Looks cool! I’m wondering how you would deal with cumulative errors. Lets say you have a meeting room with one door with one sensor, and the sensors has a 99% accuracy. If 100+ people walk through the door, the sensor could still report 1 or 2 persona in meeting room, while nobody is there. Do you have work arounds for this problem?

Yes, we have active R&D projects focused on addressing this kind of drift. In smaller rooms where the environment is favorable, we will usually see the device count for a whole day without any mistakes. But in general there are diminishing returns with that strategy, and there are lots of possible ways to correct drift error. I'm not sure how much more I can say right now.

>4. We need a way to execute actions on failure.

CodePipeline has codebuild and lambda integrations, you could use the lambda functions to do what you want after success/failure.
