@tjog the gateway does not remember anything, regardless if you have a controller or not. Nodes can be programmed to remember their state. The example with rotary encoder at https://www.mysensors.org/build/dimmer does that if you want something to base your sketch on. Note that the first example on that page does not store state; it relies on a controller instead. Not sure what you mean by rules, but if you enter rules in your controller they will most likely depend on the controller being available.

Hahah regarding the alcohol i think thats the problem! I will check everything again with your pointers, thanks for the answer I actually had a second look after i posted and made some changes, i got a lot less errors but still wasnt able to compile. I will have a new pass Thanks
