}
in my things file I have the following line
Type number : temperatura_target [ stateTopic="shellies/shellytrv-60A423D7EB2A/settings", transformationPattern="JSONPATH:$.thermostats.target_t.value", commandTopic="shellies/shellytrv-60A423D7EB2A/thermostat/0/command/target_t"]
in the items file i have the following line
Number Termovalvola_studio_target_t "Target T [%.1f °C]" (gall) {channel="mqtt:topic:mosquitto:shellytrv-60A423D7EB2A:temperatura_target"}
what is wrong?
I’m able to read all other values, for example mqtt server or wifi_sta ssid…
thanks in advance for your help.
