Elro is a European home safety and smart home brand, sold under the trade name ELRO Europe. Its Elro Connects range pairs plug-in switches, motion detectors, door and window contacts and smoke, heat, CO and water detectors with a K1 or K2 connector, and everything is managed from an Elro Connects app.
Elro Connects devices talk to a connector that plugs into a mains socket. Elro's manuals and product pages name an 868 MHz radio link between the connector and the accessories, not 433 MHz, and the connector is linked to the home network and the phone app. Two generations exist: the K1 Connector with the ELRO Connects app, and the K2 Connector with the ELRO Connects 2.0 app. We found no voice assistant, Matter or Apple Home support on Elro's own pages.
That suits a simple, mostly safety-oriented setup with scenes, notifications and plug-in switches, run from one app. It is weaker for broad smart home integration: the open platform support we found covers only the older K1 connector, through an openHAB binding and a community Home Assistant add-on, and we found no Homey app.

The app for the K1 Connector. Its App Store listing describes remote control, scenes, alarm monitoring, push notifications, Wi-Fi setup and alarm history, and the version history mentions thermostats and smoke, CO, water and heat sensors. The listing names ELRO Europe as developer and CoSa Connects B.V. as seller. The listing does not mention the K1 by name, but the K1 manual names this app.
The app for the K2 Connector, described as the base station with a built-in speaker and LED. It sets scenes and automations triggered by motion or door openings, and covers fire safety, intrusion protection and comfort devices. Published by ELRO Europe.

The K1 manual lists RF at 868 MHz only and gives a range of 100 m or more, and Elro's K2 Connector page also names 868 MHz. Neither mentions 433 MHz. The connector acts as the hub for all Elro Connects accessories.
The K1 manual says the K1 joins the home network over Wi-Fi (802.11 b/g/n) during setup. Elro's K2 page does not mention Wi-Fi, only that the connector is set up through the app.
Not mentioned on Elro's smart home, K1, K2, switch or detector pages, or in the app store listings we read. We searched for an Elro Alexa skill and found none, so we could not confirm any support.
No built-in integration appears on Home Assistant's integrations list. A community integration by one developer, installable through HACS, supports the K1 connector only; its README says the K2 does not work. It uses the connector locally after a one-time cloud sign-in and polls about every 15 seconds.
We found no Homey app for Elro Connects. A Homey community thread from 2021 to 2023 asks for K1 support and shows no answer from Elro or Athom. We did not find a store page, so this is unconfirmed.
openHAB lists an ELRO Connects binding. It talks to the K1 Connector using UDP on the local network, with an optional cloud account only for discovery. It covers smoke, CO, heat and water alarms, door and window contacts, motion sensors, temperature and humidity monitors and plug-in switches. The page does not say that Elro maintains it, and testing was limited to smoke and water detectors.
No official Elro API found. The openHAB and Home Assistant integrations above use the connector's local network protocol, which Elro does not document on the pages we read.
We could not confirm any relation between Elro and Smartwares. Business registry listings name ELRO Europe as a trade name of CoSa Connects B.V. in Klein Zundert and mention no parent or group.
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.
