You guys have cool use use cases, I just use mine for the boring use case of in every single deep freeze, freezer and fridge. But man has it saved a whole fridge full of food from spoiling when someone (not me!) left it open in the garage.
It will chew through batteries though in the deep freeze, but it still lasts like a year plus. Haven't tracked it super detailed but at least that long. Maybe Il'l check my HomeAssistant battery graphs.

The sensor itself is currently $22 with a 10% off coupon, so if you don't need a hub, it's basically the same price without the extra e-waste.

If power goes out in your house (or wifi is down), are the sensors still reporting temperature so that when power/wifi comes back, you can see the rise/change in temp, i.e. a record of the power failure?

Consider the SpeakerHub if anyone additionally wants audio alerts from the hub. The YoLink kit with two temp sensors and Speakerhub is $54.99 on Amazon.

The temperature and humidity are stored for a number of days (perhaps 30 days, I haven't owned mine that long so not sure) The app gives you a graph of the data over your selected date range and you can export the data as a CSV file. So a power outage should not impact the data record.

Works great in guitar cases to monitor and notify you of low RH so you don't open the case someday and find a huge crack from drying out.....

This is a great deal! I already have several of these temp sensors and love them. I was shopping to buy more for some family members for Christmas, so glad to find this deal!

Second this concern. I don't think it includes the water leak sensor.
