Iotawatt rebooting every 61 seconds

Morning Folks,

I have two Iotawatts in operation. Both have worked flawlessly for some months until about two weeks ago.
One is now rebooting every 60 seconds or so with the log entry below repeated with each. I see the reason being “Software Watchdog” but what is causing this and how do I fix it?

Thanks, Mike

Hi Mike,

I suggest The IoTaWatt forum is a better place to ask your question, as it seems that it is specifically about the operation and use of IoTaWatt. That is managed by Bob Lemaire, its creator, and he and the other users there are more likely to have the specific knowledge to help you.

The IoTaWatt forum uses the same software as this forum, but you must register a new account there. If the user name you have here is not taken, it might be helpful to have the same user name in both places.

If you post your question there, I’m sure he or somebody will get back to you quickly.
