Hi there,
This is a high/low schematic for a whole house fan.
I’m looking for a wifi-switch that will switch 230V to 115V for high/low speed, but can’t seem to find any. (if there is…?)
Any ideas/suggestions?
I had a similar 2 speed attic fan. I used 2 individual wire in / inline switches and had code to make sure only one was on at a time. I was using Insteon in line switches for this application and it was USA 120VAC.
The point is you could consider 2 individual inline switches and automations that always turn the other one off and then turn the desired one on.
