I have an old 1930s house with a three way connection that seems to match what was shown here: (How common is the line at the fixture for 3-ways?)
Using an innoveli red series gen2 dimmer with a ge aux switch I tried to wire into the configuration suggested here: (LZW31-SN 3way Non-Neutral - Line/Load Separate Boxes)
The configuration generally works, but the aux switch cannot turn the light on. If already on the aux switch can be used to turn off the light, but not on. Is this a result of having the line voltage at the neutral connection on the aux switch? Is there another way to make this arrangement work?
By the way, I don’t see this configuration in the supplied wiring diagrams, but understand it to be a common wiring for older homes.
Thanks in advance!
