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 Push). 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... Continuing left from right, B comes next, then A on the far right end. (Same for the Push.)
For the EKM Push: It is A on the 485Bee to A+ on the EKM Push gateway. B on the 485Bee to B- on the EKM Push gateway.
A good watertight enclosure option may be to put it in a PVC pipe with pipe caps, if you are going to be installing these outdoors. (We do not supply this.)
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 EKM Push gateway wireless, you would need to connect it to a Wifi Bridge. This will make the gateway wifi enabled. These are available from numerous retailers.
3.) The third way to go wireless is also with internet connected meters. Instead of using a Wifi bridge connected to a typical wifi internet router, you could connect the EKM Push 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.
