SolaX Power issue with Energy dashboard - “Last reset missing”

[Cardo1]

Hello,

I’ve been using the SolaX Power device with the Energy dashboard for the past year or so and this was working fine up until some time in the past month. Now, the Energy Usage and Solar Production graphs, as well as Sources show the SolaX production as 0kWh. When looking at the config page for the Energy UI, it gives me an error stating:
“Last reset missing
The following entities have state class 'measurement' but 'last_reset' is missing:
sensor.solax_xxxxxxxx_today_s_energy“

There don’t appear to have been any updates to the SolaX Power service, and there’s certainly been no change to my very dumb inverter, so I think this started after a HA update.

For info, looking at the device within settings shows me all the relevant data, and I am able to display other bits of data in the Lovelace UI.
