What to know about this device before choosing a connection.
A recommendation is not recorded yet. Compare the requirements below with your home and the capabilities you need.
Exact US commercial article 506.189.57. Smart-system use requires a compatible Matter controller and Thread border router; these requirements are distinct from standalone on-device readings. Documentation reviewed, not hardware tested. Sensor accuracy, minimum firmware, Home Assistant battery telemetry and update support remain unverified.
Check your ecosystem, then choose a connection method for its requirements and available controls.
A listed ecosystem is a starting point. Connection methods and exposed capabilities must be checked for the exact variant.

Documented
Scope is IKEA TIMMERFLOTTE US article 506.189.57. Manufacturer technical type E2314.
Documented
Sensor uses Matter over Thread, not direct Wi-Fi. Keep IPv6/mDNS working between border router and HA; IPv6 internet service is not required.
Documented
Use current supported 64-bit Home Assistant OS with its official Matter Server app.
Documented
Install Matter integration and connect its Matter Server. Thread integration alone is not the sensor entity integration.
Documented
Documented
Prepare Matter Server/integration, configured border router, IPv6 network and phone Thread credentials.
Documented
Insert 2 AAA HR03 batteries. New sensor enters pairing for 15 minutes. Press system button to reopen pairing; in TIMMERFLOTTE it is inside battery compartment. Scan device Matter code in Companion app.
Derived from documentation
After commissioning, verify temperature and humidity readings in final position before depending on automations.
Derived from documentation
Manufacturer documents temperature and Matter support. HA maps TemperatureMeasurement.MeasuredValue to a temperature entity. Exact-device exposure is a combined-documentation inference, not a hardware test.
Derived from documentation
Manufacturer documents humidity and Matter support. HA maps RelativeHumidityMeasurement.MeasuredValue to a humidity entity; exact-device exposure is inferred, not tested.
Not yet verified
Exact-article HA battery percentage/low-battery entities were not verified. Manufacturer battery indication in IKEA app is not proof of identical HA exposure.
Documented
HA Matter is Local Push and communicates over the local network without vendor cloud in the normal operation path. Platform documentation, not an exact-device interoperability test.
Derived from documentation
Configure HA remote access separately; remote notifications and services can require internet.
Derived from documentation
Local sensor entities can participate in HA automations; the host and every trigger/action dependency must remain available.
Not yet verified
Exact-article HA OTA support not verified. Matter OTA is optional and platform/border-router limitations apply.
Documented
Commission through the Home Assistant Companion app using the sensor Matter code, Bluetooth and the configured Thread network credentials. Controller and border-router onboarding must be completed first. Full Internet-free initial setup is not established.
Not yet verified
Not established. Downloads and mobile provisioning can require internet; distinguish those from local normal operation.

At least one compatible Thread border router is mandatory on the home network. A Zigbee-only radio/configuration is not sufficient. DIRIGERA is an example, not the only option for this HA route.
Not required
Native Matter path needs no protocol-converting bridge. This does NOT mean no hub/infrastructure: Matter controller and Thread border router remain mandatory.
Documented
Use a supported Android/iPhone with current Home Assistant Companion app and Bluetooth; keep it near the sensor and border router during setup.
Documented
Synchronize the intended Thread network credentials to the commissioning phone using official HA/phone-platform instructions.
Documented
Keep the unique device QR/numeric code. If already commissioned, obtain a sharing code from the existing controller instead of routine factory reset.
