Hi
I have a Huawei inverter hooked up by modbus tcp, and connected to the inverter is a Huawei meter.
Nymea connects and I see the inverter and the power meter too. The inverter meter looks good but the power meter doesn’t show total acquisition or total return (both are zero). The real-time data is fine. The energy dashboard graph of ‘totals’ is also missing these .
The Huawei app does have this data as a total (not a daily total).
How can I debug this further ?
Thanks
Hi @frankenbubble - please open debug interface (Menu - system settings - developer tools) and under the log tabs enable huawei and read the data for a few minutes. If you find some obvious error message, pls post it here.
What nymea server version are you using?
Hi Simon,
These are the logs with all the huawei options set to debug, server is 1.8.1+202306071550~lunar1 , the fusion.solar app says 12.98 kWh positive active energy (to the grid), and 147.46 kWh negative active energy (from the grid) when I took this log snippet , all I can see in there is – Read “Power meter active power” register: 37113 size: 2 – I don’t see it trying to read totals for example.

reading the code, looks like it wasn’t implemented, so not broken .
Yeah seems to be not implemented.
I can’t remember why, but I guess it had a reason back then.
I guess this information is not exposed on ModBus TCP.
I submitted Huawei: smartmeter add totals by frankenbubble · Pull Request #154 · nymea/nymea-plugins-modbus · GitHub , you need to look closely to see it working as its not very sunny yet today
