    I buy 3 power outlet to check if some I can apply tuya cloud cutter, no success
    2 of them its CB2S and one its WL2S, all of them with BL0973
    I read the tutorial and apply the fw LN882H.
    No MQTT, just standard config
    Code: JSON
    Log in, to see the code


    I have a weird operation with this module.
    its really slow, sometimes the ping its high, I try to change mac adress, because its started with 00:50:xxxxxxx, I never saw something like that.
    But the web admin its quiet slow, sometimes I loose the connection etc.
    I add the mqtt to test, same, i publish and takes time to read, and sometimes did not do.


    Any ideias?

    which guide did you follow, which tool did you flash with?

    does the mac at the bottom differ from or match (the latter part) the name at the top?

    I think this is still the case

    as for the poor wifi, this sounds familiar. I feel like there have been reports of such with LN882H for a few months.

    I'm not at home right now. I'll do some tests at night

    I use Python to dump and the .exe to write the FW.

    MAC looks like you sent me, the random.
    Mine is a power outlet.

    I changed the MAC to tuya athom standard and still there

    4C:3A:93:19:38:C3

    also look the ping, its weird and when I toggle, I loose the connection, I'm beside the router.

    The last screenshot shows weak signal.
    Do you maybe have more than one access point with the same SSID?
    LN882H is known to sometimes connecting to any AP, not the nearest. It's some time now, I once tried a solution, but didn't succeed, don't remember the last state...
