From 561207b1e2ec046e9978524255bd2b308c76e3c9 Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Wed, 8 Oct 2025 12:19:18 +0000 Subject: [PATCH 1/4] Initial plan From 38ff8612569a2932a7b4e748906d92a32ace4f49 Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Wed, 8 Oct 2025 12:30:22 +0000 Subject: [PATCH 2/4] Fix: Swap electrical and thermal sensor IDs in COP calculation The sensors were being used in reverse - the sensor labeled as "electrical" was actually measuring thermal energy output, and vice versa. This caused: - Energy consumption bars to show incorrectly high values (showing thermal as electrical) - COP calculations to be inverted (showing < 1 instead of 3-5) The fix swaps which sensor ID is used for electrical vs thermal calculations in useOptimizedCOPData hook.

This commit properly swaps which sensor ID is used for which calculation: - thermalSensorId data is now used for electricalEnergy calculation - electricalSensorId data is now used for thermalEnergy calculation This fixes the issue where electrical bars were showing as much higher than thermal bars (should be opposite for a heat pump with COP > 1).
