Third Reality Smart Wall Outlet ZW1 Review: Reliable Zigbee Metering in a Bulky Body
The ZW1 is an in-wall Type B duplex outlet whose two sockets are switched and metered separately, and owners who run it on Home Assistant through ZHA or Zigbee2MQTT describe a smooth pairing, working per-socket energy readings and a dependable Zigbee link that also helps the mesh. The recurring complaint is the hardware: the body is large and deep, the wire terminals use small set screws, and the faceplate does not always sit flush. It is a strong pick for a Zigbee household with roomy boxes, and a poor one for shallow, older or double-gang boxes.
- Home Assistant and Zigbee households
- Per-device energy monitoring
- Replacing two smart plugs with one outlet
- Extending a Zigbee mesh
Pros
- Two receptacles switched completely independently
- Separate energy monitoring for each socket, reported as working well
- Easy Zigbee pairing with Home Assistant via ZHA or Zigbee2MQTT
- Acts as a Zigbee router, extending the mesh
- Works with SmartThings hubs and the SmartThings Station
- Configurable power-on behaviour after an outage
- Manual button per socket and child-proof shutters
Cons
- Large 48 mm deep body that needs a big single-gang box and is tight to wire
- Does not fit a standard dual-gang box, and may not sit flush with screwless cover plates
- Small set-screw wire terminals that owners worry about stripping or losing
- Requires a Zigbee hub and does nothing standalone
- Apple Home and Google Home need the Smart Bridge MZ1, sold separately
- No direct Matter support
- Load ratings and protection features are not published
Who is the Third Reality Smart Wall Outlet ZW1 for?
It suits someone who already runs a Zigbee network and wants smart control built into the wall instead of plugged into it. The two receptacles are independent, each with its own manual button and its own energy reading, which fits a spot where two different things share one outlet, such as an entertainment center on one socket and a home office on the other. Owners using it with Home Assistant, Homey or SmartThings-style Zigbee hubs are the happiest group. Anyone who needs it to match screwless decorator plates, or who is retrofitting an older, smaller box, should read the caveats below first.
What owners like about the ZW1
Setup is the first thing people praise: the Zigbee 3.0 connection to Home Assistant, through ZHA or Zigbee2MQTT, went through without trouble for the owners who tried it, and the devices keep working reliably afterward. The per-socket energy monitoring is the second theme. Owners say both sockets report usage well, and one found it useful for spotting which device was drawing more power than expected once an entertainment center and an office setup were split across the two sockets. Because the outlet is always powered it also acts as a Zigbee router, and one owner who needed to push a signal toward a detached garage found it much stronger than the plug-in units previously used in the same spot. One owner pairs it through an Echo-based Zigbee bridge and builds routines in Alexa, while noting that it does not behave well through the native app over Matter, which fits the spec sheet: the outlet has no direct Matter support.
What to know before you buy
Almost every critical review is about size and wiring, not about the radio. The body measures 114 x 69.7 x 48 mm and owners say it only fits a large single-gang box, will not go into a standard dual-gang box, and leaves almost no room for coiled wire behind it. Several had to trim wires, add box extenders or even replace the box, and one reports it took repeated attempts to seat the outlet. The wires clamp under very small set screws that owners fear can strip or get lost, and some say the outlet does not sit flush with screwless decorator cover plates. One owner finds the status lights too bright and could not turn them off, although the spec sheet lists an adjustable LED brightness, and the manual buttons sit vertically on the side, spreading the sockets apart. The rated load figures are not published. A Zigbee hub is required, and Apple Home and Google Home are reached only through Third Reality's Smart Bridge MZ1. Plan the wiring work or hire an electrician.
Is the Third Reality Smart Wall Outlet ZW1 worth it?
For a Zigbee-first household with a roomy box, yes: it replaces two smart plugs with one invisible outlet that meters each socket and strengthens the mesh. The mixed average rating reflects the installation experience rather than the electronics, since the same owners who criticise the housing still say the Zigbee side works well. If your box is shallow, old or crowded, or you care about a flush faceplate, measure the box before ordering and expect some wiring effort.
Frequently asked questions
Does the Third Reality Smart Wall Outlet ZW1 need a hub?
Yes. It connects over Zigbee only and needs a hub, such as Home Assistant with ZHA or Zigbee2MQTT, a SmartThings hub or Station, Aeotec, or Third Reality's own Hub or Smart Bridge.
Can the two outlets be controlled separately?
Yes. The upper and lower receptacles are independent: each can be switched remotely and automated on its own, each has its own manual button, and each reports its own energy use.
Will it fit my existing electrical box?
Check before you buy. The outlet measures 114 x 69.7 x 48 mm and owners report it only fits a large single-gang box, leaves little room for the wires and does not go into a standard dual-gang box. Several needed box extenders or a new box.
Does it work with Apple Home, Google Home or Alexa?
Apple Home and Google Home need Third Reality's Smart Bridge MZ1, sold separately. Alexa works through a Zigbee hub that bridges to it, such as SmartThings or Aeotec. Matter is not supported directly.
Does it work as a Zigbee repeater?
Yes. Because it is permanently powered it acts as a Zigbee router, and an owner who used it to carry the signal toward a detached garage reports a much stronger link than from the plug-in units used before.
