I took a couple of hours and a couple of 's and mocked up a DIY Zigbee light using the new M5Stack NanoC6 chip. You are able to code a complete Zigbee device using only the Arduino IDE. No need to have to used the more complex Platform I/O or Expressif IDE’s.
The ESP32-C6 chip is a very interesting device, in that you can use it to create a WiFi 6 device, Zigbee device or Matter device, by only uploading different software to the chip.
M5Stack does an excellent job of both hardware and software documentation for their products. And at an amazing price point of six dollars U.S.
Link to the steps I did to get this up and running is below. I still have much learning to do, however this short first pass shows the power of this ESP32-C6 chip and might give you a start to some interesting home automation ideas.
Another ESP32-C6 option to try, this one is sub USD 6 and has external antenna connection (or internal via software selection) and more pins broken out. Also looks to have some good documentation (2 deep sleep examples, how yet to see how these interact with Zigbee radio stack).
I’ve not revisited this code in some time, apologies for not being much help.
It’s looks like they made an update to this repository recently and the examples are missing for Zigbee. If you do a search within the repository, the older code is still there (power of github versions ). You might post a issue in the repository that they ‘86ed’ the examples. I note they have a whole bunch of new contributors to the repository. That said, I made a copy of this specific example to my repository, so you really do not need the original example, I had to make some changes to this code to get it work with the C6 and Zigbee2MQTT, hence why I made a copy.
All that said, my original modded code quit working a while back as noted by this issue (link below) posted to my repository. The author posted some fixes to make the code work with the newer revisions of the library, have a look at those to see if you can make progress. Good hunting!
