- Does the device have internal storage?
Yes. It has a large internal storage which can store up to 300,000 sensor readings. This can ensure the offline use in conditions where WiFi network is unavailable.
- Is the 200MB of storage and 1GB of outbound traffic for lifetime use on my account or monthly?
Pricing plans are at device-level. e.g. The free 200MB storage and 1GB outbound traffic is for each device. If you have multiple devices, each of it will have 200MB storage and 1GB outbound traffic. 200MB storage is for lifetime and 1GB of outbound traffic is rotated monthly.
