Openbk Installed Wifi Smart Switch: Connection Issues and Hard Reset Queries

I have a problem with a WiFi smart switch. I successfully installed Openbk on it, but after some days, it is not connecting to WiFi and not going into AP mode. The LED is always on. Is there a way to hard reset it?

Thanks

Nobody can help me? Thanks

This is the module and the led always on

I apologize, I haven't seen this post. Well, this looks like an unusual problem, but maybe the power supply of device is failing - try adding PowerSave 1 to startup command to reduce current usage. This will enable dynamic sleep while maintaining all device features.

Do you have latest OBK version?
Latest OBK version has both MCU watchdog and our own low-heap-panic system enabled, so it is surprising that it locks itself up.

When it locks itself up, are you able to ping it? Is it still available on DHCP clients list? Is it totally dead, or maybe just website is not working?

Thank you for the answer.
No, I can't find it on the DHCP devices list, so I think it is totally dead. Is there something I can do?

Is it still recognizable by the UART flasher? Of course, disconnect mains first before checking!

Did you use PowerSave 1 to save energy?

In some rare cases, the cheapest Tuya devices may require PowerSave 1 in order to work properly, otherwise capacitors can bulge. Are all the capacitors on the board ok?
