I would like the ability to setup a Webhook ( like on Github https://developer.github.com/webhooks/ )
within the settings of a temperature sensor that would send data on a interval bases like every 10 sec.
The data could be received by another Pi that is running a smart mirror ( https://youtu.be/sh2EJzplkpM )
The Webhooks could run internally right from the Pi running Cayenne to work on a local network to prevent extra load on Cayenne servers.
Here is another example of Iot devices using webhooks, this one however first passes through external servers which could be problematic if you are just working on a local network. https://docs.particle.io/guide/tools-and-features/webhooks/
