This section is related to troubleshooting problems related to the KNX implementation in Shelly. For general KNX troubleshooting, please refer to a professional KNX installer and the respective KNX resources.Multiple devices using the same Individual address
Such case may arise only if devices are configured (programmed) using different software not connected one to another (e.g. Shelly embedded web interface and ETS software). In case of multiple devices are using the same Individual address this does not violate the operation of the KNX network, but it prevents proper fault diagnostics when such a case occur.Improper Group address assignment
Encoding of KNX Group addresses, i.e. their DPT type, is automatically assigned according to the first object added to that address. Then a case may arise where the DPT type of an object and the DPT type of the Group address to which is assigned do not mach. For example a Group address with DPT 1.001 (switch) may be assigned to a Long push object used for 4-bit dimming control, i.e. DPT 3.007 (dimming) may be done by a mistake. Shelly’s embedded web interface can not check such cases allowing the user to assign any Group address. When such is the case this will lead to inability to operate the improperly configured device, but will not affect the rest of the KNX installation.TOGGLE function not working
TOGGLE function is solely dependent on controlled channel feedback status. In case this function is not working properly is due to missing or incorrectly assigned Group address for the related to that function Feedback object. Check if TOGGLE’s function Feedback object and the controlled channel Feedback object share the same Group address. Controlled channel Feedback object must have its Sending status active otherwise the TOGGLE function won’t work.
