I agree, I'd also love to see integration with Canary -- however, without Z-Wave or Zigbee integration, I don't think it'd be easy. I haven't even seen them talk about an open API yet.
With that said, when asked if it'll work with other products
they responded: "The answer for now is…maybe and we hope so. While we admire and respect other products and companies like Smart Things and August, for now our focus is making Canary the best and simplest security product experience in the marketplace, unencumbered by the complication of other devices and solutions. Stay tuned for developments in this space."
I would love to see Almond or an independent developer for Almond reach out to Canary (or visa versa) to see how a potential API could be used to eventually integrate the two products.
