How to use ':' in MQTT binding

[Dim (Angelos)]

Send a : in a MQTT Command

If you made a file like transform/ED001.map: ON={out12:1} OFF={out12:0} and changed your binding config to: Switch ED001 { mqtt=">[openhab:mytopic/test:command:*:MAP(ED001.map)]" } I believe (haven’t tried it) that the ON command will be mapped to {out12:1} which will be used as the message to publish to mytopic/test.
