Hello. Welcome to Just Answer.
Are you able to post photos of the box, with all wires shown?
You are most welcome. If I can see the wires in the box, it will likely help greatly in getting everything properly connected.
Great. I'll stand by.
Thank you for posting the photos. It appears there are 3 sets of wires coming into the wall box. Can you confirm this for me?
Thank you for the additional information. It sounds like you've identified each set in the box. If so, please proceed as follows...
The black wire from the panel will feed both devices. So, you need to connect it to each device. It goes to the black or gold screw on the GFI outlet's "LINE" terminals. All 3 white wires splice to each other, and there will be a short piece of white wire from that splice to the silver screw on the GFI outlet's "LINE" terminals. To get constant power into the other device, connect its black lead to the same hot screw on the GFI outlet as the black wire coming from the panel.
That is, assuming the black lead from the occupancy sensor is marked "LINE".
That info isn't shown in the Hubbell device brochure you posted here.
I just found the Hubbell wiring diagram Online, and black IS the hot feed into the device.
Please let me know when you've completed the suggested steps. When you have, there should be two black wires left in the wall box.
Yes, that's correct.
When you have it connected as described, the black wires from the fan and light will be open (not connected to anything), as will the red and blue wires on the sensor. At that point, you can connect the red from the sensor to one open black, and connect the blue from the sensor to the other open black.
That sounds correct. If you haven't already done so, I would go ahead and turn the breaker on and test operation of the GFI outlet and the sensor.
Hmm. Is it possible the sensor was damaged by a previous connection that wasn't quite right? One thing you could check is to make sure all white wires are secure in the bundled splice.
OK. I have seen this in the past, where electronic occupancy sensors won't work without a ground wire properly connected.
I need to sign off now to attend church. I will check for your reply when I return. Thank you.
