There are a few ways that you can go wireless:
1.) You can wirelessly bridge the hardwired RS-485 network at any point using our 485Bee wireless mesh radios. You need at least two 485Bees (one on your meter(s) and one on your communication device, such as the EKM Push3). Numerous 485Bees can connect multiple strings of meters to one communication device in what is call a mesh network.
More information about mesh networks is available here:
The RS-485 connection is A to A and B to B on the meter and the 485Bee.
For the EKM Push: It is A on the 485Bee to A+ on the EKM Push gateway. Similarly, B on the 485Bee to B- on the EKM Push gateway. The Push3 uses a pluggable terminal block for A+ and B-.
The 485Bee will fit in our Large and XL Watertight Enclosures. Another option is to make a homemade watertight enclosure out of PVC pipe with pipe caps, if you are going to be installing these outdoors.
You can connect 6V-42V DC power to the EKM-485Bees via the terminal blocks — or use a plug-in barrel jack male plug. The male plug end would be the most common: 2.1mm ID x 5.5mm OD type.

2.) The second way to go wireless is for internet connected meters. To make the internet side of the the Push3 gateway wireless, you would need to set it up to connect to your WiFi network.
3.) The third way to go wireless is also with internet connected meters. Instead of connecting to a typical wifi internet router, you could connect the Push3 gateway to a cellular modem. This would allow you to send meter data to the cloud from remote locations where standard internet access is difficult or impossible. The downside of this option is that cellular service providers will charge you for the cellular modem as well as a monthly for the service. This expense varies by provider. We offer one option for this with a 2 year, prepaid, unlimited data plan.
