Modbus is a polling protocol so there's no way to observe changes from an event. To add something to the integration I need to know the registers and how they describe a device. On top of that, the Modbus/TCP interface is actually a proxy that the inverter abstracts from internally. It's not a one to one mirror of all data available in the inverter. |

The power controller SMRT-HOT-WTR-48-S2 with temperature sensor HOTWTR-SENS-RW-S1 is not that smart.. No actions can be automated based on the sensor output.
Is there any kind of sniffer I can add to the modbus to help identify the powercontroller and temperature sensor coms so that I can automate actions in HomeAssistant instead?
