Bulb reboots randomly and sometimes changes to the default green

[lexi-the-cute]

I've been trying to figure out why it keeps resetting and attempting to resolve it. It does seem to happen less often when not using the DDP / WLED effect

this is my ESPHome config

MQTT is locked down so you have to be authenticated to read or write to the topics, homeassistant/#, esphome/#, and iot/#. the iot topic is where i have my bulb prefixed to with the command topic being iot/lexi-room-bulb-1/light/lexi_s_room_bulb_1/command

This is the latest device info from the debug component above

When I still had DDP enabled, it was causing segfaults. I'm currently trying to get QEMU running with ESP8266 (and also will be messing with ESP32, but that's more for wanting to create my own devices in the semi-distant future to do custom things) so I can get a more in depth look as to the cause of the random reboots

The reboots happen anywhere from a few minutes to few hours. This issue has stuck around through multiple builds and changes of the ESPHome config, so it isn't likely to just be a bad build, but something else. Potentially corrupted data outside of the firmware, but I currently have no way to check that

This is the exact bulb I bought https://a.co/d/6JRLZgg

It just rebooted again while I was closing the issue (with the default green)

What's frustrating is, I bought 2 bulbs at once. One bulb just stopped working entirely out of the blue and this one has this problem. Hopefully the replacement for the completely broken bulb works fine and that it's just a bad batch

[lexi-the-cute]

it may have been light_restore_mode: ALWAYS_ON. will have to do further tests

[lexi-the-cute]

i think the first two bulbs were just a bad batch. bulb 1 is still misbehaving, but bulb 2's replacement seems fine

[lexi-the-cute]

looks like disabling light_restore_mode: ALWAYS_ON just masks the issue. the home assistant logs shows that the bulb still reboots itself due to "External System" even when it visually doesn't look like it changes. the replacement bulb for the one that just straight up died doesn't appear to be having any issues according to the home assistant logs. looks like i just got 2 bad bulbs in the same order. leading me to think the bulbs were not designed well when it was just really bad luck

[lexi-the-cute]

sigh

[lexi-the-cute]

in my attempt to debug this in QEMU, i attempted to convert this over from ESP8266 Wi-Fi to ESP32 Ethernet and came up with this cursed config. it fails to compile due to expecting the header file for ESP8266 Wi-Fi

so, at this point, i just hate these lights. even the replacement for bulb 1 is resetting on me and im just like, why? like it shouldn't be happening this much. these are 3 bulbs out of 4 that have turned out to be bad. only 1 of them has worked properly and they have been running the same ESPHome firmware
