At this point the best way to control relays is by using the Omnimeter Pulse v.4 connected to your computer running the EKM Dash software: EKM Dash

The EKM Dash will allow you to turn either of the 2 relay controls (50mA 12VDC) ON or OFF, it will also let you turn them ON or OFF from 1 to 9999 seconds. You can do this when reading your meter(s) via the EKM Blink USB converter or over the internet via the EKM iSerial.

You can also set up trigger based control in Dash so that specific data parameters will trigger a relay to turn on or off. More info is available here regarding trigger based control in Dash: https://help.ekmmetering.com/support/solutions/articles/6000128578-how-to-set-up-a-triggered-event-v1-8-3-and-up-

The real-time status (open or closed) of each relay control is provided in each v.4 Omnimeter read in EKM Dash.

We have the EKM Switch120 to control 120 volt loads: EKM-Switch120

The EKM-Omnimeter Pulse v.4 could be used to control EKM-Switch120 or and other load, valve, etc (through external relays).
