Beyond the initial cost for the EKM Push gateway, reading meters at a once/minute rate, the data is free.
The EKM Widget and www.encompass.io are also free with no recurring fees. We realize this is not standard in our industry but we feel that by providing easy and free access to your data it sets us apart and makes our system that much more attractive.
The EKM Dash is free to download. It will function fully for 30 days, at which point it will continue to function in a limited capacity. It costs $30 to register the Dash, which is a one time cost. All future updates to Dash are free once it has been registered. The Registration Key can be used on multiple computers running multiple instances of EKM Dash.
