I have an outdoor light controlled by a wireless Lutron switch (upstairs), the base unit is in my basement (picture attached). The upstairs switch does not work anymore. The basement unit is in a difficult to access utility closet. The red LED flashes and the basement switch does work.

Can anyone identify the model or do I have to remove the upstairs or downstairs plate(s)? Or can anyone tell me how to get the upstairs switch paired with the basement unit?

Thanks
