Conectric Node.js RS-485 EKM Meter Demo

Quick start for getting up and running with Node.js, the Conectric RS-85 sensor / serial hub, and EKM meters.

Version 3 EKM Meter

$ cd omnimeter-v3
$ npm install

• Edit server.js, replacing all instances of 1d2d with the short MAC address of your RS-485 sensor / serial hub.
• Also replace 303030303030303236313435 with your meter's serial number, encoded such that 0 = 30, 1 = 31, 2 = 32 etc.
• (Assuming that the meter is powered on and connected to the Conectric serial hub):

npm start

You should see output similar to:

> node server.js
