Hello, I installed the HA Fronius integration, however the display of Energy → Energy distribution seems to be wrong with a duplicated graphic?
Any easy guides to setup input/output rates and other nice graphs please?
Once I’m sure it’s correct, I plan to clean the solar panels to see any differences, but don’t want to lose any juicy data of the unwashed solar panels.
Please show what entities you have used for your current energy panel configuration.
Somehow, it shows 2 inverters, but I only have 1?
HA → Energy
HA → Settings → Devices & Services → Fronius
Here’s the devices: HA → Settings → Devices & Services → Fronius → 2 devices
Here’s the entities: HA → Settings → Devices & Services → Fronius → 22 entities
It’s all default, however I did enable some disabled sensors/entities. I assume all 22 entities are being used?
What I meant was the energy dashboard config. You find that at “Settings → Dashboards → Energy”. It seems you did configure the same entity for production and grid import.
What kind of smartmeter do you use? If it was a Fronius one (or S0 connected to the inverter) it should be listed in Fronius devices page.
Sorry, I’m new to it and must have messed it up.
I don’t know about Smart meters, so I probably don’t have one then?
Remove the entity from “Energy grid”.
This entity meters your solar production. not your grid consumption. You’d need an energy meter at grid interconnection point to measure that.
Fronius offers such for ~250€ + installation. You’d get that data in Fronius’ App and solarweb website too with that. In HA you can of course use other devices of different manufacturers / integrations too.
Done. Now I see just solar production.
I probably won’t buy another product for now, but I’m keen to see how the solar changes when I scrub them clean after over a decade of no cleaning.
My power company said I have a smart meter.
However noone knows the details, so I hope this image helps?
Also, I have real troubles connecting to the Fronius inverter.
I changed my Wi-Fi AP’s SSID, which disconnected several of my HA devices.
Connecting to the Fronius inverter is one of the hardest things as the instructions rarely meet reality.
I have followed these steps, but am unable to access the inverter’s settings to update the SSID to connect to:
Stand in front of the inverter → SETUP → Wi-Fi Access Point → Activate → Phone → Wi-Fi → FRONIUS_240.xxxxxx → Password: 12345678.
I reach as far as the phone connecting to the inverter’s Wi-Fi, but from there, I should be able to open a phone browser page to access the inverter and change the inverter from a Wi-Fi AP to a WLAN. Then the inverter WLAN will connect to my Wi-FI AP new SSID.
Maybe you can integrate the power companies smart meter via something like SlimmeLezer or some other device reading the optical port.
For the Fronius device, my recommendation is to use its LAN port rather than WiFi if you can.
Thanks for the SlimmeLezer suggestion.
The electricity company says it knows nothing about the Smart Meter, apart from knowing there is a smart meter with number xxxxxxxxxx.
No response with details, which I was hoping would help configure to HA.
I’ll hold off buying the SlimmeLezer, as I’ll need to contact a professional electrician to check if they will wire it in.
1st priority is to fix the solar input readings.
Fronius is terrible for support. If they had clear instructions, support would not be needed. Support typically says hire a solar electrician, however the problem is the inverter Wi-Fi connection doesn’t connect when it should, due to unclear intructions.
Fronius should have a digital webpage for versions correlating to exact steps, however Fronius tends to say hire a professional, which is unnecessary in proper Wi-Fi AP product set ups.
Ok, fixed HA so no duplications and new house Wi-Fi AP SSID reconnected.
Think I’ll open a new thread to setup solar view from just total kWh solar production, to showing live output and maybe some other nice metrics.
