I see it. It is firmware 1.35.
The load is a chandelier. I would need to get details from my mother-in-law.
I’m no longer in the house to open it back up. The wiring is very old, so it is a little hard to understand.
Previously I needed a little help on doing my first dimmer 3 way, in the same gang box (3 way, no neutral, possible bulb issues, unresponsive switch!). Now I am doing the left dimmer switch in the same box. As you can see, it is a mess and took me some time to clarify the setup. My testing indicated that for this 3-way setup, line was coming up to the first floor with a bundle of wires going up to the second floor switch. In that gang box there was another bundle for the fixture wiring. This is why I wired it per: https://desk.zoho.com/DocsDisplay?zgId=691830694&mode=inline&blockId=k4wwh437a820318ff497da86f135e3829acb6
My big question: I would think if it was wired incorrectly it would be pretty obvious. The fact that it works fine under ‘Load Only’ and not ‘3 Way Momentary’ is puzzling…especially the behavior I indicated. I was wondering if anyone has shown a similar behavior. I tested this with 2 different dimmers (both bought at the same time) and 2 different AUX switches - both bought at different times.
