Build quality & everyday use

What carries the tado° V3+ Starter Kit in everyday use: Broad smart home integration (Alexa, HomeKit and Matter) and Geofencing (heating off when everyone leaves home). You have to be honest about the weaknesses: bridge required. The extra hub has to be connected to the router.

If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.

“tado° Smart Radiator Thermostat V3+ Starter Kit: broad smart home integration and geofencing. The trade-off is that a bridge is required. At 9.0/10, a clear recommendation from €150.”

Frequently asked questions about the tado° V3+ Starter Kit

Do I really need the tado° subscription?
Not for the basic functions. Schedules, app control, manual heating and open-window detection work free of charge. The tado° Auto-Assist subscription (€3.99/month or €25/year) unlocks geofencing (automatic switch-off when you are away) and the weather/maintenance features. Without a subscription it remains a full-featured app thermostat.
Does the tado° fit my radiator?
On 95 % of all German radiators (standard M30 × 1.5). Adapters for Danfoss RA, RAV and RAVL are included. If in doubt: send a photo of the valve connection to tado° support, who help free of charge.
How much heating cost do I realistically save?
Common estimates put the savings at 6 to 10 % from schedules and open-window detection, plus 2 to 5 % from geofencing. With a gas bill of €1,500 per year, that is a saving of €120 to €225. The purchase pays for itself after 1 to 2 heating seasons.
Does tado° work in a rented flat?
Yes. The thermostats are screwed onto the existing valve without tools. When you move out, simply take them off and screw the old thermostat back on. No structural changes, no landlord permission needed.
What is the difference between V3 and V3+?
The V3+ additionally has open-window detection via air-pressure sensing and Care & Protect (maintenance prediction). The V3 (without +) is older and being phased out. We recommend the V3+ Starter Kit.
Do I need a thermostat for every radiator?
Yes, one thermostat per radiator. The starter kit contains 2 thermostats + 1 bridge. For further radiators, buy add-on thermostats (from €70); the bridge controls up to 50 devices.
