My Popp 004001 is working fine with the following items:
Contact POPP_Smoke_1_C "Sensoralarm Smoke [%s]" <fire> (gTest) { zwave="9:command=SENSOR_BINARY,respond_to_basic=true" }
Switch POPP_Smoke_1_Sw "Schalter POPP Sirene" (gTest) { zwave="9:command=switch_binary" }
Number POPP_Smoke_1_Battery "POPP Smoke: [%d %%]" <battery> (gBattery) { zwave="9:command=battery" }
All config parameters are on default. Association groups are all set to the controller.
