Inkbird Smart Thermometer Temperature and Humidity Monitor Hygrometer Indoor, Free APP for iOS and Android, IBS-TH2 Plus Version Supports External Temperature Probe and Digital Display

I love these, I have two, everything works well. Exactly as described and they seem pretty accurate and good quality. I think INKBIRD is good company. It seems they are not supported by the new INKBIRD APP, you have to get the ENGBIRD app instead, but this is in the instructions.

Engbird app doesn’t send you notifications/alerts to your phone even within Bluetooth range. Only alerts sent with app open which is useless. You have the app open I can already see by myself that temp is not within required range

Muy fácil de manejar,

Nothing brewing right now, but I didn't want to wait to try it out. Temperature has been below zero! I used the unit to measure/balance the room/furnace temperatures. Temperature and humidity measurements matched my existing instruments very well. Both the internal and external temperatures. Data logging and graphical presentation are great. Will be excellent for brewing. Never lost Bluetooth and we have three floors. Great price point for the features you get! I need another!

Su funcionamiento es muy limitado, cuando varios usuarios usan la aplicación del mismo termometro todos pueden cambiar los valores de las alarmas, debería poder establecerse un administrador y que a todos los lleguen las alertas, no ofrece mucho control o seguridad si las alarmas se pueden configurar por cualquiera, en el punto de acceso wi fi para conectar hasta cuatro sensores se conectan los primeros cuatro que lee, si son más de cuatro no hay control sobre los cuatro que se conectan en cada punto

I compared it to a lab quality thermometer from 0c to 45c and it was accurate. It syncs and displays on my android phone without issue. I found the range was limited to 30 feet to 50 feet in open areas and less if a wall or other barrier was in the path. I have wireless (non-network) barbeque thermometers, and indoor/outdoor thermometers that work reliably anywhere in the house and yard. If you want to monitor something within the length of the sensor cable and periodically transfer the data to your phone (it makes nice graphs) when you are near this is a 5 star product.

Good but not practical, you have to be within bluetooth range for it to even show you the readings. I bought it so i could check when i was not at home…
