Works Fine

I´m not using it at 100% because my acuarium it´s not ready, but i use for some few days in other acuarium and work fine for now.

Alarm notification

@Tracey Jones: it actually does alarm when/if the power goes off. The InkBird services send a push notification of it goes offline. Default is no alarm, but can be activated on the edit tab in the app. (not under settings, but where you rename the device)


This is a good device but instructions are incredibly lacking, as is evidenced by the setup video above. We just HOPE that it won’t dry our tank since we have no idea how to actually set it up.

Great product

Works well. Shame it doesn’t alert you when the power goes off

Great Thermostat

I love the thermostat just not too crazy about the fact in order to use app it only supports 2.4 Ghz and I have a 5Ghz so I can’t use app or connect to my WiFi
