Smart Plugs / Zooz
Zooz ZEN15 Power Switch (800LR revision)
The one to buy for a sump pump or dehumidifier — and it needs a Z-Wave hub.
Overall score 8.1/10
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
Zooz ZEN15 Power Switch (800LR revision) review: what the specs say
The one to buy for a sump pump or dehumidifier — and it needs a Z-Wave hub. At $37.95, Zooz's 2017 model sits in the middle of the range — the smart Plugs we compare run from $11.99 to $52.99. It scores 8.1/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Load Headroom at 9.5/10 — how much of the nameplate 15A you can actually use continuously, and what the plug is rated to do with motors, compressors and heaters — the spec buyers most often get caught by. The weakest is Ecosystem Support at 5.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: 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; and needs a Z-Wave hub — the most expensive prerequisite in this comparison. Every specification on this page comes from Zooz's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.
