{ "vendor": "Tuya", "bDetailed": "0", "name": "Full Device Name Here", "model": "enter short model name here", "chip": "LN882H", "board": "TODO", "flags": "1152", "keywords": [ "TODO", "TODO", "TODO" ], "pins": { "0": "LED_n;0", "3": "Btn;0", "7": "BL0937CF1;0", "10": "WifiLED_n;0", "11": "Rel;0", "12": "BL0937CF;0", "19": "BL0937SEL;0" }, "command": "", "image": "https://obrazki.elektroda.pl/YOUR_IMAGE.jpg", "wiki": "https://www.elektroda.com/rtvforum/topic_YOUR_TOPIC.html" }

To Reproduce Steps to reproduce the behavior:

1. Power up device, on homeassistant notice the correct mqtt data
2. wait ~ 2 hours
3. look again at homeassistant, notice all data is unkown, the uptime value stopped at ~2h
4. go to device web page, no response
5. look at router webpage , device offline
6. go to physical device, press button, no response
7. perform power cycle of device, now its running again.

Additional context Add any other context about the problem here.

• the data was originally published every ~3seconds, which i found was alot. so i set command VCPPublishIntervals 60 60 to get updates every minute
• the device was flashed via uart following this guide the only difference is i had to change the programming baud rate to 115200, a FW dump was also made prior to flashing
• i will attempt to leave the web application page open with the logs tab open to see if theres any usefull logs when the device becomes unresponsive

I just did a quick read through and i cant say for sure the issues are the same. In that post is seems to focus on the webserver being slow after 30seconds and then being unresponsive. That is not my case.

The post does say they have a PR in progress so i will keep an eye out for a new release to see if there is any difference.

Have you seen this? https://github.com/openshwprojects/OpenBL602/commit/c73dcaab7e73ab68b29bd20a3b5d4c0992902c1d Maybe I can backport it to OpenLN882H? https://github.com/openshwprojects/OpenLN882H/commit/15fde0f403e408eab6ffa31d0e5711e97c37afe2 Can you wait for next release (in 5 minutes) and check new binary?

i just installed the LN882H_1.17.518 via OTA. i will report how it turns out.

digging deeper in the uptime information on the device and i noticed that both times it happened at 2am (EST time) not sure if this means anything. on the main web page, it also says

NTP driver is not started, daily energy stats disbled. Periodic Statistics disabled. Use startup command SetupEnergyStats to enable function.

i dont currently need energy stats so im leaving it as is.

Hi just a quick feedback, So the plug worked for about 20h then it froze the same way again. (*.518)

I rebooted it and its been up for a few hours.

i just updated to *.522 as i see there has been somes changes on the LN882, ill report if theres any improvements

[geniusled]

the device has been up for a few days now with 1.17.522, so it seems the original issue has been resolved. it seems that the uptime sensor was a bit slow updating since then but thats not an issue for me. i just updated to 1.17.529 , ill see if this changes.

ill close this issue for now. Thanks you for the efforts of this project.

Sorry to bring this up again. The device lasted for 2 days until it crashed again on 1.17.529

The device is inconveniently monitoring all my network stuff (nas,wifi,router,etc) so its quite inconvenient to power cycle it/reset.

would there be an option for a long press reset from the button?

Devices have been relatively stable since, closing
