| Omnibattery | Works Local | ESPHome driver reads RS485 bridge entitiesSaved copySupports the marstek-lilygo-rs485 firmware (whyisthisbroken): the ESP32 owns the battery's RS485 port and exposes the decoded v2 registers as ESPHome entities, so the driver reads hass.states and writes select/number services instead of Modbus. Reuses the Marstek logical keys verbatim (force_mode + set_charge/discharge_power, cutoffs, rs485_control_mode) so the existing entity, manual-mode and PD machinery work unchanged. - drivers/esphome.py: EsphomeEntityDriver + entity-name mapping table, resolved from the registry by slugified original_name (survives renames) - config flow: new "esphome" … Excerpt saved from GitHub on 2026-10-23. | PR #58 · 2026-07 |

In ReReHome
Once Home Assistant’s HomeKit Bridge shares it, this device reaches Apple Home as a HomeKit accessory behind your Home Assistant bridge, so ReReHome shows and controls it like any other.
