Bold is a Dutch smart lock brand, listed in its app as Bold Security Technology B.V. It makes the Bold Elite smart cylinder and the Bold Connect internet bridge, plus accessories such as the Bold Clicker and Entry Tag, and business products under Bold Pro. Everything is managed from the Bold app, which turns a phone into a key.
A Bold lock talks to the phone over Bluetooth. Bold Connect adds an internet link, and Bold's own pages say remote unlocking, lock status, alerts and the Google Home and Homey integrations depend on it. The Bold Elite also supports Matter over Thread, which needs no Bold Connect but does need a Thread border router such as a HomePod mini or Nest Hub.
That suits people who want a cylinder swap rather than a new lock body and who run Google Home, Homey or a Matter ecosystem such as Apple Home. It is weaker for older Bold locks, because Matter is limited to the Elite, and for anyone who wants a documented local connection to Alexa or Home Assistant without community add-ons.

Bluetooth
Yes
The lock works with the phone app over Bluetooth. Bold's Homey page says a Homey Pro can connect to the lock directly over Bluetooth, and a community plugin talks to the lock over Bluetooth Low Energy. Bold's product page does not name the radio, so the exact specification is unconfirmed.
Bold Connect is the bridge that brings the lock online. Bold's pages say lock status, Leave, Night and Tamper alerts and remote control need it, and that it is essential for remote access and stable automation with Homey. We found no Wi-Fi band specification.
The Bold Elite uses Thread for Matter. Bold states that Bold Connect is not a Thread border router, so a separate one such as a Google Nest Hub (2nd gen) or Apple HomePod mini is needed. Thread shortens battery life from about three years to about two.
Bold Elite is certified for Matter 1.4 and Thread 1.4, and can be paired to up to five ecosystems at once. Bold announced it on 10 November 2025 and says it is exclusive to the Bold Elite, with other Bold products working as before. Bold Connect is not needed. It is a Matter device, not a bridge or controller.
Listed by Bold as an official integration. It requires a Bold Connect: add Bold under Works with Google in the Google Home app, then open the Integrations tab in the Bold app. Voice unlock asks for a PIN code, which is managed in the Bold app. Bold's page does not state whether voice locking is supported. The Bold Elite can also join Google Home via Matter.
Bold names Amazon Alexa as a Matter ecosystem for the Bold Elite, with an Echo as a possible Thread hub. Bold's integrations list shows no dedicated Alexa skill, so older Bold locks are not covered.
Supported through Matter on the Bold Elite only, with a Thread border router such as a HomePod mini. For other Bold locks, a community Homebridge plugin connects over Bluetooth and exposes them to HomeKit.
Bold lists SmartThings among the Matter-certified platforms the Bold Elite works with. We found no separate SmartThings integration for other Bold locks.
Bold's integration list names Garmin among community-developed smart device integrations without describing it. Bold tells users to take questions to each project's own community.
No built-in integration found. Bold's own list names Home Assistant as a community integration, and a custom component by an independent developer exists on GitHub. The related Python library says it requires a Bold Connect. We could not confirm whether it is installable through HACS.
Bold describes Homey as a partnership and lists it as an official integration. Bold Connect is strongly recommended for a reliable connection and remote access. The Bold page says a Homey Pro can hold a Bluetooth link without it, and the launch post lists Homey Bridge over Bluetooth as a beta option. Bold's page does not mention Homey Cloud. The Bold Elite can also be added over Matter, and a community thread says lock status cards were missing that way.
Bold lists Homebridge as a community integration. The homebridge-bold-ble plugin connects directly over Bluetooth Low Energy, so no Bold Connect is needed, and fetches fresh keys from Bold's API every three to four days. It exposes only locks within Bluetooth range.
Bold lists API access through the Bold Web Portal for building custom integrations for public or business use. We could not open the portal's documentation to confirm terms or scope. A community Python library built on the API supports remote activation and deactivation and requires a Bold Connect.
