Do you mean that the Key bounce or double press? If yes, it could be the firmware of remote control has modified the frequency of signal transmission, we are currently dealing with it, and the subsequent firmware version will fix this problem. You can use the following method to reassign all the physical keys of X1-Remote in Activity by Edit ----Assign keys to macro, and add only one common command in macro

1.Please make sure the HUB is connected to the router, and try to put the HUB close to the router, because when downloading the code base, it is sent from the cell phone to the HUB through the router, and if the network fluctuates, it will cause the card owner. 2. After the card owner, please ask the customer to plug and unplug the power of the HUB again, then re-open the APP, re-add and delete the unsuccessful Device. Any difference?

It is still under certification, pls kindly help us wait patienly for it, if any update, will let you know, tks

Use the app to operate: Me-X1 settings--Firmware update for X1 Remote.  When upgrading, please put the hub and the remote control together to avoid too far to upgrade. too slow to fail

The U1 does not support Activity, although you can use macro for some functions, the U1 does not record power and source status, which may lead to confusing switching. Not sure whether the problem you mention is caused by Activity, if you have Activity requirements, maybe X1 is more suitable for your needs

Sorry, U1 does not support backup settings.
