Suddenly TED stops to record energy readings
« on: February 25, 2018, 12:40:59 PM »
Hello

I recently faced a strange behavior in my TED Pro Home energy meter.

I was at home and nothing special occured on the electricity line in my house. The TED meter was working fine since two months and suddenly it stops to record the energy readings:

However, the real-time kW usage and overview system windows in the TED dashboard were in activity showing non nul real time data ALL the time. "Advanced/Restart TED Pro" menu (reboot) had no effect on this behavior. Power unplug the TED then power plug in allowed the meter to retrieve a normal behavior.

Unfortunatly I do not know to reproduce this issue.

May be you know the TED can have sometimes this behavior ?

I have seen this sort of behavior. Typically, for me, the time for one MTU would seem suddenly to jump forward by a few hours and the recorded values for the intervening time would be filled in by the sort of numbers you show. When the actual clock time caught up with the time that the MTU 'thought" it was, it would start recording correctly again. The ECC was eventually replaced and this solved the problem.

Typically when the same value repeats multiple times in succession like you're seeing it would indicate a PLC interference issue so there are some specific details that we would need to get about your installation and the best way to troubleshoot this would be through our ticket system so I will provide a link to do that below.

For troubleshooting or if you run into any questions please let us know by going to http://www.theenergydetective.com/ticket and fill in the requested information to submit a support ticket so we can work to resolve any issues that may arise ASAP and make sure we provide the right firmware for any updates requested or required.

The thing that (to me) is against this being a PLC issue is that the values being repeated are near (but not exactly equal to) zero, which is characteristic of the issue I saw and described. In the past, when I have seen problems from PLC interference, the last valid readings received have been duplicated. As you say, however, it needs a ticket.

Thank you all for your experience and advise.

I already wanted to get a plug-in noise filter and I just bougth one and will receive it soon. I have in stock an in-line noise filter. If the issue persists despite the filters I will place a ticket.
