I think you not need to use send query command to read relay state. Because every time if controlled by wall switch panel or wireless remoter will auto feedback command "Feedback:RELAY-KEY-255,x,1,OK （x is the channel of Relay）"
another relay feedback commands are :
RELAY-SET-255,x,1,OK (Turn ON Relay x successed) this is turn on/off one relay's feedback
RELAY-SET_ALL-255,D3,D2,D1,D0,OK this is turn on/off all relays' feedback.
You just have to analyze these commands for relay state update.
relay controller's input port is for alarm sensor use, not for manual control.
