Easy setup without WiFi

Didn't need WiFi which was great for my remote storage unit. Just inserted the SIM card and it was working within minutes.

Livestock barn essential

Monitors humidity perfectly during winter. Helps me ensure the ventilation is working correctly for the animals.

Great alerts but app could be nicer

Works well for greenhouse monitoring. The SMS alerts are instant. I wish the mobile app interface was a bit more modern, but functionality is solid.
