Add heartbeat floor to Reduce DB Reporting ambient sensors - #105
Conversation
The reduce-gated ambient sensors (ESP temp, LTR390 light/UV) used a hardcoded delta with no time floor, so with Reduce DB Reporting on they could freeze and never show a value on boot. Give them a delta-OR-hourly-heartbeat floor and publish the first post-boot reading. Radar filters, BME280 pressure, and the toggle-off path are unchanged.

WalkthroughESPHome sensor filters now track initial publication time and NAN/non-NAN transitions. Reduced reporting publishes temperature, LTR390 light, and LTR390 UV values on first use, threshold changes, NAN-state changes, or hourly heartbeats. ChangesSensor reporting
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The PR adds hourly heartbeat reporting for reduced ambient sensors, but a first-sample timing edge case could cause one duplicate report when the device timer is zero. This is a bounded correctness risk that should have explicit owner awareness or follow-up before merge. Poem

current NAN state differs from the previous NAN state, while preserving the
hourly heartbeat and existing thresholds (5.0 for temperature, 20.0 for LTR390
sensors); apply the equivalent state-change logic at all three sites.

The isnan(last_reported_value) first-publish check had two failure modes once a sensor read produced NAN: the failure was hidden until the hourly heartbeat, and after the heartbeat published NAN every subsequent reading bypassed the delta filter, reverting the sensor to full-rate reporting. Use last_report_time == 0 as the first-publish check and publish immediately when the reading transitions into or out of NAN, in all three Reduce DB Reporting lambdas.

- Around line 412-416: Replace the last_report_time == 0 first-publication test
with a separate has_published flag in the affected ESPHome filters, including
ESP temperature, LTR390 light, and LTR390 UV. Initialize and update
has_published whenever a sample is accepted, including both reduced-reporting
and toggle-off branches, so a publication at millis() == 0 is not treated as a
second first publication.

What does this implement/fix?
Companion to the MSR-2 fix for ApolloAutomation/MSR-2#70. MSR-1 uses a BME280 (not a DPS310), and its pressure channel is not reduce-gated — but its other reduce-gated ambient sensors share the same "hardcoded delta, no time floor" pattern that can make a sensor look frozen when Reduce DB Reporting is on.
