I highly recommend itead products, especially for those just getting into MySensors. They remove alot of the pitfalls that electronic noobs (such as myself) encounter when building their first sensor nodes. I used the RMini to build my first relay and it could not have been easier. Many of the troubleshooting problems posted on the forum have to do with setting up relays and these boards eliminate many of those issues.
I also recommend the nano shield from itead to any entry level electronics noobs for setting up early sensor nodes who are not ready for intricate soldering. It provides a nRf socket and a power jack and breaks out all of the nano pins with individual power and ground headers. Just plug in a nano and nRf and program from USB and power the entire setup through a single jack - perfect for beginners.
Sorry for the delay first of all, unfortunately I didn't get the notification of this thread If you are using a latching relay I'd recommend using SensorLatchingRelay1Pin or SensorLatchingRelay2Pins which should take better all the aspects of a latching relay. Then you can still use the safeguard for closing the door after a given timeframe. And yes you have to set a reporting interval even if not intuitive at all. This is because the safeguard is checked in the loop cycle which is called only if a reporting interval is set. So if you have a safeguard set to 1 minute, the report interval should be 1 minute or less. Thanks!
