase if you are wanting to upgrade your brewing process."
"Brilliant bit of kit Follow online instructions and it is amazing Get the wireless one to save you hassle of recalibrating after every charge Linked to my rapt temp controller and love it"
"Got this floating around in a batch right now. Easy to set up and use and I’m not great with technology. Would definitely recommend it"
"the RAPT app & website have poor performance/uptime so the RAPT Pill can become useless when you go to use it"
"Great bit of kit. Pros: once running, amazing information about your ferment. Cons: a bit fiddly to setup first time. Instructions are ok for the main set up, but not great for the pre-setup. Took me a while to realise the wifi pill still had blockers on the battery that you need to remove. Also the housing comes “90” tightened. As a first time user, I had expected the wireless version to come with no need to undo it. Would be good to have those basic instructions come in the box. So - on first set up - open the pill, remove the battery blocker at the terminals, and tighten it up until the final seal is right up to the plastic. Charge for 24 hours then follow the instructions online. From there, you’re good."
"Awesome unit. Who doesn't love a graph! Really handy being able to monitor your ferment from the couch. Also nice not having to open it up to charge. There is a plastic tab that disconnects the battery when it's new. Don't be a dunce like me and leave it in and wonder why it's not working properly 🤦"
"I have previously been using the tilt but now I’m a convert. Pair the pill to the rapt temperature controller and you’re on a winner. The app is so easy to read and changes can be made on the fly remotely. Never going back"
"What a game changer, no more running to check on things, just open the app and everything you need to monitor is there. The wireless charging works a treat too! I may need to get another for the tool kit!"
"Easy peasy once charged and registered. Bond with the Fermentation chamber is awesome. Ordering a second one asap."
