Seeing:
2017-02-25 16:28:10.896 [ERROR] [binding.serial.internal.SerialDevice] - No transformation service available!
I have REGEX transform installed according to paper.
Should I open this up as a bug with the 1x compatibility layer???
“Septic_Level_Sensor”
How does that work? 
My septic tank is below my leach field so there is a 2nd chamber that fills
with uh… liquids and once it reaches the level of the float of the pump,
pumps the tank down until the float is off. I have a sensor in the tank so
that I know if the pump dies and the level is too high.
Anyone have any ideas on this?
Probably yes. And it would be even better, if you could also have a fix for it at the same time 
Where should I open the bug? As far as fixing it, I would love to, but I am not a programmer, however I am happy to pay someone who may be interested to do it! 
This would have to go to Issues · openhab/openhab-core · GitHub.
I have just activated BountySource on the repo, so maybe this could help
