@MikeF Dirtypcbs rarely takes more than 3-4 weeks for me too (in germany), but you are right, a local source would be great. There are several producers here too, but for everyone I know prices are at least 5 times what the chinese take.
If you (or someone else) finds a european service that produces prototypes (1-3 boards) for less than 15€ per piece please share it! Could come in very handy when developing new boards.
@towme yes, the majority of MySensors users use the nrf24. It is cheap and many users prefer not having to install wires to all their sensors. But, maybe more importantly, nrf24 was the first communication supported by MySensors so the combined community has much more experience with it.
All example sketches are supposed to work with any transport type (nrf24, rfm69, rs485, ...). The motion sensor example has a list where users can decide which one to use. But I see that the alternative of not enabling any of the transports might not be intuitive, so there the documentation could be improved.
The project is that I have a box with objects in it. Each object has a placeholder within the box. I want to place a sensor in the bottom of each placeholder and have it tell me if an object is within the placholder or not. With RFID i want to know what is missing without opening the box.
