I’d love to get started writing addons for things like my air conditioner. It doesn’t have a public API, unfortunately. What’s the best way of getting started with something like this? It’d be great to have a collection of resources around this, because there are a whole lot of IoT devices with closed APIs, and it’d be awesome to crack them open.
Once you’ve done that, then you can start to think about the web api properties. You’ll probably want on an on/off property and a temperature set point property.
you can use packet sniffers like packet capture for Android to record (even encrypted) packets, send from your device.
Usually those api’s use XML and JSON, so maybe you can extract information about the api structure by reading packets.
