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 (attached picture).


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 machine
Please 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.
