We have been experiencing inconsistency with SIM card usage with a few of our devices. We are currently using Electrons with each device using the same software, firmware, and each have the same electronics associated with them. They are all located within the same proximity of each other (RSSI of ~ -89), but each unit has a totally different SIM usage. These devices have been deployed for almost a year and has been consistent with each other up until recently. Here are some data usage graphs from a few of them:
Each of these devices had greater than 99% up time since September 23rd, the start of the cycle as shown on the pictures, but have different data usage. I have looked throughout the community forums and documentation. but haven’t found anything that suggests why this may occur. I have downloaded the history from these devices and found unusual things:
Device with 6.2 MB:
Device with 30.89 MB:
The devices with higher MB usage seems to have a spike in service.cloud.publish.sent and service.cloud.uptime. What do these two parameters describe and why do some of them spike while the others do not. Does this contribute into having a higher MB usage?
Are there any other things we should check to answer why these devices have inconsistent data usage?
