Hi,
I m using Openhab for a couple of years, and recently i migrated to ver. 2.5.1 (from 2.4)
The only thing I cound not migrate was MQTT binding (from 1.x to 2.5.1). (My configuration is working on MQTT 1.x). I searched the forum for similar questions but I couldnt find an answer for this specific problem.
Problem: a simple SWITCH item publishes (on the correct topic) 1/0, instead of ON/OFF.
[Rich Koshak] at some topic suggested to fix this by changing “Custom On/Open Value”/“Custom Off/Closed Value” in PaperUI.
But i would prefer to fix this through text files.
.things definition:
Bridge mqtt:broker:openhab [ host="localhost", secure=false ] {
Thing topic WaterHeater {
Channels:
Type switch : HeaterTurnOn "Turn On Water Heater" [ commandTopic="relay/command", on="ON", off="OFF", formatBeforePublish="%s" ]
}
}
and .items
Switch HeaterTurnOn "Turn On Water Heater" { expire="1s,command=OFF", channel="mqtt:topic:openhab:WaterHeater:HeaterTurnOn" }
Here is the karaf output
15:42:15.314 [INFO ] [smarthome.event.ItemCommandEvent ] - Item 'HeaterTurnOn' received command ON
15:42:15.326 [INFO ] [arthome.event.ItemStatePredictedEvent] - HeaterTurnOn predicted to become ON
15:42:15.334 [INFO ] [smarthome.event.ItemStateChangedEvent] - HeaterTurnOn changed from OFF to ON
15:42:15.339 [DEBUG] [mqtt.generic.AbstractMQTTThingHandler] - Successfully published value ON to topic relay/command
15:42:17.070 [INFO ] [smarthome.event.ItemCommandEvent ] - Item 'HeaterTurnOn' received command OFF
15:42:17.088 [INFO ] [arthome.event.ItemStatePredictedEvent] - HeaterTurnOn predicted to become OFF
15:42:17.093 [INFO ] [smarthome.event.ItemStateChangedEvent] - HeaterTurnOn changed from ON to OFF
15:42:17.097 [DEBUG] [mqtt.generic.AbstractMQTTThingHandler] - Successfully published value OFF to topic relay/command
and here is the mqtt broker (mosquitto) log
mosquitto_sub -v -t '#'
output:
relay/command 1
relay/command 0
Goal:
How can I post ON/OFF instead of 1/0
Thanks in advance for your time.
Regards
Nick
PS
Also tried the following:
Type switch : HeaterTurnOn "Turn On Water Heater" [ commandTopic="relay/command", on="ON", off="OFF", transformationPatternOut="MAP:onoff.map" ]
where onoff.map contains:
0=OFF
1=ON
