Fyi theres a lot of mis-information in that thread.
If your house was built prior to the current building codes and only uses battery operated smoke alarms, you can replace them with battery operated smoke alarms (such as the battery operated Nest).

If your house currently has hardwired smoke alarms, you have to replace them hardwired smoke alarms (such as the hardwired Nest) as battery operated smoke alarms are lowering the level of safety.

If your house currently has interconnected hardwired smoke alarms, you must replace them with interconnected hardwired smoke alarms (they all go off if one goes off) as battery smoke alarms or non-interconnected smoke alarms are lowering the level of safety.

Current building codes which include all new builds or anyone taking out a permit to renovate their house, asks for hardwired, interconnected smoke alarms with a strobe (every level + all bedrooms). The nest smoke alarms do not contain a strobe that meets the required levels in the current OBC.

Im a fire inspector so feel free to post this info in that reddit thread. Any questions or if you require an in-person visit just call your local municipality fire prevention division. Its free (well technically your property taxes pay for it).

What about CO2 detectors in the current code?

I went through this.

Just install an extra alarm on each floor and merit the red interconnect wires coming into the box. Or go off an existing light fixture.

I think the issue is that the Nest alarms are interconnected wirelessly, not hardwired (the connection, not the power source). Technically that violates the code, and we're still waiting to see if there's going to be an update regarding wireless interconnection.

interconnect functionality of smoke or Carbom monoxide alarms is not a mandatory required function, it is more of a nice to have, so as long as the alarm is present in a house you are good, now for a mdu or other type of building other than a house the building codes are different but for a simple house, nest should do fine

We have interconnected ones but our alarms are battery operated and not hardwired either.

Is that a problem or just a risk? Meaning the alarm SHOULD still go off right? Its just that the others wont if it does not detect anything...

I thought wired nest protect was hardwired for power not for connectivity like older alarms alerting each other. I thought nests only communicate wirlessless to each other. Which at the time I research did not meet code of hardwire interxonnected

I could be wrong it's been awhile
