Normally we'd assign a Repairability Score on the last step, but we don't feel it's appropriate for this device. After all, there's a tamper-evident security seal for a reason.

Even so, we're glad to know that the smart meter doesn't have easily-breakable internal components, and can be serviced without difficulty by an authorized service technician.

A big thanks to Elster for providing us one of these meters! We certainly didn't want to take ours off the grid in order to mess around with it.
