Sensors missing in HA 2023.11.3 with 1.6.2

[tomkiss]

After upgrading to HA 2023.11.1 and installing the Intelligent Octopus integration through the dashboard, there appear to only be two sensors available, "Octopus Intelligent Next Offpeak Start" and "Octopus Intelligent Next Offpeak End".

Any ideas how to get back binary_sensor.octopus_intelligent_slot?

Checked the logs, and can see the following error:

I can see others have had this problem in the summer, which was fixed for them in v1.6.2, so I'm not sure what I'm doing wrong here. Will keep poking...
