Hey there @rocksetta – that is the Device Cloud pricing for Wi-Fi devices (Photons, Argons), that are not acting as gateways in a Mesh network. Mesh pricing (post-preorder) is accessible by toggling the rocker to "Mesh" and selecting either "Wi-Fi gateway" or "Cellular gate-way".
Building support for high availability networks is near the top of our list along with Bluetooth API support and Sleep mode support in the Device OS. We need to certain that stability continues to improve before strongly prioritizing new features, but recognize that perhaps the most important new feature for many of our Mesh customers.
