Great for greenhouse monitoring

Using this in my remote greenhouse has given me peace of mind. The app is intuitive and the data logging helps me track trends over time. Only giving 4 stars because the initial SIM card setup took a few tries to get right.

Perfect for my server room

I needed a reliable way to monitor temperature fluctuations in our server closet without relying on the building's WiFi. This 4G sensor works flawlessly. The instant phone call alert when the AC failed last week saved us from potential hardware damage.

Solid industrial tool

We deployed five of these across our breeding facility. They are robust and the battery backup ensures we don't lose data during power outages. The monthly data plan cost is reasonable for the security it provides.

Reliable and accurate

Compared the readings against a calibrated lab thermometer, and the accuracy is impressive. The ability to set custom thresholds for both high and low limits is exactly what I needed for my wine storage cellar.

Easy setup and great support

I am not very tech-savvy, but the instructions were clear. When I had a question about the APN settings, customer support responded within an hour. Highly recommend for anyone needing remote environmental monitoring.

No WiFi? No problem!

This is the best solution for locations without internet access. I use it in a detached workshop, and the 4G signal is strong. The SMS alerts are fast, and I love that I can check the status from anywhere.

5 FAQ

Q: Is the mobile app available for tablets or just phones?

A: The app is compatible with both smartphones and tablets running iOS or Android. The interface scales well for larger tablet screens, making it easy to view historical charts.

Q: Can this device work in areas with weak 4G signal?

A: The device requires a stable 4G LTE connection to transmit data and send alerts. If the signal is too weak in your location, the device may fail to send real-time alarms, though it will continue to log data locally until connectivity is restored.

Q: Can I receive alerts via email as well as SMS?

A: Currently, the system supports alerts via SMS text message, automated phone calls, and push notifications through the mobile app. Email alerts are not supported at this time.

Q: How long does the backup battery last during a power outage?

A: The internal backup battery is designed to keep the device running for approximately 4 to 6 hours during a power failure, ensuring continuous monitoring and alert capability.

Q: Does this device come with a SIM card included?

A: No, the device does not include a SIM card. You will need to purchase a standard Nano SIM card with a data plan from your local carrier separately.
