Hello,
I got a XBee gateway (X2E-Z3C-W1-A),
can I install the SEP1 or SEP2 in the gateway? and how?
Best regards!
It will not be possible for you to do this.
Recommend you obtain a Smart Energy Gateway model instead:

If this is a new gateway, you might want to check where it was purchased to see if it can be exchanged.
