NibeMqttGateway

This project use ESP-01 with Arduino framework to communicate with Nibe 1145 heatpump. ESP-01 interface the heatpump using RS485 interface intended for modbus converter. Data from heatpump is decoded and published using MQTT protocol.

• Support reading of cyclic data
• Support read of specific address
• Support writing specific address

The project uses Visual Code with Platform IO and Arduino platform.

Known limitations/bugs:

• 32 bit values are not coded/decoded correctly
• Published messages that are subscribed will be written back to heatpump.

Use at own risk
