My LeakSmart Hub 3.0 isn’t activating.
First, make sure the LeakSmart Hub 3.0 is plugged in with the supplied AC power cord; it will not activate using the battery power alone. Recently, we found that many of our customers are not using the supplied AC power cord. Check the cord for a label that reads “LeakSmart Hub 3.0”. If you do not find this label, then you may have mistakenly used the other AC power cord intended for the valve.
