I mean I'm kinda curious in smart machines that I can hookup to my own dashboard or self hosted smart assistant to automate something like make coffee every day at 9am. Or to see how long till the laundry is done. But I would never let a smart device connect to the cloud aka internet. I'd isolate it on a clan and I'd probably be sniffing the network traffic and autosave the last month of traffic. I trust my network....I don't trust devices that run who knows what firmware/software. I know it seems paranoid and to some it probably is but iv read to many storied of smart devices being insecure or the company going under and then you being left with something that dosnt work because it can't talk to their cloud server. I like the smart tech when I'm in control of the data and not reliant on some company.
