    Hello,
    I have a problem with my two smart plugs, which have an LN882HKI chip, where I have to plug and unplug them countless times after a reboot until the devices are reachable on the network.
    This behavior seems to be related to the chipset, as the same OBK version on devices with a Beken chipset or BL chipset does not exhibit this issue.

    The configuration looks like this:
    //clearIO
    PowerSave 0
    Flags 134743044
    SetupEnergyStats 1 60 1440 1
    startDriver NTP
    ntp_setServer 192.168.1.103
    ntp_timeZoneOfs 2
    waitFor NTPState 1
    //startDriver TuyaMCU
    //startDriver tmSensor
    mqtt_broadcastInterval 30
    mqtt_broadcastItemsPerSec 30
    waitFor MQTTState 1
    //tuyaMcu_defWiFiState 4
    //tuyaMcu_sendQueryState

    Does anyone know what the cause is and how to fix it?
    How do I determine if the device isn't booting or if it's just a Wi-Fi connection issue?
    Can I reinitialize or restart the Wi-Fi using script commands without rebooting the device? When rebooting, the devices always briefly turn off the power. If the Wi-Fi could be restarted separately, this could implement a ping watchdog that doesn't cause a power interruption.

    EDIT:
    I also tried "PowerSave 1", but this makes no difference.
