A new Remote Meter card in the Accessories tab, next to Generator Setting and Solar Setting. One EMS binds two meters at most, so both are laid out at once — no meter dropdown. The card shows what each meter reports and lets Service read and write its six CT channels remotely. P0 scope: information + CT configuration.
Static demo with sample data — reads and writes are simulated in the browser, nothing leaves this page.
Layout note: with at most two meters there is no selector and no "switch meter with unsaved changes" rule.
Stacked gives the CT table full width; side by side fits both meters on one screen but needs a dialog for
the table, which also gives Cancel / Set a natural boundary. With no meter bound the whole module is absent — no card, no placeholder.
Assumptions beyond the PRD: a read against an offline meter is answered from the last cloud snapshot and Set stays
disabled, since the EMS cannot be reached. Read refreshes both meters in one request; Set writes one meter at a time.
Installation Purpose and Meter Name are shown read-only (open questions #2 and #4).
