Review on 🌡️ Inkbird IBS-TH2 Wireless Bluetooth Thermometer Humidity and Temperature Monitor for Android and iOS - Smart Sensor for Freezers, with APP Control by Naoka Garcia

Works great so far. I have in the freezer. I use a temperature measurement app. I get a notification on my paired Bluetooth phone when the temperature is outside of the specified range. I get NO notifications when I'm not at home as it uses Bluetooth and not Wi-Fi. I can display daily, weekly or monthly rates with a chart. You can set the measurement to every 10 seconds, 30 seconds, 1 minute, 10 minutes, 30 minutes or less. I have previously set it to every 30 minutes. The display in the application shows that the temperature in the freezer remains within one degree of zero. Now I know if the freezer is cold so I don't lose all the food. Be sure to use lithium batteries to protect against cold in the freezer. UPDATE: Bluetooth pairing ended after 5 days, so now it's useless. I can't set the pace.
