Fix ESPHome sensors missing from the Home Assistant Energy dashboard: device_class, state_class, W vs kWh, total_increasing resets, statistics errors, integration sensors and broken history.
ESPHome pulse_meter vs pulse_counter for electricity, water and gas meters: low-flow accuracy, debounce, pulse totals, conversion formulas, ESP32 PCNT limits and working YAML examples.
Connect an Eastron SDM120 or SDM630 Modbus energy meter to an ESP32 and Home Assistant using ESPHome, RS-485, verified register addresses and import/export kWh sensors.
Quick Summary (TL;DR):There is no single “best” ESP32 energy-monitoring method because the four common approaches solve different problems. A pulse reader is the cheapest and safest way to read whole-home energy from an existing utility meter; its accumulated kWh effectively…
Quick Summary (TL;DR):An ESP32 can turn an RS-485 Modbus energy meter into a completely local Home Assistant energy monitor. For single-phase circuits, an Eastron SDM120-M/Modbus-class meter is one of the easiest DIN-rail choices; for three-phase, solar, EV charging or more…
