Bus signal adaptor for translating digital wired bus signals low and high from a wired bus into a wireless signal, - the bus signal adaptor comprising two terminals for connecting two bus wires and means for receiving/ transmitting wireless signals, further comprising a control unit , for translating different logical states of the digital wired bus signal into different wireless transmitting frequencies of a wireless signal and/or vice versa, wherein - the digital wired bus signals are DALI signals, and - the bus signal adaptor is configured to translate the different logical states of the digital wired bus signal in a cyclic sequence of more than two different subsequent wireless transmitting frequencies of the wireless signal, wherein - the cyclic sequence comprises at least: - a first wireless transmitting frequency (F0) for causing a DALI bus to be pulled low; - a second wireless transmitting frequency (F1) for overriding the first wireless transmitting frequency (F0) and for causing the DALI bus to go high; - a third wireless transmitting frequency (F2) for overriding the second wireless transmitting frequency (F1) and for causing the DALI bus to be pulled low; - a fourth wireless transmitting frequency (F3) for overriding the third wireless transmitting frequency (F2) and for causing the DALI bus to go high; wherein said first wireless transmitting frequency (F0) is for overriding said fourth wireless transmitting frequency (F3) to return the output of the DALI bus to low. - the bus signal adaptor comprising two terminals for connecting two bus wires and means for receiving/ transmitting wireless signals, further comprising a control unit , for translating different logical states of the digital wired bus signal into different wireless transmitting frequencies of a wireless signal and/or vice versa, wherein - the digital wired bus signals are DALI signals, and - the bus signal adaptor is configured to translate the different logical states of the digital wired bus signal in a cyclic sequence of more than two different subsequent wireless transmitting frequencies of the wireless signal, wherein - the cyclic sequence comprises at least: - a first wireless transmitting frequency (F0) for causing a DALI bus to be pulled low; - a second wireless transmitting frequency (F1) for overriding the first wireless transmitting frequency (F0) and for causing the DALI bus to go high; - a third wireless transmitting frequency (F2) for overriding the second wireless transmitting frequency (F1) and for causing the DALI bus to be pulled low; - a fourth wireless transmitting frequency (F3) for overriding the third wireless transmitting frequency (F2) and for causing the DALI bus to go high; - a first wireless transmitting frequency (F0) for causing a DALI bus to be pulled low; - a second wireless transmitting frequency (F1) for overriding the first wireless transmitting frequency (F0) and for causing the DALI bus to go high; - a third wireless transmitting frequency (F2) for overriding the second wireless transmitting frequency (F1) and for causing the DALI bus to be pulled low; - a fourth wireless transmitting frequency (F3) for overriding the third wireless transmitting frequency (F2) and for causing the DALI bus to go high; <EOS>
