CM907 looks like a replacement possibility and gives us the

Hi Matthew,
Can't help you with other options, but here is a similar discussion about 3 weeks ago. You must only connect two of the wires, *not* Neutral! If you decide to follow the steps in my closing posting on that thread, note that I am really a DIY newbie and may have messed up; proceed at own risk.
