I try to change the setpoint of my thermostats.
i have to send following message
{
"current_heating_setpoint" : 16
}
my mqtt things and channels
Bridge mqtt:broker:mosquitto "Mosquitto" [ host="192.168.178.63", secure=false, clientID="openHAB2Docker" ]
{
Thing topic WoziThermosLeft "Thermostat Wohnzimmer Links" @ "Wohnzimmer"
{
Channels:
Type number : WoZiLeSetpoint [stateTopic="zigbee2mqtt/WoZiLinks", comandTopic="zigbee2mqtt/WoZiLinks/set", transformationPattern="JSONPATH:$.current_heating_setpoint", formatBeforePublish="JS:setTempThermostat.js"]//
}
}
the js code
(function(x) {
var result;
result = "{ \"current_heating_setpoint\": " + input + " }";
return result;
})(input)
the Linked Item
Number ThermosLi_Setpoint "Solltemperatur am Thermostat links [%.0f °C]" <temp> {channel="mqtt:topic:mosquitto:WoziThermosLeft:WoZiLeSetpoint"}
If i try to change the Setpoint following log message Appears.
2019-11-03 10:36:00.068 [ome.event.ItemCommandEvent] - Item 'ThermosLi_Setpoint' received command 24
2019-11-03 10:36:00.069 [nt.ItemStatePredictedEvent] - ThermosLi_Setpoint predicted to become 24
2019-11-03 10:36:00.070 [vent.ItemStateChangedEvent] - ThermosLi_Setpoint changed from 18 to 24
2019-11-03 10:36:00.071 [vent.ItemStateChangedEvent] - ThermosLi_Setpoint changed from 24 to 18
2019-11-03 10:37:56.746 [vent.ItemStateChangedEvent] - IsttemperaturRaum changed from 22.5 °C to 23.
I found similar problems here but no one seems to fit to my problem 
sorry if i missed something
:edit in my zigbee2mqtt the send message doesn’t appears so it seems the message never goes out if send the message via MQTT.fx
