I have to admit. The WDT reset is back even with 4.2.3 firmware.
It started last week with 4.2.5 and now with 4.2.3 as well.

Any solutions?

Only thing I can do is replace the OTGW with a spare one to see if this fixes the problem.

Re: OTGW hangs with WDT reset!

Since october last year I had some problems with the OTGW.
In addition when monitoring the performance of the central-heating system I did see some strange things regarding the boiler temperature suddenly dropping.
The result was sometimes no hot water after 5 minutes, and in addition WDT Resets with no root cause mentioned in the log.

I automated the reset switch but this is ofcourse no solution.
In the end around Christmas we had a broken pump.

A guy came over to fix it and he also noticed the rootcause problem of the cold water after 5 minutes.
He replaced the pump and several new boiler sensors. After that no more WDT Reset,
Strange or what?

Could it be, and I already attached the log files earlier that OTGW Firmware receives 'corrupt' data from the boiler sensor and crashes with a WDT Reset no cause?

Let me answer my own question :) .. that would be a NO.
Still experiencing random resets..... and hangs...
As I have automated the reset... it will reboot the OTGW after 5 minutes and it continues to work.
This happens around 7 times a day.
