Here’s my take on this.
aeon’s micro dimmers and switches can be used with an ordinary toggle switch as a local control device. This becomes an inexpensive solution.
Having said that, running a dimmer from a toggle is not an intuitive affair, so spousal acceptance factor will be diminished…
Running a switch from a toggle is more intuitive, but you loose the positional state cues (up=on, down=off), and everything behaves like the three ways in your house.
My preference for the micro switch and dimmer local control is to use a momentary push button switch. That way both dimmers and switches work the same way, at least physically and visually.
You can purchase momentary action toggle switches (for garbage disposals) as a control device, however they are expensive for what they are.
In my house I’m using Legrand Adorne switches and plates, I’ve succeeded in converting their standard switch device to a bush button for use as a local control device for the aeon micros…

Hope this helps.
