Can You Use Chromecast with Smart Home Assistants?
Most Smart Home Assistant devices like Google Nest and Amazon Echo also double as Bluetooth speakers. You can pair Chromecast to use your Home Assistant as a Bluetooth speaker. The pairing will depend on your device, but it can be accomplished on separate Smart Home apps.  Smart Home Assistant devices provide good sound quality, and it is a good option if you aren't willing to spend money on a Bluetooth speaker. Moreover, you don't have to pair it with Chromecast each time you watch something on your TV. The smart home device will automatically pair the devices.
