Preventing house battery from charging EV during intelligent octopus go charging sessions out of off peak times

Firstly I’m a total dunce using HA green. I downloaded the automations from bottle cap dave (thanks for that Dave). But can’t get the sensors to register when IOG chooses to charge my car outside of off peak times and turn my powerwall to 100% backup power thus preventing it from charging my legacy Tesla S whilst allowing cheap rate electricity from the grid to do so. I can see the sensors are there. The intelligent dispatching sensor remains off and the intelligent state sensor remains unknown. Anyone any ideas how to reconfigure them?
