# **CIRCUTOR CVM-BD Power Meter / Analyzer ESPHome Integration**
The CVM-BD Power Meter is a programable measuring instrument
supports RS485 Modbus Protocol communication.
## **Requirements**
- ESP32 device with 320KB RAM, 4MB Flash and RS485 Adapter
- Recommended devices, with RS485 on board:
- [T-CAN485](https://lilygo.cc/products/t-can485)
- [KAmodESP32 POW RS485](https://wiki.kamamilabs.com/index.php?title=KAmodESP32_POW_RS485)
- any other ESP32 device with RS485 interface
- [ESPhome](https://github.com/esphome/esphome/releases)
- [HomeAssistant](https://www.home-assistant.io/)
- esphome should installed on your computer or HASS instance (ESPHome Builder)
