I recently upgraded to the latest firmware on my OP2, installed a new VRC0P and updated PC Access. Since doing so, I have has several issues with zwave. Lights are not turning off as programmed. Example, arming the system at night usually shuts off a lot of lights, but when I get up in the morning, they are still on. The controller states they are off. Do you think this is a zwave network, VRC0P, or OP2 firmware issue? Also, can I load an old firmware back in? Thanks. SJ
