    Nice, since you'r at it, maybe also change ntp_eventsTime type to time_t?
    Helpful post? Buy me a coffee.

    O.k., I added a second version of drv_ntp_events.c.
    No more casting for "gmtime", but now for the calculations ;-)

    Please note, since I don't use NTP, I could only test, if it compiles...

    The W800 does not compile:
    Code: text Expand Select all Copy to clipboard
    
./bin/build/w800/lib/libuser.a(json_interface.o): In function `$t':
(.text.JSON_ProcessCommandReply+0x916): undefined reference to `NTP_IsTimeSynced'
./bin/build/w800/lib/libuser.a(json_interface.o): In function `$t':
(.text.JSON_ProcessCommandReply+0x916): relocation truncated to fit: R_CKCORE_PCREL_IMM26BY2 against undefined symbol `NTP_IsTimeSynced'

    I guess this may be because you need to respect OBK_DISABLE_ALL_DRIVERS define which, if enabled, means that NTP_IsTimeSynced is not present in the build.

    Nice, but I am not sure about the if conditional for StartupUTC - what happens with Tasmota control if that field is missing from JSON?
    Maybe change if to work in such a way that if value negative would be to happen, then plug 0 so it prints 1970-01-01 etc etc? So just a clamp, but still add JSON key.

    Sure, fair point. Just changed this code once more.

    I was already asking myself why there are so many "fake entries" in this code (always reporting fixed strings but actual values ...) ;-)

Topic summary

The discussion revolves around the Elivo LSPA9 Smart Plug, which became unresponsive after an upgrade from OpenLN882H version 1.17.506 to 1.17.515. Users reported that the device initially functioned well with energy monitoring but encountered issues post-update, including slow web interface access and eventual unresponsiveness. Serial logs indicated recurring hardware errors. Various users suggested testing intermediate firmware versions to identify the problematic update, leading to the discovery that version 1.17.513 caused the issues. A workaround was proposed by disabling certain drivers, and a fix was implemented in subsequent versions, restoring functionality and stability to the device. The final resolution involved modifying the handling of time synchronization to prevent the device from freezing.
