Not a fan of smart home appliances, to be fair, particularly because there's no way to ensure privacy of data and security. There was a paper presented at the Taipei Web Conference 2020 earlier in spring, which looked at the ease of compromising privacy and 2 types of identities simultaneously in multi-modal IoT environments, and that has over 70% de-anonymization success.
Basically, majority of IoT devices for your home are linked to multi-modal environments. All details are here, if I remember correctly, including the Gibhub link: https://thehackernews.com/2020/04/deanonymize-device-biometr...
As I know of, there's only one company which made progress on security in IoT devices, it's called Teserakt E4.
A quick tl;dr on what they offer / propose:
- Integrated implant in servers of IoT manufacturers.
- Complex end-to-end encryption for devices and different data flows.
- Open-source code (soon available).
Bottom line: Won't see it anytime soon.
