The Boundary alarm system already integrates with other smart home products such as Amazon Alexa, Google Home and Smartthings but we do get requests for controlling other systems and integrations.
The Boundary alarm system has been designed in such a way that further integrations are absolutely possible as long as the IFTTT (If This Then That) protocol or SmartThings is available. This essentially means that it’s possible for our users to develop their own set of commands and actions as well as develop new integrations.
Other systems such as Home Assistant have a hybrid integration but you should bear in mind that for security we do not expose the sensor states on a local level and any integration will depend on a cloud connection.
