The zmai90v1 sensor platform allows you to use ZMAi-90 energy meters sensors with ESPHome.
This page refers to version V1 (V9821) of the
ZMAi-90, which has been out of stock for a while. For using the newer V2 (TYWE3S) see zmai90.yaml or for V3 (WB3S) look a solution here (use external_component source github://dentra/esphome@tuya-raw-fix-standalone) and please vote for PR to include patch to ESPHome.
