Hello to all,
I am new to esphome integrations and looking for a way to connect my air recuperation device to Home Assistant over local internet network, but using RS485 connection.
Device: SaveAir VTR 150. It uses Modbus (RS485) for communication.
- Use “MAX485 to TTL” for connecting recuperator to ESP32
- ESP32 connects to local wifi network
- Home assistant uses Modbus integration and connects to ESP32 to retrieve and send data to recuperator.
It it possible or I’m missing something ?
