Partial The ESPHome YAML and custom component are vibe-codeable, but the product depends on ESP32 hardware wired to the meter's P1 port and on decoding the Israeli Kaifa meter's DLMS/COSEM telegram format.
What it would actually take: A real version needs ESP32 firmware built on ESPHome, with a custom component that reads the serial telegram at the meter's baud rate and parses DLMS/COSEM OBIS codes into power, energy, and cost sensors for Home Assistant. Electrical wiring to the P1 port and some protocol reverse engineering for Israeli-specific fields are required. A builder needs basic electronics and hardware testing, but not deep specialist expertise.
