Chamberlain Group, the owner of several garage door opener brands, has blocked its smart garage door openers from working with third-party smart home apps, citing the need to provide a better experience for its users and authorized partners. The company's app has been criticized for displaying ads and trying to upsell users on services. Users who were previously able to integrate their garage door openers with Home Assistant, a popular open-source smart home platform, are now being forced to use Chamberlain's app. Chamberlain recommends that affected users check out its authorized partners, which include companies like Amazon and Alarm.com.
