As an extension to our anomaly detection example posted last week, we went ahead published the event data from a Photon along with glowfi.sh anomaly detection results and are feeding all in real-time to ubidots via webhook here: [image] glowfi.sh 3 sensor anomaly detection Check out my se…

Help me understand, how come the green line doesn’t cross/approach the threshold every time the temperature reading is bogus ? I see it lining up some times and not others.

@AndyW Great observation! There are a few reasons why this can happen. The two most relevant ones are webhook request failure, and statistical considerations. webhooks: In order to display glowfi.sh predictions along with raw sensor data, we send two POSTs to Ubidots. The first POST is data from …

Makes sense. Thanks for the explanation. So the webhooks failure you reference is not a particle webhooks issue but one between your servers and ubidots, and if these errors were eliminated and no data was lost, we would expect to see more excursions of the green line below threshold (but still no…

@AndyW Yes to your question about missing data. The glowfi.sh - particle webhooks integration is a somewhat complex one. For example, to get device, particle cloud, and glowfi.sh predictions to post to ubidots, the following sequence has to happen: Raw data publish from device, webhook post to ub…

To clarify, the webhooks we are using are particle webhooks not glowfi.sh webhooks. We will update the community when we implement our custom webhooks as an alternative. Mike

By the way, we just added the API call to reset the learning model for anomaly_detect with a POST to “ http://api.glowfi.sh/v1/anomaly_detect/reset_model/ ”. More info on reset_model here .

The dropped webhook responses we are seeing may be related to the issues discussed in this thread.
