With my custom made devices I’m using custom data structures and ZigBee is used only as a data transport protocol. However, having more and more standard ZigBee devices available, I started to look for some standard ZigBee features implementation in Python. Unfortunately wasn’t really able to find anything which would fit the purpose – ZigBee feature implementation decoupled from manufacturer specific elements and covering ZDO\/ZCL processing\/parsing as per ZigBee standard.<\/p>\n
There are usually three groups of references coming up in search results:<\/p>\n
So I decided to look a bit more into bellows package. Quite quickly I was able to simulate parsing of ZCL\/ZDO messages, but few of the general concepts were not exactly matching my expectations. So to make it work for me either I had to implement EZSP uart protocol in my coordinator device, or rewrite several parts of library which would anyway require quite good understanding of ZDO\/ZCL stuff. Unfortunately neither was looking as a quick and simple option.<\/p>\n
The only option left was to dig into ZigBee ZDO\/ZCL details and create some kind of prototype library by myself to get better understanding what I can get out of standard features, the complexity of implementation, and then decide to have another look on bellows package or continue with own library creation.<\/p>\n","protected":false},"excerpt":{"rendered":"
