We have been suffering from missed finishes more and more often. I believe it is due to a weak signal between our photocell and WTN. When both units are indoors we have 3 bars(strongest you can get) but once photocell leaves our building it drops to 1 bar. Also it seems that this issue has become worse over the past few years, starting out with just a couple missed finishes to last week with way too many. Our plan of attack is to try and run wires through wall and outside of window and place our WTN against the building outdoors. Does anyone have ideas on how to get s stronger signal between these two devices or had similar issues?
