I decided to try my hand at brewing beer at home during the ongoing COVID-19 pandemic. I bought this Bluetooth-enabled digital thermometer/hygrometer so that I could continuously monitor the temperature around my fermenter, as maintaining a critical temperature range is very important to producing a nice tasting beer. Rather than investing many hundreds of dollars in temperature-controlled fermentation systems, I put together a budget system myself using a 2-gallon fermenter, reusable cold packs, heavy bath towels, and this Bluetooth digital thermometer/hygrometer.
I love new tech, especially inexpensive tech devices that provide real utility, value, and innovation, and this product has exceeded my expectations in all of these areas. The device easily paired with my smartphone, and the app is very easy to use. The temperature and humidity data captured from the device by the app can be displayed and reviewed across different time intervals, and the adjustable temperature and humidity alerts have been exceptionally useful. No matter where I am in our home, I can continuously monitor the temperature and humidity around my fermenter. Additionally, the thermometer/hygrometer sends alerts directly to my phone when the parameters I have set have been reached or exceeded, so that I can remove or add cold packs as needed.
I can see many other potential uses for this device. Unlike my disappointing experiences with some other inexpensive new tech devices and/or their smartphone apps, this product and its app really deliver great utility, value, innovation, flexibility, and ease of use.
It works, and it was easy to connect to the phone via Bluetooth. But it is impossible to see anything on that LCD screen.
Update: Seller send updated version with much better screen.
