I haven’t seen an update on this. Your own advertising mentions how tiered rates are important for monitoring but I can’t set my rates intelligently.
I’m in Ontario, Canada and we have two sets of tiered rates based on time of day and season.

Aside: even my Chevy Volt PHEV knew how to do seasonal tiered rates back in 2018 or earlier.
