Hey,
I bought some LYWSD03MMC devices and thought to flash them with custom firmware. However, the https://pvvx.github.io/ATC_MiThermometer/TelinkMiFlasher.html doesn't recognize the devices properly (I tested with only one but asusme that all have similar firmware inside.
On Google Chrome (121.0.6167.189) with enable-experimental-web-platform-features enabled the page says "No compatible devices found". Then I tried Microsoft Edge (122.0.2365.59) which found the device but as a unknown or unsupported.
Selecting the device says "Connecting to: Null and then nothing happens.
I connected the device to Xiaomi Home app and below is the device information. Not sure if the firmware on the device is so old that it's not recognized. The Xiaomi app has firmware update (2.1.1_0159) for the device but that would block OTA updates.
