Here’s the tactic I’m having a run at.
One aeon dimmer/or switch module, works 3, 4 or n way.
Does require momentary action switches and a relay.
I found this bad boy for the relay:
120vac SSR
I did read somewhere that the aeon switch (and also the dimmer) were supposed to allow 120vac as a trigger input. Yea, well I toasted a dimmer trying that, hence the relay…
