Power GeniusXL Remote power

I use Wemo mini, it less than $20 now

also, relay

and, junction box

Whole project cost around $50, if you would like to make it yourself.

I build one and using it for the last 5 month without any issue, Ican turn ON/OFF PGXL from my phome or iPAD on WEMO application. You can find description here, scroll to the bottom

Good luck in your decision

Your example seems expensive and still needs 240 VAC wiring, and locks you into the Sonoff smart switch.

I built my own:

Contractor, with 120VAC coil. :

Installed in this box:

I use these to **** the box:

On the 240 VAC side, I used a 3-foot, 240, 15 amp extension cord, cut in half and wired into the relay, inside the box:

I used a 10-foot length 240 VAC 15-amp extension, of the same as above, to run from my 240 VAC, 15 amp wall plug to the relay box.

I used this cord to run from the relay box to the PG-XL: (other amps may vary)

I cut off the female end of an unused 110VAC cord, and wired to the relay coil. Plug the 110 VAC into your smart switch of choice

I applied this label to the box:
