BK7231N Relay & BK7231T Drive Startup State Issue After Power Loss

Hello. I have a problem with two devices,
relay 16a and drive for ball valves that do not remember the state for starting activation.
Relay BK7231N, drive BK7231T in the Configure Startup settings is set to "- 1", but when the power supply is new, the drive always switches from one position to another, regardless of where it was previously, and the relay is always turned on.
Firmwares have been updated to the latest.
What else can you do?

Well, first I'd suggest to check if the channel value is retained or not.

When you have channel set to 1, and you reboot, does it return back to 1?

If you have channel set to 0, and you reboot, does it return back to 0?

The short time with the relay pin being in low state is unavoidable because device needs time to boot.


Or, are you really sure, that your Relay device always boots with channel set to 1? If so, then maybe you have something set in startup command?

The channels have been saved. I never wrote anything about running on these devices. I have always flashed and configured all devices the same way. However, these two devices simply ignore the behavior setting when new power is supplied.

Sorry for my text, I use a translator.

What can I provide so you can help me find out?

Can you please first disable MQTT and check if the problem persists?

There is not really much to check. You might have something in the autoexec.bat or in the short startup command.

Or maybe your issue is not strictly related to OBK? How your device looks like?

Are you saying that other devices are working fine?
