The short version: The TQX is made by Lux Products, an established American thermostat brand (also behind the Kono and Geo-WH lines) rather than a rotating marketplace seller — a meaningful difference from most products in this batch. It’s a newer Matter-native thermostat with millimeter-wave occupancy sensing and support for up to five remote sensors. It launched recently enough that we could not find professional, hands-on reviews (Wirecutter/RTINGS-style testing) or Reddit buyer threads yet — just the manufacturer’s own materials and SEO listicle summaries.

Who It’s For

Buyers who want a Matter-compatible thermostat with room-sensor support and don’t mind being an early adopter of a newer product line. Because it bridges occupancy, temperature, and humidity data into the Matter ecosystem, it’s a reasonable pick if you’re building out a Matter-based smart home and want your thermostat to participate rather than sit in its own silo.

Setup & Compatibility

Lux specifies C-wire and wall plates included, and lists compatibility with standard 24VAC forced-air systems. The included sensor and up to four additional remote sensors (sold separately or in bundles) use millimeter-wave occupancy detection rather than simple PIR motion sensing, with coin-cell batteries rated for roughly two years and ±1°F temperature accuracy.

App & Ecosystem

The TQX supports Alexa, Google Assistant, and Apple HomeKit natively, and functions as a Matter bridge — sharing occupancy, temperature, and humidity data with other Matter-compatible devices (lighting, security, etc.), which is a more open approach than most closed single-brand ecosystems. We found manufacturer and SEO-listicle claims of “significant energy savings” and “responsive occupancy sensing,” but no independent, hands-on test we could verify — treat those specific claims as marketing until third-party testing catches up with this newer product.

As an established brand product (unlike most in this batch), the TQX has a somewhat better chance of eventual ENERGY STAR or rebate-list inclusion, but we found no confirmation of either as of this writing. See Smart Thermostat Rebate by State and verify current eligibility before assuming a rebate applies.

Pros & Cons

Pros:
– Made by Lux Products, an established thermostat brand with a real support and warranty history — unlike most products in this batch
– Native Matter, Alexa, Google Assistant, and Apple HomeKit support
– Millimeter-wave occupancy sensing is a genuine step up from basic PIR sensors
– Supports up to five remote sensors

Cons:
– No independent professional reviews or verified buyer feedback found yet — it’s new enough that testing hasn’t caught up
– Remote sensors likely cost extra beyond the base unit — confirm what’s included in your specific listing
– Marketing claims about energy savings and sensing accuracy are unverified by third parties as of this review

The Recommendation

The TQX is worth considering if you want Matter and multi-sensor support from a brand with actual staying power, even though independent reviews haven’t caught up with this newer release yet. If you’d rather buy something with a longer independent review track record at a similar price, compare it against ecobee Enhanced or the Amazon Smart Thermostat.

Frequently Asked Questions

Is TQX a generic marketplace brand like the others in this price range?
No — TQX is made by Lux Products, an established American thermostat manufacturer also behind the Kono and Geo-WH lines. That gives it a more stable support and warranty history than the pure Tuya-ecosystem clones in this category, even though independent reviews for this specific model are still thin.

Does the TQX work with Apple HomeKit?
Yes, natively, along with Alexa, Google Assistant, and Matter.

How many remote sensors can it support?
Up to five, using millimeter-wave occupancy detection rather than basic motion sensing, according to Lux’s own specifications.
