This smoke alarm looks very complex, and the amount of risk increases with the level complexity. For such a complex product, I would want to know some insights to the following.

What safety standards have been applied to the software development and product development?

Does it need wifi to work correctly?

Can you connect it to the mains power?

How secure is the wifi connection? ie Can it be hacked for malicious purposes?

etc.....

For something so critical to a life and death situation, I want something to function as simple as possible.
