More info from the smart meter?

[bows33r]

Is it possible to get out more info from the smart meter then just the power of the phases?

I would like to get voltage and current also

I thought this would be https://github.com/bohdan-s/SunGather/blob/main/SunGather/registers-sungrow.yaml#L299 onwards for voltage and https://github.com/bohdan-s/SunGather/blob/main/SunGather/registers-sungrow.yaml#L1345 onwards for current 🤔?

No they only shows a value when the solar panels is producing energy :(

You are right for the current, but voltage works always:

hmm not for me :o

You can’t read the smart meter directly, only via the inverter. Some models of inverter don’t have all the registers available when they are not in run mode :(Sadly there isn’t much you can do unless you connect your own modbus hardware to the smart meter directly to read the values. Regards,BohdanOn 12 Jan 2023, at 5:14 pm, bows33r @.***> wrote: hmm not for me :o

In case someone is interested, the following registers hold power in watts for each phase. Only tested on SH10RT, so I don't know if it will work for other models:

- name: "phase_a_power"
  level: 2
  address: 5603
  datatype: "S32"
  unit: "W"
  models: ["SH10RT"]

- name: "phase_b_power"
  level: 2
  address: 5605
  datatype: "S32"
  unit: "W"
  models: ["SH10RT"]

- name: "phase_c_power"
  level: 2
  address: 5607     
  datatype: "S32"
  unit: "W"
  models: ["SH10RT"]

Found that, too.

Additionally there is another one for the total power:

- name: "meter_total_power"
  level: 2
  address: 5601
  datatype: "S32"
  unit: "W"
  models: ["SH5.0RS","SH3.6RS","SH4.6RS","SH6.0RS","SH10RT","SH10RT-V112","SH8.0RT","SH6.0RT","SH5.0RT"]

And I can confirm that its working (at least on the SH10RT) with DTSU666.
