The tado° Smart AC Control V3+ is an infrared-based controller designed to manage split-system air conditioners and heat pumps through a smartphone application or voice assistant. According to tado°, the unit measures 100 × 100 × 15 mm, weighs 73 g, and features a capacitive touch display with an LED matrix. Internally, it includes sensors for temperature, humidity, ambient light, and ambient noise. Rather than hardwiring into the heating and cooling equipment, the device emits infrared signals directly to the air conditioner's receiver, mimicking a handheld remote. It is powered via an included 1,850 mm USB cable connected to a 5V power adapter.
Who it suits
This controller suits households wanting remote climate scheduling or voice management across Apple Home, Google Home, and Amazon Alexa ecosystems. Because it relies on external line-of-sight infrared commands rather than internal control board connections, it is particularly relevant for renters seeking a non-invasive upgrade. According to the tado° Help Center, compatibility is restricted to air conditioning units whose original remotes feature a full-state LCD screen displaying current modes and target temperatures. Households considering this device should be aware of several operational limitations. Automated geofencing and automated open-window shutoff require an optional paid Auto-Assist subscription; without it, the app only delivers push notifications prompting manual adjustment. Furthermore, each unit controls only a single air conditioner, and the system cannot detect status changes made using the manufacturer's physical remote control, which can leave displayed states out of sync.
Australian notes
In Australia, the Smart AC Control V3+ connects to regular mains power points using the supplied 5V USB power adapter. Renters considering mounting the unit to a wall should check their tenancy agreement before installing adhesive strips or brackets. The device operates exclusively on 2.4 GHz Wi-Fi bands (IEEE 802.11 b/g/n), meaning Australian dual-band routers must have an active 2.4 GHz network available. Local stockists include retailers such as Harvey Norman and Domotic Australia, and purchases made through authorised Australian retailers carry a 2-year limited manufacturer warranty supported by Australian Consumer Law. Note that the V3+ does not support Matter or native Samsung SmartThings connectivity, though local integration remains possible via Home Assistant's HomeKit Device integration.
