RC Raceway

Hi,

I'd like to be able to turn the outside lights at the barn on and off from inside the house (as well as from the barn, as they work now). There's good wifi signal in both places, the distance is about 150 ft. I've got power available at both switch locations with a neutral in each box. Both locations are fed from the same panel, though there is a subpanel in the barn. Running additional wires to the barn is impractical.

So far I've only confused myself reading about various home automation and remote devices at a wide range of price points.

I'd prefer something that just looks and works like an ordinary on/off three way light switch-- I don't want to have to go find my phone to turn the lights off, I don't need to program it or dim it.

Any thoughts as to a good, relatively cheap solution?

Please help.
Thanks!

I didn't find the right solution from the Internet.
