Method: Roster of 11 connected smoke/combo smoke+CO devices plus audio "listener" accessories, after adversarial re-verification. All checks were WebFetch against source pages (WebSearch was unavailable); several retailer/manufacturer pages (X-Sense, Amazon, Lowe's, Best Buy) block automated fetches, and the Google Store is geo-consent-gated, so a number of prices are set to null rather than guessed (a null beats a guess). One draft entry (X-Sense "SC06-WX") was REMOVED: its own cited review covers only the RF-interconnect SC06-W (sealed 10-yr battery, Link+ mesh, no Wi-Fi) and makes no mention of any Wi-Fi "SC06-WX" model, whose specs/price were extrapolated. sensor_life_yr is the manufacturer-stated sealed-battery/sensor rated life in years (null when only a warranty period, not a life rating, is stated; null for the audio-listener accessories, which have no smoke/CO sensor of their own). Confirmed live prices: X-Sense SC07-WX $44.99 (the-gadgeteer), Kidde P4010ACSCO-WF $89.97 (Consumer Reports), Ecolink FireFighter $39 (Home Controls); Nest Protect held at $119 (canonical, store page consent-gated). Discontinued First Alert/Onelink models and blocked X-Sense/Ring listings had unverifiable prices nulled. Kidde voice_location_alerts nulled (Kidde voice output not confirmed as location-announcing; that is a First Alert feature). All prices USD; generatedAt and every accessedAt = 2026-08-16.
