THIRDREALITY ZigBee Smart Plug 4 Pack with Real-time Energy Monitoring,15A Outlet, Zigbee Repeater,ETL Certified,ZigBee Hub Required,Work with Home Assistant,Compatible Echo Devices and SmartThings

I have been so impressed with the quality and reliability of these plugs, that I now have five of them in use. Their firmware has been updated regularly, and I have recently updated mine to v1.00.98, dated September 8th, 2025. Contrary to other reviews that mention no support for power restore settings, these are the second generation models with power monitoring, and their power state upon power failure restoration can be set to "on", "off" or "previous state".My Zigbee Plus mesh network covers a 2400 sq. ft. two story home, and these plugs also act as Zigbee mesh repeaters, strengthening the overall performance of the network. Signal quality (LQI) ranges from 200-255. Two plugs are compact enough to fit into one duplex outlet. ETL certification is important for electrical and fire safety.The plugs are fully compatible with my home automation system that runs on HomeSeer V4, and HS4 uses the same outstanding Zigbee2MQTT front end as Home Assistant (HA). My system also runs a Z-Wave Plus mesh network, and whereas each protocol has its advantage, Zigbee Plus has advanced to the point where it is easier to setup, and it's cheaper than Z-Wave Plus.My plugs reliably and quickly control lamps, space heaters, an instant hot water heater, and other small electronics.

Running 1500+W trhough these, space heater on one, air dryer/convection oven on another, and two plugged into computers as I was curious wrt wall power draw, which is where I get my 'eyeball' accuracy from...They stay connected to a hubitat elevation well enough to use as do their temp/humidity sensors which I used to rig up a trivial space heater on/off in the winter for a room... sonoff did not fare well at all and I gave up on that sonoiff after wasting some time faffing around with it, and always having that temp/humid sensor go offline permanently until kicked in the rear manually again...er, Im getting offtopic, but these plug meters also survived the catastrophic failure of an electric grill last summer, which happened while I was OOS of the grill... grill plug got a bit melty, smart plugs nada, it still works like a champ, no signs of any any overcurrent or anything of the sort unlike the grill, although presumably that was all internal to the grill but still the plug wasn't affected(so was it plug elec or grill elecs preserving, which I doubt since grill plug got a bit melty and Imma guessing smart plug cut power...)I have seen the smart plug rep close to 1700W(once when it was new) on the air fryer/convection oven thing, but normally on high power usage settings(fryer, high 'baking temps, generally high temps) its more around 1550W which jives...)[EDIT January 25, 2025]I had the smart plug that I had on my primary desktop fail last night while doing an update on OpenSUSE Tumbleweed after 20d. There were 3346 packages that needed to update.Packages ALL updated fine, and install started as usual.Unfortunately right as it got to c. 20 packages left to update the plug decided to flake out and started randomly turning off and on, leaving me with a broken update, which was not a problem, as it appears that the BTRFS snapshot is saving the day(re-running update right now minus the smartplug only 2800 packages yet to go(rust))I plugged that borked smart plug into an outlet earlier today and it is still exhibiting randomly turning off and on in short enough intervals to be noticeable...Plug was paired w/a hubitat elevation hub, providing power monitoring and simple on/off wireless plug control, nothing complex.Hubitat will be going away at some point this year when I rebuild my primary server and have home assistant running...I wish that the plugs were easier to open(haven't tried as they are obviously not offering easy access for good reasons, but I can help but wonder flakey fuse or some other component in the plug, but Ill mark it bad and toss it somewhere for now... maybe later break it open and see what the guts are like and check the components... manual switch seems to be fine clicking the button, doesn't seem to stick or anything and nothing rattling around inside, which is all I can do w/o cracking it open at this time..., and I do not really feel entirely q7ualified to crack it open and 'fix' it which I probably could simply because soldering skills and well depending upon mfg process and reasons[/EDIT].

I have a total of six of these plugs now (4 basic, two with power monitoring) in my home. To be brief, I'm very satisfied with these so far.The four basic plugs act mostly as repeaters to help extend my mesh from my Home Assistant Pi in the front of the house to the boiler room in the back of the house (one floor down in the basement). With one plug in each room, with various amounts of obstructions between them, each maintains healthy LQIs to each other and to the sensors connected to them (above 60 in all cases, reaching 150 when they have an unobstructed LOS in one case). Honestly I could probably remove a plug or two without impacting the network's stability, but I'd rather have the peace of mind. One slight downside that I noticed was from one plug that had nothing plugged into it; if the plug was on but there was no load, it would make a buzzing noise. Turning it off stopped the noise, so I did that. I'm not sure if this happens with a load plugged in.The two energy monitoring plugs are connected to our washing machine and gas dryer (which both use standard 120v power cables). Each plug measures the following values, as described in Home Assistant while using ZHA:- AC frequency (Hz)- Power/active power (W)- Power factor (%, may show as Unknown or not show up at all)- Current/RMS current (A)- Voltage/RMS voltage (V)- Summation delivered (kWh, which appears to be cumulative over time)The readings appear to be generally sensitive at the lower end of the scale. Both machines are registered as pulling 1-2W when off and about 4W at idle, which allowed me to set up a threshold helper in HA that lets me know when the machine is on or off. I think the update frequency is somewhere on the order of 15-30 seconds, but I'm not entirely sure. For my purposes, it's more than fast enough.All plugs work perfectly when using ZHA. The pairing process was painless, all plugs support power on configuration, you can set up OTA firmware updates in ZHA with a config change, and it supports channel migration, so if you change your Zigbee network to use another channel they'll automatically update without needing to re-pair.All in all I'm quite satisfied with all of these plugs, especially at their current prices of 4 basic for $30 and one power monitoring for $12.UPDATE 2024/1/10: I recently had to re-set up my Home Assistant install, and both of the power monitoring plugs I owned before no longer show the nonfunctional Power Factor stat. This might have been disabled at some point in the past on ZHA's side, as the labels for each stat had been changed. I've updated the list above to reflect the new labels.Additionally, I picked up another power monitoring plug recently when they were on sale recently, and this new one has Power Factor both in the list and functioning. EDIT 2024/1/30: After some diagnostics, I've determined all three PM plugs are running the same firmware revision (0x10013048, or v72 if you convert the last three numbers from hex to decimal), but the older two don't show the power factor. This suggests to me there might have been a minor hardware revision to reenable that properly, so if you're looking to write automations or analytics that use it, be sure to check the plugs beforehand. Beyond that, all power monitoring plugs work identically.
