I couldn’t find much information about this device so I figured I’d start a discussion thread for it starting with some initial info from my brief time with it.

Model: SQR44102WHZ

Notable Features:

  • Power and Energy monitoring for both outlets (combined)
  • On/Off for one outlet
  • Z-Wave Plus (S2)

Overall this plug seems like a solid option to add energy monitoring at the outlet level. The power reporting is almost instant which is useful for triggering automatons based on power draw. The power reporting doesn’t seem to “chatty” either. After initially powering a device it doesn’t seem to report another level until until a significant change in watts. I don’t currently have a way to test what the reporting threshold is. I would prefer if there was an option to set the threshold for reporting like some other devices have.

The energy monitoring seems to be accurate when testing with a pigtail plugged into a Kill-a-Watt monitor. Both outlets contribute to the energy readings. The outlet itself draws about 0.7w with no additional load.

I was able to find these for under $20 USD on Amazon and at that price I don’t think there is a cheaper option from a reputable manufacturer to get energy monitoring to all your devices.

EDIT

While looking into this device further I found a thread reporting that the energy monitoring only works while the ON/OFF switch is ON meaning that if you had a device plugged into the always on outlet and switched the controlled outlet off you would no longer get energy reporting. I confirmed this behavior which is a bit of a bummer for an otherwise solid device.

So I’ve been installing these over past few days and I have to say that these receptacles really are great for the price. Z-wave devices usually come at a premium price because of the licensing/certifications that come along with the protocol but these just dont seem to carry that.

I don’t know why seemingly all controlled receptacles have one uncontrolled outlet. If I want to control my house, I want to control everything in it. Anyway, just installed one of these. The zwave inclusion process seemed to take several minutes, but it worked. I was confused why the uncontrolled outlet wasn’t hot to my AC tester. Turns out you have to actually plug something in first. At least that was my experience. Maybe part of the “tamper-proof” design? I also was bummed to find the metering doesn’t work when the controlled outlet is off.
