Hi All,
this is defenitely a great thread about things weare able to do with openhab. I build a state machine as a rule in openHAB and it worked like a charm, but then i found the article about NodeRed. Thanks to @rgerrans
Because i heared often about NodeRed as one of THE IoT tools, i decided to give it a try. Installed NodeRed on an fresh openHABian installation (Thanks @ThomDietrich) and startet.
It is really simple to work with NodeRed just open the broswer an goto http://NodeRedServer:1880/ and start. I searched around and found the FSM node that represents a Finite State Machine in one node. Perfect, but as we know we have a little timer issue to overcome this jitter problem with many of the washing machines and therefore i could not use the FSM node.
Ok, i had to build the FSM with timer support on my own. The standard time in NodeRed could be retriggered, but not stopped, so i had to find a silution on this → stoptimer node did the trick for me.
At the end i created a flow that receives the power consumption from an item and sets the surrent sate of the washing machine using a String item.
For all who are interested the flow to import it into node red

Based on this experience, i this NodeRed is in minimum a perfect addon to the rule engine of openHAB and with openHABian it is a piece of cake to set it up.
Any comments, optimisations and and and are welcome.
