    Customers are satisfied with the performance of the precision measuring sensor. They mention that it works well with a GE Z-Wave Wireless Lighting Control, and has been working solidly for over a year. The contacts work great, and the setup works perfect. The sensor is heavy, with spade and screw terminals that work well. Overall, most are happy with their purchase and recommend it to others.

    Solid solution for remotely controlling hot water heater
    5 Stars
    Solid solution for remotely controlling hot water heater
    Excellent solution to remotely control (and use an automatic schedule) an electric 240V hot water heater with an added benefit of now having a manual switch at the heater. Even better is the cheap solution only cost $16 for the contactor, a recuperated power cord, and a salvaged electrical enclosure (this one from a well water pump starter). You could just add a switch (or pull the plug) if you don't need the smart control (this one is a $21 YoLink however there are many others available). Unlike some other reviews, this unit has a solid click when engaged, no chatter, and absolutely no steady-state hum or buzz. Unlike some other similar products' comments, this one is truly a 2 pole. Easy to wire, the 120V goes to the side spades (neutral/hot wires can be connected on either side), however I would suggest using the lugs and not the spades for your 240V load as most applications would be high current.

    5.0 out of 5 stars Works as it should.
    Reviewed in the United States on July 13, 2020
    I used this to build a smart water heater timer/controller. I had an older mechanical water heater timer, that had failed after many years of reliable use. I wanted to add a smart controller to this, but there does not seem to be one that is ready made for this purpose. I decided to try one of these smart relay switches to control a contactor which controls the power to the water heater. I installed the smart relay switch, a 220v 40a contactor w/110v coil, and a terminal strip into the same box the old mechanical timer was in, and it works like a charm. Now I can add timers using the smart app, and also use voice control with my Amazon echo to turn the water off and on. It would be nice if someone made one of these complete and ready to install. But it's nice that I could build this for under $35. That's about half of what the mechanical timer would have cost to replace, and not I have smart control of it.
