CLIMATE_CONSUMED_HREFS (power, current/target temp, fan, swing, preset)
were bound as no-entity coverage capabilities with the Capability
default poll_tier='cold'. The coordinator only OBSERVE-subscribes and
sub-polls 'hot'/'warm' hrefs, so cold-tier state only refreshed on the
~30s full /device/0 summary sweep -- matching the 20-30s HA lag reported
on issue #17 despite commands landing on the device instantly. Pin them
to 'warm', same as CLIMATE's own primary href, so they get push
notifications (or warm-tier sub-polling as a poll-only fallback).
