Maintenance and offline use^[5][8][10]

• Batteries: 1x rechargeable LADDA AAA (HR03) — sold separately, not included — manufacturer-stated 15 months per set
• Works without the internet: Yes — the core function runs on the device or your home network. A vendor cloud may still be involved in remote access.^{[10][26][36][46]}
• Matter over Thread runs locally; IKEA's support policy states smart products keep working, including on local networks without internet, after software support ends. Bluetooth is the commissioning radio (CSA cert); pairing is by QR code. Battery life is IKEA's own published figure: '1 x new LADDA AAA HR03 battery will power this sensor for about 15 months before it needs to be changed', from IKEA's manual rather than the product page. A red LED shows when the battery is low, and battery status also appears in the IKEA Home smart app. Radio: 10 m range in open air, 2402–2480 MHz. Operating temperature 0–40 °C (32–104 °F); IKEA states 'Use only indoors' and that 'The product is only suitable for mounting at heights up to 2m.' Support duration: at least 5 years after purchase per IKEA policy, conditional on pairing with a DIRIGERA hub or TRADFRI gateway; the policy does not address the term for Matter devices used only with a third-party controller.
• Security updates: IKEA states its security-update commitment for this model as a period rather than a date: software support for at least five years after purchase, which is IKEA's stated policy for its smart products as a class and which IKEA writes as conditional on the sensor being paired with a DIRIGERA hub or a TRÅDFRI gateway; the five years count from each owner's purchase date rather than from a launch date, so no single end date exists for this model, and the same policy commits to a minimum of three years after purchase for the hub or gateway itself (the document this comes from names no country, so which markets it legally covers is not stated). That is a floor measured from a starting point the manufacturer sets — a launch or a purchase — rather than a fixed end date, so it cannot be placed on a calendar here. We record the commitment as the manufacturer states it, in our words, rather than converting it into a date it did not give. This is a published commitment, not a gap in our research.^{[21][26][36][46]}

Who it's for

Households already running a Thread border router in any Matter ecosystem who want door and window open/close triggers at the lowest price in the category, and DIRIGERA homes extending IKEA's own sensor lineup.
