Bad news: The memory chips, that allow the green dot compatibility have gone end of life and are not produced anymore. There is a newer replacement chip, unfortunately it doesn't work with the Davis security used in the firmware/console. It was going to happen sooner or later!
I have purchased the last 33 chips, after that I will have to try to use a different package, long term we are pretty much in trouble.
So if you want a logger order asap before the 33 are gone.
I will update this thread with details as I develope the new logger.
Regards.
