Zero Data Loss Guarantee
No measurement is lost, even if the internet drops or the server restarts. The local queue holds the data safely and transfers it automatically once the link returns - nothing is deleted without server acknowledgement.
No measurement is lost, even if the internet drops or the server restarts. The local queue holds the data safely and transfers it automatically once the link returns - nothing is deleted without server acknowledgement.
In cloud-only systems the live readings are lost as soon as the link drops, leaving a gap that matters for billing and alarms.
No data can be received during a backend update or maintenance, and that window falls out of the energy analysis.
Seasonal facilities and remote sites can go without a connection for weeks at a time.
If the same measurement is written twice on retransmission, the figures break and alarms fire incorrectly.
The field agent writes every measurement to the local queue first. It is not removed from the queue until it has been written to the server.
The server acknowledges that it received the measurement. No record leaves the queue before that acknowledgement arrives.
The local queue capacity keeps every reading safe even through a long offline period.
Once the connection is restored, the accumulated data is sent automatically in chronological order - no manual intervention.
If the same measurement is written a second time, the system silently ignores the duplicate record.
An early-warning alarm as capacity is approached - the site's connection problem is detected before it bites.
Most sites in Turkiye stay offline for at most a weekend plus a public holiday. Thirty days is a generous buffer for both seasonal shutdowns and unexpected communication faults. The buffer duration and size are configurable.
The measurement stays on the field side until it is acknowledged by the server. When the link is re-established, every pending record is sent again. Even if the same measurement is sent more than once, the system prevents duplication.
Transfer is acknowledgement-based; a measurement is held on the field side until the server confirms it - zero data loss.
The queue never deletes data; when capacity is reached it raises an alarm. That design is deliberate: detecting the problem early is preferred over discarding measurements.
| Offline Buffer | 30 days of local retention |
| Transfer | TLS-encrypted, acknowledged (ACK) communication |
| Data Loss | 0 - raises an alarm when the queue is full, never deletes |
| Duplication Protection | The same measurement is never written twice |
| Queue-Full Alarm | Early warning as capacity is approached |
No measurement is lost, whatever happens to the internet link or during server maintenance.
