A collection of Matter devices i've built using esp-matter SDK for esp32 family SoCs.
Important: these are quick cheap and dirty 'working enough' implementations built on top of SDK samples, so consider them more like a source of useful insights, than ready to use polished products.
Extended Color Light device for RGBWW strips, port of my HomeKit lunalamp-esp32. Transforms Matter XY/CT colors into RGBWW and uses LEDC PWM with external MOSFETs to drive a 12v led strip.
Makes a Matter pressure and temperature sensor from an aliexpress water pressure sensor known as KY-3V3-IIC or KY-3V3-I2C, this one:
Although the sensor indeed does report temperature, i would not rely heavily on it - i guess there are reasons it is not advertised as a pressure AND temperature sensor
A Matter 1.5-introduced chime device using ESP32 8-bit DAC or I2S PCM-to-PDM to output a small wave file. Crude and requires trickery to use with Home Assistant.
DAC is available only on ESP32, PCM-to-PDM is available virtually everywhere.
DAC can be used if you have a way to amplify the analog signal (e.g. a TDA IC), or you can try using PCM-to-PDM with a small gate charge MOSFET like AO3400.
If using Windows, the most troublesome part is setting up the esp-matter SDK itself — since esp-matter is basically an abstraction over the CHIP SDK, native Windows build is not supported.
WSL2 is fine, but you have to store esp-matter inside the native linux fs — Windows to linux fs passthrough won't work.
If you want your device to have a non-generic vendor, name and a unique provision QR-code — follow the instructions here https://github.com/espressif/esp-matter-tools/tree/main/mfg_tool
