Friday I was shooting furniture inside a sun room, with my Zeus 2500 just outside the window. Einstein inside the house with me as fill. All firing from my CC on camera.
Approximately 90% misfires on the Zeus outside. I finally resorted to optical slave which left me with only manual power control.
Any thoughts?

What material was the sun room made of? Specifically, was metal siding between the CC and the CSR+ receiver? This can attenuate the signal. Also, as the Zeus pack between the receiver and the CC?
