I would have thought that if it is a GEN2 model it might have more memory and be able to download 15min interval data (not 1hr). I will be forced to use API to write data to an SQL database on a more regular basis, which is a hassle. It doesn't have an output contact, which doesn't bother me too much, and it has a much faster processor that the 3EM Gen 1 model.
