Hello everyone
I would like to make our new solar system as “smart” as possible and since there is an integration for Fronius products for HA, I have set up a corresponding system.
My problem now is as follows: I have two Fronius inverters: a Symo Gen24 and a Symo 3.0-3. There is also a Fronius Smartmeter TS 65A-3 installed in the fuse box. The flows are also displayed correctly in the Fronius app. Unfortunately not in Home Assistant.
I would simply like to know: current total production of the solar system, current total consumption, current grid consumption.
The Fronius integration finds two devices:
SolarNet, Fronius, fronius-datamanager-card
Symo 3.0-3-S (1)
I can read out the current output from the Symo 3.-03. However, I have no access to the data of the second inverter or an overall view.
Shouldn’t the TS 65A appear as an independent device in HA in my configuration? And if it actually has to do this: where could I start troubleshooting? Could it also be that the solar company has configured something incorrectly or less useful?
It’s difficult to say in detail, as I don’t know how such a Fronius system would normally have to present itself.
But what I can see: Both inverters are connected directly to my switch via cable and I also see two Fronius devices in my network.
When I enter the first IP address in the Fronius integration, I get the result I already posted (the Symo 3.03 and the SolarNet datalogger). When I enter the other IP in the Fronius integration, I only get an error message (“Connection failed”).
So I suspect that the Gen24 inverter is “unreachable” for Home Assistant for some reason.
(I just don’t understand how this is supposed to work at all: The smart meter would have all the information I would need, right? However, it communicates with the inverters via Modbus and doesn’t have its own network connection - so it would have to pass on all the data to the Fronius servers via one of the two inverters. At what point could I access the data?)
OK, I just opened the second IP with a browser (… yes, I could have thought of it earlier…) This is the Gen24 inverter and it also supplies all the required data via the local web interface. So far, so good.
A look at the help description then gives the note “For Gen24 devices (delivered with Firmware >= 1.14.1) make sure to activate “Solar API” in the inverters web interface.”
Unfortunately, all menu items for configuration are locked and I don’t have any login data (is that normal? I bought the boxes after all!?!). So I will contact the installation company and make sure that the “Solar API” is activated. Maybe the problem will be solved by then.
Login to the inverter has 3 default users, customer, technician and support Any can access the API setting (Communication/Solar API). Your installer should be able to activate it remotely (but should have provided customer login, at least).
It is off by default but must be enabled for data access without authentication (ie IoT devices & home automation).
Ah, sorry. I missed that one was Gen24. These afaik can’t be connected via SolarNet. They always have their own (integrated) datamanager - thus their own IP and you need to activate SolarAPI and add the Integration in HA for each inverter.
The Meter is connected to one inverter via Modbus. Its data will be available via SolarAPI through that inverter.
