Just want to clarify this if someone do not understand the purpose of these smart lock handles:
The idea with door/window locks for these type of patio/terrace/balcony/garden doors and windows that have the option to add an interlocking handle on the outside as well if you want/need to be able to also open the door from outdoors (which not everyone wants). So it is only the inside handle that contains any smart components. Therefore most sell/offer matching dumb handles to match the same style.
Note as such that these types of smart door handles are not meant for your main door but instead only for patio/terrace/balcony doors and windows that you normally only unlock and open from the inside.
Also a similar concept is used in the classic “Yale Code Handle” series that has been around for many years in Europe from ASSA ABLOY Group, but those lack wireless remote control, instead they only feature a slimmed-down keypad for unlocking by entering a PIN-code that lock/unlock it via solenoid pins.
After I have been unable to add my sigenia Smart Window to Home Assistant (worked once, not anymore) I just ordered one of those secuyou. To be honest, I am not sure what I clicked on the only partially English site…
