Review on 🔌 Enhanced Sonoff TH16 WiFi Smart Switch with Temperature Monitoring – Alexa & Google Assistant Compatible (DS18B20 Supported) by Leon Yulharmanto

Installed to aid in spa temperature control. The first thing I noticed was that the temperature sensor is far away. like 4F. but what the heck if it repeats itself, right? The app doesn't offer any graphs or historical information, in fact the barley of the app tells you if the device worked or not. There's no zoom, no adjustment, and nothing to tell you how often the sensor is polarized. Decent device, but why is the app so useless? Don't they understand that the application is the easiest part? I hate this Sonoff TH16 because of the app. Look elsewhere for another product with a better app.
