The short version: King Electric is a US electric-heat manufacturer (making smart heating solutions since 1958, per its own materials) with two current Wi-Fi line-voltage thermostat families: the Hoot series (K901/K902) and the ATMOZ series. Both are genuinely confirmed smart products, sold on Amazon and Lowe’s with real model numbers, unlike some other niche electric-heat brands in this category. We could not find independent star-rating reviews or forum threads specifically evaluating reliability, but King’s own published troubleshooting page lists known issues (unresponsive touchscreen, Wi-Fi connectivity problems, inaccurate temperature readings), which is useful signal even coming straight from the manufacturer.

Who It’s For

King Electric thermostats are built for 120/208/240V electric baseboard and wall-heater circuits. The Hoot and ATMOZ lines are a fit if you want Wi-Fi scheduling and remote app control on baseboard heat and prefer an established heating-hardware manufacturer over a general smart-home brand retrofitting into this category. It’s most relevant in the Northeast and other electric-baseboard-heavy regions where King Electric is already a common heater brand.

Design & Build

The Hoot series comes in single-pole (K901, 3-wire) and double-pole (K902, 4-wire) configurations, in white or black, supporting 120/208/240V circuits. The ATMOZ series is a separate double-pole 240V, 16-amp Wi-Fi line. Both use a touchscreen interface. We don’t have independent build-quality assessments, but King’s own troubleshooting documentation acknowledging touchscreen responsiveness issues suggests this is a real, if not universal, complaint worth watching for after purchase.

Setup & Compatibility

These are direct baseboard/wall-heater circuit replacements: no C-wire, no separate hub, standard line-voltage wiring matched to single-pole or double-pole configuration. Confirm which wire configuration (3-wire single-pole vs. 4-wire double-pole) matches your existing heater setup before ordering, since Hoot and ATMOZ models aren’t interchangeable across pole types. King’s own site provides model-specific installation guides.

App & Ecosystem

The Hoot app and ATMOZ app both advertise 7-day scheduling and remote temperature control from a smartphone. King’s own marketing claims up to 28% heating cost savings versus economy thermostats, using more accurate temperature sensing to reduce swings, a manufacturer claim we can’t independently verify and would treat as a ceiling rather than a typical result. We found no confirmed Alexa, Google Assistant, or Matter integration for either line; if voice control matters to you, verify current app-store listings before buying, since smart-home integrations change over time.

King’s own Hoot Wi-Fi support and troubleshooting page lists several known issues customers have run into: unresponsive touchscreen, brightness/display problems, an overly loud confirmation beep, Wi-Fi connectivity drops, and inaccurate temperature readings. That a manufacturer maintains a dedicated troubleshooting page for these specific symptoms suggests they’re common enough to document, which is worth weighing even without independent review data to back it up.

Price & Value

King Electric Hoot / ATMOZ
Price (USD) $60–$110
Retailers Amazon.com, Lowe’s, electrical supply houses
Voice assistant support Not confirmed

Competitively priced against Cadet’s non-connected TEP Series and below Mysa, reflecting a narrower feature set (no confirmed voice assistant integration) in exchange for genuine Wi-Fi app control at a lower price point.

Pros & Cons

Pros:
– Confirmed, currently sold Wi-Fi thermostat models (Hoot K901/K902, ATMOZ) with real retail listings, unlike several other niche electric-heat brands
– Established electric-heat manufacturer since 1958
– Available through mainstream channels (Amazon, Lowe’s)
– Manufacturer publishes a dedicated troubleshooting page, a sign of active product support

Cons:
– No independent star-rating reviews or forum feedback found to verify real-world reliability
– Manufacturer’s own troubleshooting documentation lists touchscreen responsiveness, Wi-Fi connectivity, and temperature-accuracy issues as known symptoms
– No confirmed Alexa, Google Assistant, or Matter integration
– The 28% savings claim is unverified manufacturer marketing, not an independently tested figure

The Recommendation

Buy King Electric’s Hoot or ATMOZ if you want confirmed Wi-Fi scheduling on baseboard heat at a lower price than Mysa and don’t need voice assistant integration. Match the pole configuration (single vs. double) to your existing wiring before ordering.

Consider Mysa instead if Alexa/Google/HomeKit integration matters, or if you want a thermostat with a deeper independent review trail.

Frequently Asked Questions

What’s the difference between King Electric’s Hoot and ATMOZ lines?
Hoot comes in single-pole (K901) and double-pole (K902) configurations across 120/208/240V. ATMOZ is a separate double-pole 240V, 16-amp Wi-Fi line. Confirm the specific model’s wiring and voltage rating against your heater before buying.

Does King Electric’s Hoot thermostat work with Alexa or Google Assistant?
Not confirmed. We found no evidence of voice assistant integration for either the Hoot or ATMOZ lines; check the current app listing before buying if this matters to you.

Is the King Electric Hoot thermostat reliable?
We don’t have independent review data to confirm this either way. King’s own troubleshooting page documents known issues with touchscreen responsiveness, Wi-Fi connectivity, and temperature accuracy, worth being aware of, though a documented troubleshooting page isn’t the same as a confirmed high failure rate.

Does King Electric’s thermostat qualify for utility rebates?
Not confirmed. Check your state or utility’s qualifying list before assuming eligibility. See Smart Thermostat Rebate by State.
