Nexa is a Swedish smart home brand whose System Nexa range covers 433 MHz plugs, dimmers, wall switches, remotes and sensors, plus newer Wi-Fi devices. Devices are paired and automated through the Nexa Bridge hub and its app, and the bridge also handles Z-Wave and a few third-party products.
Nexa's gateway is the Nexa Bridge, which uses an Ethernet connection to the router and radios for 433 MHz devices and, on the original bridge, 868 MHz smoke alarms and Z-Wave. The newer Nexa Bridge 3 needs a separate Z-Wave adapter. The Nexa Bridge app's listing says the system runs locally without internet, with push notifications needing the bridge to be online.
That suits people who want inexpensive 433 MHz switching with local automations, energy monitoring and optional Z-Wave devices. It is weaker for voice and Matter: we found Google Assistant only in a retailer listing, no Alexa or Matter mention, and Home Assistant support comes from an unofficial community integration.

The app for the Nexa Bridge hub. The App Store listing, published by Nexa Electronics, covers pairing devices from different makers, energy tracking, spot-price notifications, alarm notifications, GPS geofencing and local operation without internet. Version notes mention HomeKit support and Sensibo support, and some features need Bridge X firmware 2.2.0 or later. The listing shows version 3.1.4 dated 29 October 2022. The Android link uses the package name se.nexa.nexabridge2 from Nexa AB's Google Play developer page, and we did not open the listing itself. We found no app named Nexa Home.
The official app for the Nexa Smart Hub, listed under Nexa AB on Google Play. It controls System Nexa receivers, with timers, switching and dimming, over Bluetooth LE from an Android device. The listing was last updated on 11 September 2024. We found no iPhone listing.

433 MHz (proprietary)
Yes
System Nexa devices use 433 MHz. The Z-Wave Alliance entry for the Nexa Bridge lists 433 MHz for Nexa devices and sensors, and Ahlsell lists the Bridge 3 at 433-868 MHz and compatible with System Nexa products. Athom's Homey app lists 19 Nexa 433 MHz models, and says other plugs and remotes may work through its generic entries.
The Z-Wave Alliance lists the Nexa Bridge as a certified central static controller for the EU region, with a 40 m radio range. The Nexa Bridge 3 needs the separate Z-Wave adapter ZWD-104, which Ahlsell lists as supporting two-way communication and mesh networking.
The Z-Wave Alliance entry lists a wired Ethernet connection for the Nexa Bridge, and Bauhaus lists 10/100 Ethernet with a cable for the Bridge 3. Athom's Homey app also lists six Nexa Wi-Fi or LAN models (WBD-01, WBL-01, WBR-01, WPD-01, WPO-01, WPR-01).
Nexa's Hubbe app for the Nexa Smart Hub connects to the hub over Bluetooth LE from Android. We did not confirm whether the Nexa Bridge itself uses Bluetooth.
The Z-Wave Alliance entry says the Nexa Bridge also has 868 MHz for connecting smoke alarms. Athom's Homey app lists a Nexa FS-558 smoke alarm among its 433 MHz models, so we could not reconcile the two.
Elgiganten's Nexa Bridge 3 page lists Google Assistant as the only voice assistant. Hornbach's page for the same product has only a data-sharing note referring to third-party services such as Google Assistant. We found no Nexa page describing the setup.
The Nexa Bridge App Store listing says versions 3.1.0 and 3.1.1 added HomeKit support. We found no separate Nexa setup page, so how the bridge's devices appear in Apple Home is unconfirmed.
We did not find a SmartThings integration in the pages we checked. We could not confirm either way.

Philips Hue, Sonos and other add-ons
Official
The Nexa Bridge listing mentions pairing products from other makers such as Philips Hue and Sonos, and Elgiganten lists Philips Hue, Sonos, IKEA Tradfri, Twinkly, Govee, Ajax System and Sensibo for the Bridge 3. A Z-Wave listing site says small add-on programs run on the bridge.
We could not confirm any relationship between Nexa and Telldus. Athom's Homey page says its direct 433 MHz connection removes the need for a Nexa Bridge or TellStick, and a Home Assistant forum user reports switching from a Nexa bridge to a Telldus bridge. The Telldus pages we read do not mention Nexa.
No built-in integration found. The community project ha-nexa-bridge-x, installed through HACS, lets Home Assistant control devices set up in the Nexa app, including switches, dimmers, sensors, energy data, and linked Hue, Tradfri, Twinkly and Sonos devices. It targets the Bridge 2 (sold as Bridge X) and supports the Bridge 1 and Bridge 3. It is MIT licensed and unofficial, though its author thanks Nexa for developer documentation. We could not confirm whether it works locally.
Nexa AB publishes an official Nexa app for Homey, listing Homey Cloud, Homey Pro, Homey Pro mini and Homey Self-Hosted Server. It covers 25 models, 19 on 433 MHz and 6 on Wi-Fi or LAN, and marks every model as needing a Homey Bridge. Athom's Homey page says devices connect directly, so no Nexa Bridge is needed.
We did not find a Domoticz plugin for the Nexa Bridge in the pages we checked. We could not confirm either way.

Nexa Bridge local API
Community
A community gist documents a local REST API on the Bridge X: web endpoints under /v1/ on port 80 and WebSocket feeds on ports 8887 and 8888, with HTTP Basic authentication and a shared factory login. The gist links some endpoints to Nexa's own documentation, which we did not open. Its author also reports security problems, including command injection in the API. We found no Nexa developer page.
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.
