I used an old PC with windows 95 and a script to an apc 8 outlet controller to control some homemade solenoids to power my 220v 1000w ballasts. Worked like a charm after I figured out how to get everything running.

My problem was the 15 amp circuits, so I had to build the solenoids, buying prebuilt was too expensive for me...

Never saw any 20 amp smart outlets.

I built a contactor panel using contactors similar to these http://www.amazon.com/Packard-C240A-Contactor-Pole-Voltage/dp/B008GVSKU2/ref=sr_1_2?ie=UTF8&qid=1457040915&sr=8-2&keywords=contactor. ////////I just noticed this particular contactor is for 24v, using the normal digital plug in timers, you would need contactors that close when 120 is applied.


Right now all my lighting is controlled with one basic wall timer, it sure beats trying to sync up 4-5 different timers. The timer can be linked to several contactors. So no worries about high amperage melting a 15A timer. Also have my environment controls set up the same way.
I am building a master time clock out of an arduino to control everything based on the exact conditions of the room and also time. The parts are super cheap.. A controller custom to my needs can be made for 40 bux in parts and a crash course in coding, I went to school for electrical engineering and have been working as an electrician for years.

Got this yesterday. Rated for 1500 watts. Took a while to get it setup.
Its got a lot of potential. gonna try it with fan first. It can run a schedule, would be nice if i can write a batch file and add or subtract a few minutes each day, start my seed chamber with 8 hours dark then add a few minutes each day until theyre in sync with veg chamber. With 1 on each light i can simulate sunrise, that might save some electric. I can coordinate my exhaust and CO2. A lot of potential. Gotta see if it holds a program when theres a power outage or loses connection. Just one for now.
$30 at home depot.

I now own 4 of these and im gonna pick up a few more. I had a hard time setting and testing them up, but finally got help from service rep.
I wouldnt trust them with the lights yet, but nice for controlling climate and environment.
Looking forward to purchasing http://www.amazon.com/Wimoto-CLI001...rue&ref_=ox_sc_act_image_1&smid=ATVPDKIKX0DER

Not available yet.... I practically invented this fucking thing. LOL
