Re-architected for reliability and trend analysis
At the lowest level, Siren is split into 2 tiers: the first tier processes raw sensor data from the Okra Pods and the second takes a higher-level look at which rules should be triggered for the day, and over a lookback period, to identify trends. Sometimes issues come up for a brief moment and resolve themselves, not warranting labour spent to investigate, so Siren is careful to only raise concern over issues that seem to be persisting.
Reliable blackout triggering
In some cases, we haven’t yet identified why a blackout occurs but instead of letting that go unnoticed to the customer, we restructured Siren to ensure reliable electricity for the household is the highest priority. So if a household experiences recurring blackouts, and the root cause is unknown, Siren will alert the maintenance manager to investigate further. This “catch-all” also serves as a learning tool for our data team to pinpoint gaps where specific logic can be applied.
Power thief developed and maturing
This rule continues to be fine-tuned and is currently only visible for Okra staff to scrutinize, as we need to be extremely confident of our findings before approaching a household with suspected tampering. The rule has been trained on existing confirmed cases of power theft and is steadily becoming much more reliable as we gather more field data.
