I have the problem, that the MQTT Binding does not send the commands to the Mosquitto Server.
In the log files everything looks fine.
Here is a little test:
I tried to publish something to the MQTT Bus, but when I subscribed to that channel I received nothing.
Item config:
Switch Test_Switch "Test" {mqtt=">[mosquitto:ESP8266/connection_status:command:ON:on],>[mosquitto:ESP8266/connection_status:command:OFF:off]"}
mqtt.cfg:
#
# Define your MQTT broker connections here for use in the MQTT Binding or MQTT
# Persistence bundles. Replace <broker> with an ID you choose.
#
# URL to the MQTT broker, e.g. tcp://localhost:1883 or ssl://localhost:8883
mosquitto.url=tcp://localhost:1883
# Optional. Client id (max 23 chars) to use when connecting to the broker.
# If not provided a random default is generated.
mosquitto.clientId=openhab
# Optional. True or false. If set to true, allows the use of clientId values
# up to 65535 characters long. Defaults to false.
# NOTE: clientId values longer than 23 characters may not be supported by all
# MQTT servers. Check the server documentation.
#<broker>.allowLongerClientIds=false
# Optional. User id to authenticate with the broker.
mosquitto.user=openhab
# Optional. Password to authenticate with the broker.
mosquitto.pwd=xxxxxxxxxxx
# Optional. Set the quality of service level for sending messages to this broker.
# Possible values are 0 (Deliver at most once),1 (Deliver at least once) or 2
# (Deliver exactly once). Defaults to 0.
#<broker>.qos=<qos>
# Optional. True or false. Defines if the broker should retain the messages sent to
# it. Defaults to false.
#<broker>.retain=<retain>
# Optional. True or false. Defines if messages are published asynchronously or
# synchronously. Defaults to true.
#<broker>.async=<async>
# Optional. Defines the last will and testament that is sent when this client goes offline
# Format: topic:message:qos:retained <br/>
#<broker>.lwt=<last will definition>

I’m using the stable version of OpenHAB 2.2
What can I do?
