Aranet is the brand of SAF Tehnika, a Latvian wireless equipment company. It makes the Aranet4 CO2 monitor and related sensors for temperature, humidity, radiation and radon, which are read through the Aranet Home app over Bluetooth. A separate PRO line uses base stations and Aranet Cloud for larger sites.
Home sensors such as the Aranet4 HOME talk to a phone over Bluetooth and keep their own history, so there is no hub, account or Wi-Fi setup. Home Assistant can read them over Bluetooth once the Smart Home integration setting is switched on in the app. For bigger deployments the PRO line adds a base station that can push data to Aranet Cloud and offer MQTT, Modbus, BACnet and InfluxDB locally.
That suits people who want a battery-powered, display-first CO2 monitor and may feed it into Home Assistant. It is weaker for voice assistants and mainstream ecosystems: the pages we read mention no Alexa, Google Home, Apple Home, SmartThings or Matter support, and the home sensors are not compatible with Aranet Cloud.

The main app for Aranet sensors. It shows live readings, charts, up to 90 days of history, home screen widgets, data export, alerts when readings enter the red zone, low-battery warnings and firmware updates. It supports Aranet4, Aranet2, Aranet Radiation, Aranet Radon Plus and Aranet Radon One. Published by SAF Tehnika. The Android link uses the package name com.saf.aranetCube.android, taken from an AppBrain listing that describes the app as Aranet Home by SAF Tehnika A/S. We could not load the Google Play page itself to confirm it.
A web platform, not a phone app, for managing Aranet PRO and PRO+ base stations. It stores measurements from all paired sensors, offers live and historical views, sharing, and export to CSV, XLSX or PDF. Aranet's help page says Aranet4 HOME and Aranet MINI base stations are not compatible with it.

Connection
Bluetooth
Yes
Aranet sensors connect to the Aranet Home app over Bluetooth. Aranet's FAQ says Bluetooth is optional on the Aranet4 and used only when it is connected to the app. The datasheet lists compatibility with Bluetooth 4.1 and later and an extended-range option that shortens battery life.
PRO sensors pair with a PRO or PRO+ base station, which sends data to Aranet Cloud over HTTPS. An Aranet staff post on the forum calls the radio a proprietary, modified LoRa protocol meant only for Aranet devices. Base stations support Ethernet, Wi-Fi and LTE for the local integrations, with limits: BACnet is Ethernet only.
No Matter support or announcement appears in the Aranet pages we read, and we did not run a dedicated search for it, so we could not confirm either way.
A built-in Aranet integration supports Aranet2, Aranet4, Aranet Radiation, Aranet Radon Plus and Aranet Radon One. It finds devices over Bluetooth and is classed as local push. Devices need firmware 1.2.0 or later and the Smart Home integration setting turned on in the Aranet Home app. It arrived in Home Assistant 2022.12 and is maintained by the Home Assistant project, not by Aranet, though Aranet's forum points to it. A user on that forum suggested a Bluetooth proxy for sensors placed far from the host. A community project for Aranet Cloud also appears in search results, which we did not open.
Homey's store lists an Aranet4 app whose page names SAF Tehnika as the developer. It lists Homey Cloud, Homey Pro, Homey Pro mini and Self-Hosted Server, needs Homey 5.0.0 or later, and does not list a Homey Bridge requirement. Its newest version, 1.3.3, was updated about three years before the page was captured, and the install panel showed mixed compatibility messages. A separate community app by Patrik Husfloen describes itself as unofficial and says a Homey Bridge is required for the Bluetooth device. We could not confirm the vendor relationship beyond the store page.
We did not find an Aranet binding in the pages we checked and did not open openHAB's add-on list, so we could not confirm either way.

Local integrations (base station)
Official
PRO base stations can publish to an MQTT broker, serve Modbus TCP/IP and BACnet IP to building systems, and send to an InfluxDB v2 database. These need a licence file uploaded to the base station, with a free 30-day trial and 1-year, 3-year and unlimited options. MQTT is disabled by default and must be ordered and enabled separately.
Aranet Cloud has a pull-type API for retrieving sensor measurements and a push-type integration that sends data as SenML JSON to an endpoint the user runs. The base station must be registered on Aranet Cloud. We did not read the API reference and could not confirm any pricing.
Checked 11 November 2026 against the brand's own pages, app store listings and each project's own page. “Not found” means we searched and found nothing, not that it is impossible. Compatibility changes often. Spot an error? Tell us and we will fix it.
