Taką odpowiedź otrzymałem o firmy GreenWave producenta listw:
"In the use case situation of a Electricity shut down, the Powernodes are rebooted just as all other electrical device in the home. Meaning that devices such as the Kitchen own -> the display will be blinking and the end-user will have to reset the date and time on the display. In addition, the Home Gateway will rebooted in which period the Gateway will have lost data and the connection to all Z-wave devices in the home. Actually, the gateway when coming back on-line should be the trigger -> remembering and also pushing the previous schedules/scenes to all Z-wave devices in the home. Thus, bringing them back to the previous settings. So, what I am saying is that it is the gateway and backends job -> to bring the inhome Z-wave devises back to previous schedules after an electricity outage (not the z-wave device)."
Więc wychodzi na to,że wszystkiemu jest winna HC2 która nie posiada zaimplementowanego specjalnego szablonu dla listwy PowerNode...
