I bought as a test IR remote 433MHz radio remote. Chip is CBU i.e. BK7231N plus special chip for 433MHz I do not know.
At least IR part should be supportable.
Does anybody know this or got it to work?

Here is decoded firmware
{
"wfst_pin":"9",
"rf_study_feq":"0",
"owm":"1",
"rsthold":"3",
"wfst_lv":"1",
"netyc":"1",
"infrr":"8",
"netnc":"0",
"infre":"7",
"crc":"46"
}
Device configuration, as extracted from Tuya:
- WiFi LED on P9
- IR Receiver is on P8
- IR Transmitter is on P7
No module information found.
And the Tuya section starts, as usual, at 2023424
I also find that Button is connected to P23
