Best Buy is currently offering the BISBISOUS Smart Radiator Thermostat Valve for $114.41 CAD (reg. $228.82, save 50%).

Free shipping on orders over $35 CAD.

Featuring an ABS plastic housing with a stainless steel valve shaft, this smart thermostat valve supports 0–100% control in precise 1% increments with internal calibration, so every setting is executed reliably without unnecessary fluctuations.

A key highlight is open-window detection: the actuator recognizes an open window (via connected window contacts or a manual app trigger) and temporarily switches off heating, helping you save roughly 15–20% on your monthly energy bill.

Control everything through one app — time scheduling, group control, manual corrections, and automatic scenarios — plus Alexa voice commands. The compact white design blends seamlessly into any interior.

It also provides detailed daily energy data so you can see when you heat the most and where to optimize, ideal for energy-conscious households.
