Hi @Stephen2Aus and @MikeP, thanks for reaching out to us and it's great to see your interest in V2G/H!
We're just as excited as you are to get the ball rolling on bi-directional charging in our trial; unfortunately, as @David_AGL mentioned earlier, we have run into some complex tech and compliance issues which we are still working through.
At this stage I can't add a lot more I'm afraid, but I'm hoping to have a more substantial update in the next month or two as we work through the kinks ...
