What Experts Agree On
What Experts Love
- ✓ Built-in permanent Class A GFCI with a 5 mA trip level meets electric-floor code without a separate GFCI breaker, the only pick here engineered for wet-area radiant floors.
- ✓ Same native Apple HomeKit, Alexa, and Google Home breadth as the baseboard V2, so a tiled bathroom floor joins the same Home app scenes as the rest of the house.
- ✓ Switches up to 3800W at 240V (16 A) and 1900W at 120V, and the included 10K Ohm floor sensor on a 15 ft lead reads actual slab temperature, not just air.
- ✓ Smart Limit Protection caps floor temperature near 86 degrees for sensitive materials, and dual ambient/floor sensing plus 7-day scheduling trims standby heating costs.
Common Criticisms
- ✗ At $199 it is the priciest unit here, and the radiant-floor specialization is overkill for a plain baseboard run where the cheaper Mysa models fit better.
- ✗ Mysa specifies a qualified-electrician install for the line-voltage wiring and embedded floor sensor, so it is the least DIY-friendly pick in the lineup.
