@jkandasa I can confirm that the fix (installing 1.6.0) worked for me here - hopefully for @pillarama too!
@pillarama - Do you also face an issue where you cannot add a new graph or sensor to a dashboard? That was also an issue for me and now both are solved with new version.
Thank you!!!
@avamander Thanks my friend! 
OK Mr. MyController prog, How about SOURCE and ATTRIBUTE ?
@daniele Yes, Message would be good!
The 'source' sends a 'message' to the controller, no problem there.... But then the controller sends a 'message' to the, er, 'destination'.....
But we can't have both can we?
Now I think about it the controller becomes the 'source' of the data in the same way as a node would be considered a 'source'. it's all about where we are looking at the data 'message' from (Einstein had something to say about relative points of viewing the same thing, didn't he?).
@jkandasa How about 'content' or 'contents' for field?
@jkandasa I think that instead of 'sensor' you could use 'source' as all data has to come from somewhere!
Variable vould become 'value' or 'info' or 'data'.
Just my thoughts on an early Sunday morning!
@daniele Thanks for the suggestions. I know I can get the end result I want with operations so probably go that route for now and see what new surprises version 2 brings!
@daniele I experimented with 2x gateway with nrf24l01+ but that seemed to be problematic (not power supply related either).
So now I think I will have one pi for the security sensors only and another for all the rest.
But then I hit a problem as the pir sensors that will usually turn on lights (via pi1 controller) will also double as a motion sensor when the alarm system is active. So I have to get that message from pi1 to pi2.
If I have 2 different pi machines each running it's own instance of mycontroller, what options are there to forward payload between them?
Both will be connected to ethernet so that is an option, but how to do it? Is there a better solution?
@jkandasa Thank you sooooo much for that!
It was the crucial bit of info/understanding that I was missing.
It works fine now! 
If this turns out to be the same in myc2.0, I'll write a tutorial for it.
@jkandasa I did follow that post as much as I could, but where do you get the all important 'channel username' from?
I think that's the bit I don't yet understand!
