IKEA will start selling its LILJEBAGGE smart radiator thermostat in Germany at the start of 2027. An IKEA spokesperson told heise online on 19 October 2026 that sales are planned to begin "right at the start of the new year". The German product page, so far reachable only through a direct link in the IKEA app, lists the price as €14.99. IKEA has not confirmed that price and says it could still change before launch.

Cheaper than in Sweden

The thermostat is already on sale in Sweden for 199 kronor, just under €18, so the German price would be lower still. heise compares it with the thermostats from Bosch, Homematic IP and tado in its own test: even on sale, those cost several times as much. The cheapest model in that test, TP-Link's KE100, costs around €30 and needs its own hub. Cheap Zigbee thermostats from Sonoff or on the Tuya platform cost about the same as IKEA's, but they need a Zigbee gateway.

Thread, not Zigbee

LILJEBAGGE is part of IKEA's new Matter-based range, which is gradually replacing the company's Zigbee devices. The thermostat talks over Thread. To control it from a phone you need a Thread border router and a Matter controller. Many smart speakers and streaming boxes include both. Besides IKEA's own DIRIGERA hub, IKEA names Amazon, Apple, Google, Homey and Samsung as compatible platforms. Home Assistant is not on IKEA's list, but heise notes that it also works as a Matter controller.

It also works without a smart home

Without a hub, LILJEBAGGE works as a manual thermostat. A small display shows the set temperature, and two buttons change it in half-degree steps. If the internet goes down, it keeps the last setting and can still be operated on the device.

Other details from heise:

  • power from two AA batteries, not included; IKEA expects about 18 months on two fresh LADDA rechargeables;
  • six adapters for different valve types in the box;
  • the valve is moved regularly to stop limescale from building up;
  • a frost protection mode to keep pipes from freezing.

IKEA has not said whether LILJEBAGGE detects open windows and turns the heating down by itself.

What is still unknown

IKEA has not said whether bundles with other devices will be offered, and the €14.99 is still only a price on a hidden product page. heise's report covers Germany only. The sources do not mention a launch in Poland or other countries.
