Freezer alarm

[journeyman713]

I purchased a pair of the SwitchBots for my vacation home last winter, to monitor house temp, and humidity below it. This summer the freezer went out, I added another one for inside that.
Just checked the battery life, it is 100% on the old ones, and 98% in the freezer. Thumbs up so far!

So satisfied, I just bought the 3 pack for my main home freezers.

Was skeptical of the wireless part working from inside the freezer, but it does. It comes with a hub, plugged in not far away, the hub talks to the sensors and my internet, perfectly.

The app on my phone is easy to use, and to setup alerts, at any setpoint.

Wouldn’t a temperature sensor be better than a door alarm? That way you’re covered if the freezer itself goes bad or the door is left open.

The yo-link does this with the weather proof outdoor sensors. Another nice thing is the sensors use AA batteries.

I use rechargeable AA's in my YoLink sensors. I've had them all probably pushing 3 years and only recharged the batteries once so far.

This isn’t specifically what you asked for, but our freezer wasn’t shut once or twice last year. Nothing went bad thankfully, but I installed one of these and it forced a reminder to always latch it back.

Can someone post the links of the yo link ones you'r using?

Amazon link to a great one, has saved me a bunch (4 commercial freezers that employees can’t seem to shut):

So this one mounts outside the freezer with the probe going inside, wire through the door I suppose?

Yes. But the door is most common and temp sensor I tried in the past didn't work well.
I've probably had the door open 2 or three times. Once the kids put a bag ice that prevented it from shutting, one time a jacket or something on top the freezer got in the door.
1 time I killed the breaker while working in the room and didn't turn it back on the same day.

And extra sensors without the display because I'm not digging into the freezers to look. I put the display ones in the incubators.

That is the intention, but I have 2 mounted completely inside and they work fine like that. I also have 2 others mounted as you describe.
