Products
Garage door openers
Chamberlain Group markets several lines of garage door openers and related products:
- Chamberlain — do-it-yourself garage door openers sold under the Chamberlain brand.
- LiftMaster — garage door openers marketed to professional installers.
- Raynor — garage door openers for professional installers, but less widely used than LiftMaster.
- Craftsman — rebranded Chamberlain models sold at Sears; these products use a "139" model prefix to indicate Chamberlain Group manufacture.
- Clicker — universal garage door remote controls.
Chamberlain, LiftMaster, and Craftsman models have interchangeable parts, primarily the gear and circuit boards. The main difference between these brands is that Chamberlain and Craftsman units use a square-shaped split-rail system, while LiftMaster uses a single, solid inverted T-shaped rail.[5]
myQ app
Chamberlain's myQ smart garage door controller technology, which requires a monthly subscription, is embedded in garage door openers and lights,[6] and can be added to Wi-Fi networks to control these devices.[7]
At CES 2019, Chamberlain announced a partnership with Amazon, allowing packages to be placed in customers garages with myQ openers, as part of the Amazon Key service.[8]
Controversy
In November 2023, after previously ending Google Assistant support and discontinuing its official Apple HomeKit integration, the company disabled all other third party access to their "myQ" products, effectively stopping all open-source third-party integrations, like Home Assistant.[9] Writing for Ars Technica, Ron Amadeo interpreted the ban on "unauthorized" third-party integrations as driven by "Chamberlain's hardware-app-as-ad-platform strategy," describing the purpose of the myQ app as being "to display ads and upsell you on services."[10]
In December 2025, Chamberlain Group left the Connectivity Standards Alliance, the group responsible for the smart-home interoperability standard Matter, a move described by Jennifer Pattison Tuohy of The Verge as "locking users deeper into [Chamberlain's] proprietary, subscription-centric ecosystem".[1] As part of its Security+ 3.0 update, Chamberlain also blocked access to third-party aftermarket controllers for garage door openers such as Tailwind.[1]
