Please try to fix it via the app 1. In device mode, Edit---Add/Repair keys, find ''power'', click repair, select "filter instructions from could data", then you can test whether other power keys of Denon brand are valid. to confirm the replacement. 2. If the above methods cannot be controlled normally, it is possible that the code of the original power key is correct, but the signal length is insufficient. You can switch X1-Remote to device mode, select the power button on the remote control LCD, and press and hold to test whether it is valid. (long press to send a longer signal) If you press OK for a long time, you can modify it in the app. In device mode, Edit---Macro settings for turn on/off, click the power command and add a duration of 0.5s or 1s. (Note that both turn on and turn off the need to be set. )

Sorry, currently do not support it, if you would like to change the TV, pls kindly create a new activity, tks for your understanding.

Per the long press function, you can create this device as an Activity, and then assign a long press function to the function you want, through edit--assign key for X1-Remote, and use long press and short press to distinguish the function

We have added the device for you, As usual it will take some time then the data will be synchronized with the database。 You can search Brand：Yamaha Model：RX-V863 after 24 hours，pls kindly wait patiently fo it,

Sorry to hear that, X1 deos not support HTTP command control currently, and will pass your feedback to our engineers team , tks for your support.

Sorry, not get similar feedback from other customer, per the issue, pls kindly try the suggestion from other user(mdr55055) and check which factor causes the problem, tks.

The on/off time of some TVs/Receivers is long (maybe 10-20 seconds), but when the activity starts, the default boot time is not delayed, and the next command such as switching the input source will be executed immediately. In this case The switched signal is not received by the TV//Receiver, so it cannot be executed successfully. If this is the case, you can add a power on/off delay command in the APP through device edit----macro settings forturn on/off. Or add the delay command to the boot command in the startup settings of the Activity.

Sorry for the inconvenience, our tech department has added it again, pls kindly try to add it again after 24 hours, tks
