hi, I have just connected to my ventilation system via Modbus and it exposes a series of Input registers (which i have mapped to sensors) and a number of holding registers that I am still wondering how to map. Ideally they would be both readable and writable, I have seen on the forum many posts about having:
- a sensor reading from the modbus device
- a input helper syncing its state to the sensor
- an automation to write the helper value on the modbus device every time the helper changes
it seems a bit convoluted, is there an easier way?
my main concern is that many of these entities would need this kind of lookup, and I would end up with many additional helpers…
Thanks
