Hi, I have this 2 gang LSPS5 switch (BK7231N) There’s an issue whenever I toggle button 1 to turn off the relay, it reboots the switch like this I have swapped the chip with esp and the same thing still happens. I suspect there’s something on the pcb that’s causing this. Anyone have any...

First I would try with better power saving, in OBK it's PowerSave 1 command. I had already report about similiar problem and PowerSave helped.

@p.kaczmarek2 i’d like to add this just happened recently after using it for almost a year. No issue with other switches though. And only with button 1 (pin 14), no issues if toggled with button 2 (pin 24)

So, did you use PowerSave 1 on this device or not? Added after 44 :This is what happens if you don't use PowerSave on device with cheap power supply: Power supply low ESR capacitor degrades more quickly and device becomes unstable.

@p.kaczmarek2 no i’ve never enabled power save on this switches I’ll try when i get home So those capacitor issue is somehow related to button 1 when it’s toggled?

PowerSave 1 should be always enabled. It would have been enabled for default, if not for those few strange reports saying that it breaks something (it was a year ago so I am not sure). It also breaks IR and BL0937, but apart from that, PS should be good. I think it may be capacitor related. I would need to see the power supply. Is the capacitor bulged there? Check out photos from my article.

Hi, I have this 2 gang LSPS5 switch (BK7231N)

There’s an issue whenever I toggle button 1 to turn off the relay, it reboots the switch like this

I have swapped the chip with esp and the same thing still happens. I suspect there’s something on the pcb that’s causing this.

Anyone have any thoughts on this?

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:
