Closes wildekek#8. Replaces the blanket update_interval: 5s with a 1s base poll plus per-entity skip_updates so that: * dynamic measurements (Output V/I/W, Battery V/Ah/Wh) refresh every 1s — fast enough to see a load step transient in HA * thermal & input-rail sensors refresh every ~5s * static identity (Model/Serial/FW version) every ~60s * config setpoints (OVP/OCP, Backlight, internal date_*) every ~30s * fault flags (CV/CC, OVP/OCP) and the Output switch stay at 1s The base interval is exposed as ${update_interval} in the substitutions block so users can dial it down (e.g. "5s" to restore the old cadence) without touching individual entities. At 115200 baud each Modbus read is ~3ms, so even with all entities polled simultaneously the bus is well under saturated. RD6006 firmware handles ~5 reads/sec comfortably; we end up well below that since slower entities skip most cycles. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Replaces the blanket
update_interval: 5swith a 1s base poll plus per-entityskip_updates, so dynamic measurements refresh every 1s while config / static / setpoint entities slow down to once per 5s, 30s, or 60s as appropriate.The base interval is exposed as
${update_interval}in the substitutions block — set it back to"5s"to restore the old cadence with the new per-entity proportions intact.Cadence summary
Battery modestays at 1s (no skip_updates) because the battery_charge / battery_energy availability gate (#17) consults its state on every poll; slowing it down would let stale Ah/Wh values leak into HA statistics on transitions.Verification
