This would be correct. We have at least 7 amazon alexa/fireTV devices and a bunch of other IoT devices with Alexa capability and each of them get used regularly.

The IoT devices are on their own subnet which doesn’t have access to the other subnets. I live with my mom and Alexa devices just make her life way easier. I put in the work to make sure the alexa and IoT devices are as restricted as possible without losing functionality so she can live a bit easier.
