Sorry, the problem with RUKU maybe caused by remote firmware which modifies the frequency of signal , we are currently working on it, and the problem will be fixed in the subsequent firmware version . Temporarily you can use the following method to reassign all physical keys of X1-Remote in Activity by Edit----Assign keys to macro and add only one common command in macro. or pls kindly send a email to sofabaton@outlook.com, then we can send a picture to you for reference
