Just did update and now cannot connect

[sydrooster]

Bit lost and desperate for help. I just tried to update the Sigenergy ESS via HACS from 1.2.0 to 1.2.1 and now everything is broken. I'm not sure if HA also updated its version there were a few updates, i only update every few months. Everything has been faultess since i setup a few months ago and have dashboards galore.

I just get the error"

"Sigen Plant
Failed to set up:
Check the logs"

In the logs it contains:

---

Source: config_entries.py:751

The above exception was the direct cause of the following exception:

I'm not the most savy with this stuff but can usually follow guides well enough. There are a few other errors but this appears to be the main one. Hope someone can help.

Thanks

Hi @sydrooster — this is a Home Assistant version compatibility issue, not a problem with the integration. The UnitOfApparentPower.KILO_VOLT_AMPERE constant used by the integration was added to Home Assistant over 8 months ago, so your HA installation is significantly out of date.

Please update Home Assistant and the error should be gone.

OK, thank you. I had been dreading moving to DSM 7 so now that nightmare begins.
