Hello how are you?
I’m trying to solve the problem but I still can’t find the solution, I pass my complete configuration:
ITEMS
Switch LUZ3 "Luz 3"<light>{mqtt=">[mosquitto:CASA/LUZ3:command:ON:ON3],>[mosquitto:CASA/LUZ3:command:OFF:OFF3]"}
Switch LUZ4 "Luz 4"<light>{mqtt=">[mosquitto:CASA/LUZ4:command:ON:ON4],>[mosquitto:CASA/LUZ4:command:OFF:OFF4]"}
Number Tempcasa "Temperatura interior [%.0f °C]" <temperature> {mqtt="<[mosquitto:CASA/TEMPERATURA:state:default]"}
Number Humcasa "Humedad relativa [%.0f %%]" <humidity> {mqtt="<[mosquitto:CASA/HUMEDAD:state:default]"}
