Does anyone have a low-temperature alarm in their barn?

I would like to do the same. I have issues but my barn is a few hundred feet from my house.
I have unobstructed line of sight between the two structures but likely pushing 400'.

Like i said, the yolink devices from amazon will work. My building is about 500’ from the hub, never disconnects.

This is what I'm thinking of. One pack with hub. My barn is 30 ft from the house but is a metal pole barn and I presume that's no problem. Does this below look suitable for telling if the temp starts to get to maybe 40 degrees?

You can set whatever levels you want to be alerted to. But this link didnt have a hub.

Underneath it does show the item with a hub for a higher price. I think it's $35 or so.

The product he linked to says it uses LORA communications. 400' distance should be no problem.
