Lutron makes the L3T251
which is a combination dimmer and timer for a bathroom fan and light combo in a single range switch.
It does not require a neutral wire because it pulls power from the light circuit, but as a result, I have to use an incandescent bulb in it. LED bulbs don't provide a low current resistive path for the parasitic power draw. I've tested this and if I put a known good LED bulb in, the switch is dead.
Now that incandescent bulbs have been banned, what are my options. If there's a similar product out there that uses a neutral and works with LED, I haven't found it. I imagine you could make a parallel high resistance circuit that would provide power to the switch when the light is off, but I have not found anything like that.
Any suggestions?
Big damn.heros, ain't we just
