When monitoring steam, the production analyst claims there' 0 entities in a sandbox with the realistic fusion power. I have over 666 steam engines that have increased priority (power priority mod) and an input of 100C steam, which allows them to work at 50% efficiency. I also have high capacity turbines consuming 500C steam that's preheated (steam preheating mod) and high capacity turbines consuming 500C from normal high capacity heat exchangers. Please increase the scope that steam consumption searches for.

Thanks for the report. PA makes use of the products_finished property in order to monitor entities' consumption in a fairly UPS-efficient way. Unfortunately, this property only exists for crafting entities (that's assembling machines, furnaces, and rocket silos). Consumption by any other entity type, like ammo turrets, reactors, or generators (presumably the entity type of the steam engines you're using) is therefore not supported.
