@conde No problem. Using a common language all users can benefit.

I had similar problems with some of my nodes. To fix it I forced them to use the repeater as the parent node. Once I did that the nodes worked perfectly.

@conde From what I can see both of them are Nano 'clones' with with different serial-usb converters. Some clones get the 3.3v supply (what you use for the radio) from the converter chip. This is a weak (low-amperage) supply possibly causing the radio to malfunction. Also when a separate 3.3v ldo is used it can be very weak. As you notice there are many assumptions here. Possilbe solutions: add an extra capacitor to the radio power supply > 47uF -or- power the radio from a different power supply (ldo).

Well, the gateway does not retain any information about sensors so it is up to the controller to keep sensors info and data. When gateway is restarted all nodes needs to present themselves again but that should not be a problem for the controller, so there should be something wrong with the Vera or plug in

@ted said: @mntlvr I'm excited to see that mysensors is working with attiny. However, when I compile your code for UNO (can't compile for attiny85 on my IDE), I see the code is about 16kb, much larger than the size of the available memory in attiny85. Did you use a different library? Yes a mysensor library written for the Attiny85 chip. And also remember you need to either make a Attiny85 programmer or buy one. I think the 1st choice is the best. There are many articles on the Web that will guide you on how to build your own peogrammer. So do a little research and you will be greatly rewarded. Patience and perseverance will get you what you need and want.
