Ziggurat is an experimental Zigbee stack written in Rust. In contrast to microcontroller based Zigbee stacks like EmberZNet and Z-Stack, Ziggurat runs entirely on your computer and relies on the radio portion for simple packet sending and receiving. This removes practically all resource limitations from your Zigbee network, completely open sources the entire Zigbee stack end-to-end, and allows for complex bugs to be fixed more easily.
See the main ziggurat project for more information.
ZHA connects to the add-on through the zigpy-ziggurat radio library.
