Blast my addled brain. I swear one of their products was hard-wired.

Good luck on your hunt and let us know where you land!

Yes the MSC-1 is battery only. There is another part number that is smoke only and interlink/hardwired.

Sidenote: you can click through for the UL x-sense products here.

I just went through this battle and ended up ordering a set of sensereo MS-1 (matter over thread and home assistant ready) to replace the battery-only detectors in our basement. Our main floor is nest protect hard-wired.

While this product isn’t UL certified, it is EN certified and the functional difference seems to be 85db at 3m vs 10ft. And their website says they’re working on a UL certified model.

They do have a hard-wired interlink model too: https://sensereo.com/ms-1-interlink/ but that’s smoke only. And again EN certified but not UL.

But at least it’s an alternative to the x-sense products.

The reviews of the official replacement (FA SC-5) are mixed to awful.

Dammit.

If you need to change the references in the compose or env files:

• use sed to replace text in .env
• use variables and interpolation in compose

rsync

Built-in, picks up where it left off if you accidentally cancel it by running the same command again, and dead simple.

Permissions for the files will probably be a little broken moving to Linux, but chmod is also easy to use and can work at the directory level.
