A home automation (HA) system may include addressable HA devices, and a processor and a memory associated therewith. The processor implements a message queue for generating generic messages for respective ones of the plurality of addressable HA devices and implements sandboxed bridges each configured to convert a generic message from the message queue into a specific message for a given one of the addressable HA devices. Upon a failure of one of the sandboxed bridges, the processor reloads the failed sandboxed bridge while maintaining operational the other sandboxed bridges.
