## Questions & Answers

**Q: Can the metrics be changed, for example Fahrenheit to Celcius?**
A: Yes, there is a dedicated switch to change between Fahrenheit and Celcius.

**Q: Is there a warranty? Mine broke after 5 months**
A: Hello, the Warranty shall apply to Aranet 24 months after it is shipped to the customer. Please use the Returns Support Centre to claim for a repair or replacement.

**Q: This says it has a battery life of ~4 years but I can't see anywhere that says how many hours it lasts between recharging. Can anyone advise, please?**
A: I think that literally means the batteries will last 4 years. It's an e-ink display like a kindle so it should only consume energy when updating the display and the electronics must be minimal energy. The exception might be if you use the bluetooth connectivity frequently, I guess. I've had it running constantly on the 2 AA batteries it came with for ~4 months without a problem so far.

**Q: Can a single app show the data from multiple devices?**
A: There are 2 Android apps available, Aranet4 and Aranet4 Display. Either app allows you to scan for additional sensors. I don't have multiple sensors to test this but from the app screens, I think the former allows you to show multiple sensor readings on the same screen (small for personal viewing) whereas the latter shows the selected sensor in big characters (for public viewing from a distance as a possible use scenario).
