tnx bro
im sory about your crystal ball
frind thats messege after update ( exit status 1
'struct' has no member named 'SWITCH_1')

i feel the code from bigining is error
i had make alot of change on it
please can make afull code
i connect the 2 relay on pin 10 and 11

Replace RemoteXY.switch with your own variable, my crystal ball is broken so I can't see what variable name you used...

Maybe need to invert logic, depending if your relays are Active LOW or Active HIGH.

hi ...
I have 2 channel relay modle .. i put in 4 and 5 pin
in normaly 2 switch control it

i need to control it with one switsch .. means if switsh off turn relay number one on
and number 2 off , and if switch on turn number one off and turn the number 2 relay
