Help Freezer alarms


Veteran Member
I know, I'm full of questions this week.
Okay, the situation is I have deep freezers in a detached garage. Due to some issues with one, I want to put alarms in them so if one craps out I don't lose everything in it. The problem is that I don't go in the garage every day and it would be too far for Bluetooth. But, I have some pretty good WiFi coverage. And if needed, I could install a booster.
Does anyone know of good freezer thermometer/alarms that I could connect into the wifi? Even an app on the phone that would alert me if the temperatures got too high?
Thank you.
