Hi,

I have been dwelling with the integration of my Iammeter WEM3080 in Home Assistant. It was functioning fine in HA until it stopped suddeny. I have tried everything I could to resolve the issue including recently trying a fresh HA installation. Nothing seems to work. Iammeter app and web-app work fine.

My firmware is PM_20180919_3162_01, which I read on one of your responses is a pre-2018 hardware, not supported and not upgradable. But I bought the meter in 2020, as a WEM3080 (single-phase).

Why has it stopped working with HA? What can be done to resume usage as before (HA integrated)? What are my alternatives?

Thanks in advance for  your help.

Hi, if the firmware is 

 PM_20180919_3162_01

This single-phase meter is not WEM3080T , it is WEM3162, used a total different structure as WEM3080

Yes, it stopped production in 2018 .

And I remember we only support WEM3162 in the first core integration of HA, all other methods(mqtt, modbus/tcp, hacs) do not support WEM3162

I also do not know why it suddenly stopped working in your HA. Have you upgrade your Home assistant? if so ,it may be caused by this reason.

Home assistant usually introduce new limitation in upgrading that lead something available in previous version can not work correctly after upgrade .

In fact, you can try the self-customized interface.

the integration depends on the API of /api/monitorjson

you can try to parse this json format (the WEM3016 have different json format than WEM3080) by a Yaml file and it may resolve this issue.
