Might be worth powering off everything but the repeater and just one lighting circuit that was known NOT to pair as a test. See if the repeater and the troublesome device can pair. If they do then power up other circuits until you get problems again. Could be time-consuming to debug. You could use a PC running AirSpy with a RTLSDR (usb-connected Software Defined Radio) to scan frequency ranges. Watch the bands as you turn circuits on/off.
