Is this a paper launch or did they stop working in the open? Just look at the dishwasher example[1]: It is a lazy copy of the Lamp example. They couldn't even be bothered to fix the title. The rest of the source code is as good as empty and was not updated in months. [1] https://github.com/project-chip/connectedhomeip/tree/master/...

They do have example Matter projects for the ESP32-C3/S3. I assume it's over WiFi and not thread. https://github.com/project-chip/connectedhomeip/tree/master/...

ESP32s aren't really ‘lower level’ in the sense that anyone is likely to write assembly code for them (compared to, say, 8051 or PIC), other than maybe some driver author at Espressif. The big win from using RISC-V, other than name recognition, is mainstream compiler support (which is nothing to sneeze at, especially when it's largely funded by someone else). When I worked on Matter¹, the Xtensa and RISC-V versions were basically fungible from the software point of view. (And really, so were other vendors' various ARMs.) We did find that Bloaty McBloatface² didn't support Xtensa, so I had to write an alternative. ¹ https://github.com/project-chip/connectedhomeip/ ² https://github.com/google/bloaty

Bloaty is a nice tool. When I worked on Matter a couple years ago, we had the problem that its backend http://www.capstone-engine.org/ did not support Xtensa, and produced some Python tools that could take output from bloaty or similar data from readelf or elftools, and produce several kinds of report. https://github.com/project-chip/connectedhomeip/blob/master/...

Matter was founded by Amazon, Apple, Google, and the Zigbee alliance. Apache-2 licensed. HA seems to embracing Matter/Thread pretty heavily. https://en.wikipedia.org/wiki/Matter_(standard) https://en.wikipedia.org/wiki/Thread_(network_protocol) https://github.com/project-chip/connectedhomeip https://www.home-assistant.io/skyconnect/
