I wondered if anyone else was experiencing the following phenomenon with SDM120 or other eastron meters over modbus:
Half of my meters on the same network appear to be cycling continuously whenever the USB adaptor is connected. I have tried with two emonPI’s so seems local to the meter. All meters appear to be running the same firmware version. Unplugging the OEM adaptor and the meters resume normal behaviour.
Besides that, emonCMS is accepting data nicely from all meters using the MinimalModbus interfacer and OEM’s modbus adaptor. So not a problem per se but doesn’t seem right with meters continuously rebooting (assuming they are).
Nothing from Eastron support yet, and wondered if others had experienced the same or had thoughts on the root cause - or a batch issue…
