The absolute bane of my existence in every automation project is three-way dimmers. Perhaps it's my particular brand of anal but I absolutely HATE state switches with three-ways because I want down to always be off and up to always be on. Combine that with the level of brightness indicated not remaining (or ever getting) in sync. I've tried a variety of solutions most recently my disastrous and expensive journey into Innovelli and never had success. I can already hear you now saying "you need Caseta". Yes, except Caseta has two IMHO huge flaws. Flaw number 1) I can't set a default brightness level. Grrrrrrr. I don't want the lights always coming on at full. Nor do I want to always ramp to my level. I like what I like and I want on to mean 34% (or something like that). "Just do it programmatically." Sure, but this always leads to flaw 2) the debounce algorithm stops that from being a pleasant experience. It adds significant delay.
It blows my mind that this still hasn't been solved. I understand the issues with power drain and specs not really supporting this with the existing protocols. But then I thought "wait -- low power draw... mesh... people might just be able to solve this now." So.... what do people think? Are we on the edge of having synced, three-way dimmers now that thread is coming?
