mijia smart home

hi i have the xiaomi mijia 2018 (SXJ02ZM ) and it records fine to sd card but the upload to mi cloud seems buggy it only uploads a few seconds and then stops uploading for several minutes so lets say i have 10 minutes of continuos movement in front of the camera and set to record upon motion...

Hi. I bought mijia temperature sensor and mijia control hub 2 . I can not connect sensor to hub (sensor to phone application mihome connects normally). I have only these devices in "add device" tab . I tried to choose other types of sensors but with no luck. Can anyone help me with this?
