Have replied your question via email, pls kindly check.

Pls kindly tell us specific model of your sony device at first, tks

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.

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 version upgrade. Per the issue, 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,

About Xfinity , if there is something wrong with the key response which could be caused by the frequency and length of the signal. we will update the firmware to fix the problem later.

Some remotes have four color keys, their function is related to the device you added. If your original remote doesn't have four color keys which means they are not assigned, you need to assign a normal command or macro command to it (Activity mode can assign macro command)
