I'm looking for an exterior wall switch for my dock. At that location is where the power source is located. I would also like to have a remote control for the switch from my house (100ft away) where I can turn the lights on and off. I don't need any fancy Wifi connection to my iPhone. I just need the remote from within the house to be able to turn the dock lights on and off. I also do not need a dimmer. Any suggestions would be grateful! Thank you.
BLH is right, the dual-band devices automatically form a dual-band mesh repeater network.
If you still go with the combo I recommended, you can add the unit Sean suggested for mobile operation. Then your single band remote just has to be in radio range of a dual-band device, then that unit can repeat the signal the longer distance over your power lines.
That also offers the added advantage that you won’t ever misplace a remote control that wires into the house!
