tools/generate_grafana_ups.py writes grafana-ups.json, which shows the JBD network UPS, the River 2 desktop UPS, and the River 3 NAS UPS in three columns. Git ignores the generated file. Each EcoFlow column shows one time-remaining panel in hours, for the direction in use. The River 2 histories add pack current and remaining capacity. The River 3 reports neither, so its histories add battery power and charge.
