SMA data not updating

The problem

SMA Entities not updating
I have a SMA Sunny Boy 6.0 with a Sunny Home Manager 2.0 (Both connected to my network via Ethernet, Wifi Disabled)
I have the ability to see power coming in and out of my main power lines of the house.

As of approx 3-4 days ago Home assistant stopped getting live updates and they only update when I manually reload the integration.
Clicking through some of the sensors such as
Inverter condition
PV Power
Electricity Export
Electricity Import
Current Power Draw (in Watts)

All normally update every few seconds however all these have a last update of over 3 hours (when I last manually reloaded the current configuration.) Its currently dark outside and the last update I have on my PV Power is that im generating 5.7KW of solar.

This occurs on Home assistant version 2023.9.3, 2023.10 and 2023.10.1

The SMA app shows all the correct (and updated) information aswell as the WebUI on the inverter.

What version of Home Assistant Core has the issue?

core-2023.10.1

What was the last working version of Home Assistant Core?

core-2023.9.3

Hello, I have the same issue with my SMA integration. For the past few days, some information only updates when I restart Home Assistant (for example: Total Yield). However, "Daily Yield" updates correctly.

Hello, I don't have any issues this morning. Everything seems fine now.

same Problem like OP here. Some values updating, some only one time after HA restart once and after this no more value updates.
Problem exists since latest HA update 2023.10.1

I am experiencing the same issue. In the logs I found the message ValueError: Sensor sensor.kraftwerk_grid_power_factor_excitation has device class 'power_factor', state class 'measurement' unit 'None' and suggested precision 'None' thus indicating it has a numeric value; however, it has the non-numeric value: 'Overexcited' (<class 'str'>). After disabling this sensor, the other sensors update normally.

thanks. works for me ✌️

Thanks for looking into this @bajansen

I assume this SensorEntityDescription is incorrect:
https://github.com/home-assistant/core/blob/dev/homeassistant/components/sma/sensor.py#L274-L281

I expect removing lines 277 and 278 will fix it.

        state_class=SensorStateClass.MEASUREMENT,
        device_class=SensorDeviceClass.POWER_FACTOR,

I will see if I can validate this and propose a fix.

Legend. Disabled this and instantly all my values starting updating.
To save some time, other looking for this, its under "Diagnostic" entities
