Pros & Cons
Zooz ZEN15 Power Switch (800LR revision)
Pros
- +The only plug here designed for inductive loads — 1 HP against 1/6 HP on a Kasa mini
- +Hardware overload protection cuts the relay at 16.5A sustained, independent of any hub
- +Four measured quantities (W, A, V, kWh) with tunable reporting thresholds — the richest metering in this table
- +Fully local Z-Wave with S2 security; no vendor cloud is in the path at all
- +Cord-mounted design frees both receptacles
Cons
- −Sources conflict on what it is for: retailers market it for 110V AC units and sump pumps, while the 800LR manual's safety list prohibits electric heaters, 220V boilers, 220V pumps/compressors and electrical dryers
- −Needs a Z-Wave hub — the most expensive prerequisite in this comparison
- −Amazon's single long-running ZEN15 listing has carried both the 500-series and the 800LR revision; buy from a Zooz dealer if you specifically need Long Range
- −One device only — the manual explicitly forbids connecting a power strip
- −$37.95 for a single outlet, with a 1-year warranty
Kasa Smart Plug Mini EP25 (EP25P4 4-Pack)
Pros
- +Roughly $8 a plug with real measured energy monitoring — nothing else here is close on price-per-watt-meter
- +Native HomeKit, so Apple users do not need a Matter controller or a Thread border router
- +LAN control means schedules keep running through an internet outage
- +2-year warranty, double the 1 year Wyze, Eve, Emporia and SwitchBot give
Cons
- −1/6 HP motor rating — fine for lamps and fans, not for a compressor, pump or shop vac
- −1,800W resistive means a 1,500W space heater sits at 83% of rating continuously; TP-Link does not endorse heater use
- −No Matter, so it cannot be shared into SmartThings or Google as a Matter device
- −TP-Link's current 4-pack listing title dropped the 'with Energy Monitoring' wording the 2022 launch press release used, and Home Assistant users report the newer hardware revision reports 7-day/30-day totals instead of lifetime kWh
