Modbus profile datatype conversion

[jmir]

Hi,

I've seen that when converting to bool value on knx side, each time that the register is read from modbus it's uptdated at knx side (even if it has the same value).
Is there any way to uptade it only on change?

Code:

       {"name": "Input2_Type_[R/W]",
    "bus_datatype": "bool",
    "type": "register",
    "datatype": "uint16",
    "address": 108,
    "read_offset": 0,
    "read_count": 5,
    "writable": true,
    "value_delta": 2,
    "value_multiplier": 1,
    "value_custom": {
        "0": "Current",
        "1": "Voltage"
            }    
    },

I've tried disabling write, and read individualliy (read_count: 1) but it's updated on each polling...
