need it since the regular sma plugin does not work with a datamanager

Describe the solution you'd like

like to install your plugin for the sma datamanager and like to measure the dc side of the inverter, such as the Core2 and tripower X

can u please add following:

Measurement.DcMs.Vol[0] ... Measurement.DcMs.Vol[11] Measurement.DcMs.Amp[0] ... Measurement.DcMs.Amp[11] Measurement.DcMs.Watt[0] ... Measurement.DcMs.Watt[11]

please, can u have a look and keep me posted.

Describe alternatives you've considered

reading the inverter trough modbus does not work and/or give wrong results

Additional context

i appreciated your work, tanx

hi, i need some more information to add the channels.

could you provide a screenshot of the instantaneous values page with a filter set for "Measurement.DcMs.Vol" (and the other three) The Name, Channel and Current Value fields should be visible. Example (but this should show values for you):

please also include some informaton what kind of device thsi data is from. Is this a solar inverter?

hi, this is a screenshot of the SMA EDMM-10 managing a SMA Tripower Core2 STP 110-60 which has 12 MPPT. the same is true on the latest SMA Sunny Tripower X. with your plugin i like to make a homeassistant dashboard where i can meassure/monitor the DC side of the inverter. i have allready been poking in your code and found a file custom_components/sma_data_manager/sma/known_channels.py where i add the missing channels without result.

file custom_components/sma_data_manager/sma/known_channels.py where i add the missing channels without result.

thats the main thing that has to be done, so if that didn't work there might be something more going on... Could you share the code you've added to the known_channels.py file so i can take a look?

on another note, are you able to see & enable the channels in the integration options page?

known_channels.zip

i have access to a SMA TripowerX, which has 3 MPPT's i've modified the mentioned file known_channels.py with 9 new lines. i restart ha, but i can't see the new enries in the pulldown menu: can u have a loop please? PS: if needed/usefull, i can give u access to my remote environment.

i restart ha, but i can't see the new enries in the pulldown menu:

are you able to scroll down in the list? Are there any values for Measurement.DcMs.Vol[x], Measurement.DcMs.Amp[x] or Measurement.DcMs.Watt[x] in the list?

---

if not, could you add some print statement (or similar) before this line: https://github.com/shadow578/homeassistant_sma_data_manager/blob/b8bebefb65c929308e23b39cfba19c6d121cd8b5/custom_components/sma_data_manager/config_flow.py#L322

please add print statements to dump both all_components and all_live_data in a way where the values are visible. you'll probably have to iterate over the entries with a for loop.

once you have the values, copy them over here

known_channels.zip

this is the modified known_channels.py file i'm not a python developper so i can't dump in a way where the values are visible. can u reproduce the testcase in your environment? many tanx.

[d01cid]

chris, sorry 2 disturb u, but did u had the chance for testing my modifications yet? keep me informed please.

Hi @d01cid ,

sorry for the slow response on my end.

I've since been able to replicate the issue (turns out my PR inverters also report these kind of values). i've created a PR that should add support for all the measurements you requested in the original issue, plus a few extra ones.

it would be very great if you could test the changes on your system before i merge them. to do so, please manually clone the repo into the custom_components folder of your homeassistant, selecting the add/array-channels-support branch.
