Inverter integration of Invertech IS-050S

Not sure if I am in the right category:
I just got an Inverter from Invertech.
They seem to be a niche product as of now as not many ressources are available.It would be great to get some help on how to integrate the power measurement into HA.
I was forced to register a cloud account and in the App I have a Dashboard.
The App is called “Inver Energy” or “Minverter”
it looks like this:

I couldn’t find any webinterface on the device locally.
I know the IP and did a portscan but no luck. Any help is highly appreciated!

Hi,
I did some reverse engineering of the API calls and made an integration. So far it only recognizes power plants and inverters. Feel free to test it out.

Thanks for your efforts but as of now I get this:
2025-08-22 17:29:33.458 ERROR (MainThread) [homeassistant.setup] Setup failed for custom integration 'invertechs': No setup or config entry setup function defined.

The blured nickname is the one I see in the app.
Looks like the login worked.
__init__.py seems to be missing?

Sorry about that, I fixed it just now. It got lost somewhere.

Thanks a lot for your work. It looks better now.
2 things I noticed:
I am unable to integrate the live sensor to the energy dashboard.

The other thing is the naming:
All sensors contain part of my login Mail address. This is just a cosmetic issue.

Hi,
Thank you for trying it out.
You’re unable to integrate the live sensor because it reads values in Watts (W). The Energy Dashboard accepts only values in Watthours (Wh). This is intended HA behavior. All of the conditions for the sensors are met:

  • the domain of the entities is sensor
  • device_class is energy (for the live sensor it’s power)
  • state_class is total_increasing (for the live sensor it’s measurement)
  • sensors have their unit_of_measurement configured correctly

Naming of the entities for the Power Plant device is set according to the name of the Power Plant you set up in the app. If the name you set up for the Power Plant in the app is not the name you see in HA, let me know so I can investigate further.

thanks for the explanation,
yes my plant is the name used.
I like to use my shade automation with it and the inverter energy is the the sensor for the sun :slight_smile:
The only problem is the polling intervall of 5 minutes. can this be increased to 1 minute?

I noticed that some API endpoints can be refreshed more frequently than others, so it is possible. Only a few sensors (related to the Power Plant device) will be refreshed faster. This is an API limitation. For example: inverter details like temperature or power output of individual solar panel inputs can only be refreshed once every 10 minutes. Power plant information like total energy generation can be refreshed once every ~30 seconds.

I’ll look into it, thanks.

for my case the live watt output is interesting. In the app I can manually refresh the output fairly often.
Is there an official api documentation? I found nothing

There’s no documentation. So that’s just me guessing. I noticed that in the app as well.

Any news on the update interval?
