“Chinese version from Ali” prolly means somebody slipped the plans to their cousin at another factory.

They did the best they could and used the parts they could buy the cheapest.

These are “interconnected” using RF which is now acceptable by code at least it’s when I checked with San Diego Fire Marshall. But YMMV. SD has interconnect (only within each apartment) and dual-power requirement in high-rise dwellings.

If there’s an interconnect dongle for old hardwire-connect detectors, you’d find it on/linked from above link.

They all have a 10 year mandated lifetime anyway. Maybe just replace all now?

Getting notified is nice.

Getting the FD notified is nicer.

Is OP going to carry the Raspberry Pi around with them to City X and City Y?

I’d imagine there are weather apps that can do this.

OP only wants a notification?

Smart plus ironically have phantom draw, though.

You’re good though, if your smart plug has less phantom draw than the thing you’re trying to stop the phantom draw from.

I once had a neighbor who would set up a camera on his kitchen counter when away on long trips. Pointing at the sink bowl. To detect backups. Which were frequent in our building. And he lived on the lowest floor.

Better than coming home to brown sludge.

Too bad for the poster with the water leak concerns.

They would only find out once the water starts pouring out under the doors.

Then it’s a useless system, though what’s it going to do for you?

If you’re concerned about living alone, and want cameras for security, first of all, you should have a comprehensive security system, and it should be professionally monitored, which means that there does need to be outside access .

The monitoring service will attempt to contact you, and then contact police or fire as appropriate.

alarm systems, generally have off, away, and home modes. In home mode indoor cameras should be disabled.

Customers networks, and then OP might be found liable. Especially if they had touted security.

The chances of them being secure are less than zero.

I’d have a really good liability policy if you’re planning on selling them and then be careful of your representations

companies that do the successfully go visit the factory themselves, and have experts evaluate product, safety, and security.

Even so, you have to constantly monitor for changes. Multiple factories produce the same product and there’s little respect for intellectual property the Chinese companies rip each other off left and right.

So the quality from a given exporter could radically change overnight.

You e got a mish-mash of brands and no real home automation controller.

A “network of Alexa’s” is not an HA controller.

That adapter is suitable for r/onejob

It’s labeled as an “AC/DC” adapter.

But it’s an AC/AC adapter!

RF is more difficult because too many standards and non-standards, and some of it is encrypted.

Don’t constrain yourself by insisting on a single device that does both .
