Ecobee Smart Thermostat Premium Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

ecobee is the best-performing ecobee smart thermostat premium brand in July 2026, moving 17,000 units across 4 ASINs for 47.2% of Top 10 volume. Sensi follows with 6,000 units (16.7%), ahead of Honeywell Home on 6,000 units (16.7%).

With 5 brands splitting the Top 10 and 80.6% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $56.50 to $165.25, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0BXZ6KXGG booked 1K units at $39.99, with ▲ 0.0% MoM change. On the growth side, B0CS8K4BX5 leads positive momentum with ▲ 500.0% MoM growth on 300 units, with B09X69FSMB close behind at ▲ 100.0% MoM on 2K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
