1.Product AdaptationAdapt to DECENT coffee machine, Beanconqueror APP and DEESPRESSO APP, etc. In addition to this, we also have the Bluetooth open source protocol https://github.com/BooKooCode/OpenSource, which allows users to transmit data to their own data source or application.2. Freezing, jamming problems / charging indicator does not show when charging / grams drift, inaccurateReason :Firmware version is not the latest versionMethod:After power on and leave it for one day to consume power completely, firstly upgrade the latest firmware in BOOKOO APP (if it doesn't work, then upgrade the latest firmware in BOOKOO Tools App (attached at the bottom of this page, also can click :https://bookoocoffee.com/wp-content/uploads/2025/02/Bookoo-Tools-usage-paper.png)), after updating, the problem still exists, please contact us.2.1 Some of the grams drift Reason : the transparent strip on the bottom of the mini scale didn't come offMethod:Just tear out and throw away and scale will get normal working.3.Air bubbles under the protective filmReason: The protective film on the surface of the panel is to protect the surface of the scale from scratches, dust, etc. during production, quality control and transport. In the transport process may produce individual bubbles, this bubble does not affect the use and after-sales.Method:It is recommended to tear off.4.BOOKOO App did not synchronize weight data4.1 Non-Bluetooth Function ProblemReason : The firmware may not be updated or the device does not support the use of BOOKOO App.Method:Firstly record a video to assist engineers to identify the cause, and then answer the following questions：① Whether the firmware version is the latest② Mobile phone brand and model③Can you have weight data by using Beanconqueror APP④Whether the same situation occurs when using the app with other mobile phones or tablets.4.2 Bluetooth Function ProblemsReason: Whether there is consent in the privacy policy pop-up window when using BOOKOO App (attached picture), if there is no consent, the related functions of Bluetooth API (including device discovery, device pairing, data transmission, etc.) can not be used.Method:Uninstall BOOKOO App and re-download it, find BOOKOO APP in the settings of your mobile phone, tick the box to allow access to the Bluetooth function, and go back to the APP to agree to the privacy policy pop-up box request. Contact us if the problem still exists, attach photos/videos if you can to assist with troubleshooting.5. Automatic shutdown5.1 Automatic shutdown due to software failureReason :The "auto shutdown" refers to the black screen without shutdown animation, which belongs to the software failure of version 1.0.8, our engineers said that version 1.0.9 can greatly reduce the frequency of triggering.Method:Update the firmware to the latest version, if the problem still exists, contact us and attach photos/videos if possible to assist in troubleshooting.5.2 Auto shutdown after no operationThe scale will automatically switch off by default after 15 minutes of no operation and no weight change.6.The device name of the scale is not searched in the Bluetooth connectionProblem Cause: Users should be in the mobile phone system Bluetooth connection, but our mini scale is connected through BOOKOO APP.Method:After opening the Bluetooth, click on the mini scale icon, the connectable devices will appear in the home page.7. APP Bluetooth auto-disconnectIf you switch to another APP in the middle of the process, the Bluetooth will be disconnected automatically. 8.Battery ReplacementCurrently does not support self-replacement of the battery, if it is damaged during the warranty period, you can contact the official free repair. Battery life is 5-7 years, normal use will not be damaged.9.Provide product improvement suggestionsYou can join our Discord group https://discord.com/invite/ebFWFAFmYn and feedback to the engineers, thank you for your comments, and then you can pay attention to our version of the update.

1. Product adaptation - Compatible Coffee Weigher: BOOKOO SCALE-mini, Acaia lunar, Felicita ARC - Compatible devices (direct plug): Flair58, coffee devices with G1/8 threads - Compatible devices (requires m6 adapter kit): Lelit v3, Rocket R58, Profitec Pro 400, 500, 600, 700 ECM Puristika, Mechanika, Synchronika and other devices with E61 brewing head - Others: devices with pressure gauges can be used in principle, but it is recommended to operate the modification under the guidance of professionals, the BOOKOO team is not responsible for the modification behavior(The list of compatible coffee machine devices is constantly being updated)2. Bluetooth not connecting Download BOOKOO Tools APP to upgrade to the latest firmware version, after upgrading, we suggest you turn off the automatic connection in BOOKOO App setting page, and then reconnect EM with BOOKOO APP manually.3. Data reading errors, non-synchronous Whether the firmware is the latest version, usually restart the APP first and then reconnect the EM manually, if the problem still exists then please contact us.4. Installation issues Normally, our EM is mounted on the short side of the tee that has the BK symbol.5. Tee orientation issues Because the thread is not the same problem, so if you tighten it, the orientation may not be the same, so in order to solve this problem, we designed the O-ring and seal to achieve the O-ring and seal to achieve the O-ring and seal to achieve the O-ring does not need to be screwed particularly tightly, after tightening to regulate the position of the table, such as screwing a little bit looser to come over the table after the table to the right on the line, so that the leakage will not occur.6. Problems with importing visualization files Our APP currently does not support importing curve information from visualizer, we will take this requirement into consideration later, thank you for your feedback.7. When in use, there is water leakage at the connection with the coffee machinePlease remove the tee and check if the large washer at the threads has come off. If it is the red O-ring that has come off, there is a replacement O-ring in the supplied kit. If none of the above, please contact us.

1. How many pounds of impact pressure is the powder hammer PuckGo is an impact tamper with a constant impact force of 15kg (about 33lbs).Feel light because, we independently developed a vertical separation of the impact of the patented structure, our energy storage locking structure and the firing pin is working independently, and the impact surface is a larger area of the ring surface, spring force into the actual impact of high efficiency and low loss, the impact is more balanced and uniform, because the more dispersed and uniform so the feeling will be lighter, but in fact, the pressure is able to tamping powder cake.2. Hidden powder some serious We thickened the pressure of the foundation to reduce the hidden powder, but the impact of the powder tamper can not be avoided or there will be some hidden powder, this may require daily cleaning, with a small brush brush can be, put the position of the cloth powder needle directly inverted over the hidden powder can also be poured out.3. Foundation hammer can be replaced by other models? Currently can not, other functionality have not planned to come out at present.
