    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?

    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
