Re: Troubleshooting Question

And what's even weirder, is the diodes that worked, when I checked them in reverse polarity, the voltage kept climbing on my meter until it said OL ... whereas the bad diodes gave me nothing when I...

Re: "Smart" light switches and correct wiring...

I just found the answer to number 1. Apparently, the point of the neutral wire is to ensure that the WiFi circuit remains powered even when the switch is in the off position.

Re: Swapping out a NiMh for a LiPo?
