HōlHōm+ Meter Connection

Connecting your HōlHōm+ to your meter will allow your HōlHōm+ to receive your electricity usage information from the Meter Data Collector every minute. You are able to view this information on your HōlHōm+ teaching smart thermostat screen, using the Myenergate web portal or using your MyEnergate mobile application.

The Meter Data Collector works with HōlHōm+’s built-in Meter Data Receiver.  The collector attaches to the meter provided by your electricity provider where it gathers information about your energy consumption and transmits it to HōlHōm+.

The Meter Data Collector communicates with HōlHōm+ only.

If you have a ZigBee-enabled smart meter you can use HōlHōm to connect to your meter.  See HōlHōm Meter Connection instruction.

Verify Your Meter’s Watt-Hour Multiplier (Kh, Ks or Kt)

The Meter Data Collector works only with digital (electronic) meters with a disk emulator that uses a watt-hour multiplier between 0.1 and 3000.0. The watt-hour multiplier is sometimes called a disk or pulse constant.

The watt-hour multiplier is indicated on the face of the meter, usually with the letters Kh (less often the letters Ks or Kt). In most cases, the watt-hour multiplier is 7.2 if it has dials and a spinning mechanical disk, or 1.0 if it has a digital readout.

 


Determine Your Meter Type

In some cases, it may be necessary to adjust your sensor unit to fit your particular meter. Therefore, it is extremely important to determine exactly what kind of meter is installed on your premises.

Locate your meter and use the following illustrations to determine its type.

Type 1 - Electromechanical


 

Type1Meter

This type of meter has dials and a spinning disk.

The sensor reads the revolutions of the disk and transmits the information to HōlHōm+/Foundation.


Type 2 - Optical Port On The Face, 1.5 Inches Or More From The Outer Rim

 

Type2Meter

On this type of meter, the optical port is located at least 1.5 inches (37 mm) from the meter’s outer rim.

If in doubt, measure the distance using a ruler.

Note: The optical port can be located at either the right (3 o’clock) or left (9 o’clock) position on your meter.


 
Type 3 - Optical Port On The Face, Less Than 1.5 Inches From The Outer Rim

 

Type3Meter

On these meters, the optical port is on the face, located less than 1.5 inches (37 mm) from the meter’s outer rim.

If in doubt, measure the distance using a ruler. (One is printed at the end of this guide.)

This type of meter may require you to mount the supplied rubber shims on the underside of the sensor.

For example, Elster RS1/REX meters require one shim. Elster RS2 and Sensus iCon A Residential meters do not require a shim.


 
Type 4 - Optical Port On The Top

 

Type4Meter

On this type of meter, the optical port is located on the top portion of the meter.

This kind of meter requires you to reconfigure the sensor and install the clear alignment template.

Install Your Sensor Unit

Please read Important Safety Precautions before starting the installation.

Important: Turn on a high energy-consuming appliance in your house, such as your electric stove or dryer. This temporarily increases your electricity consumption and enables the sensor to begin reading your meter’s output in less time.

  1. Go to your meter, taking the following items with you:
  • This guide
  • Sensor unit
  • A clean damp cloth
  • 1 large flat-head screwdriver
  • Clear alignment template (if you have a Type 4 meter)
  • Stepping stool or ladder, if your utility meter is located higher than eye level. DO NOT USE A CHAIR OR OTHER UNSTABLE PLATFORM.
  1. Determine your meter’s Watt-Hour multiplier (Kh) (see Verify Your Meter’s Watt-Hour Multiplier (Kh, Ks or Kt)).
  1. Determine your meter type and perform the appropriate installation steps:

Note: During installation, it is the dark red Optical Sensor (D) that you align with the appropriate optical port on the meter. This is the sensor that is closest to the tip of the sensor head.

Type 1 - Electromechanical
  1. After carefully wiping the meter dome clean with the damp cloth, fit the sensor unit over your utility meter as shown, so that the Sensor Head (C) sits as close as possible to the front of the glass dome.
  2. With your screwdriver, tighten the Clamp (A) until the sensor unit is snug, but can move just enough to allow for slight adjustments. Note: A clamp that is too tight can interfere with proper alignment of the Sensor Head (C) and create communication problems.
  3. Position the Sensor Head (C): Position the Sensor Arm (B) so that it is in line with the spinning disk (use the line on the Sensor Arm as a reference) and the Sensor Head (C) is on or near the center of the meter.
  4. Press and release the RESET button. The red STATUS indicator turns on solid and then starts to flash regularly.
    • Regular flashing indicates that the sensor has detected the signal from your meter. If necessary, adjust the sensor until the indicator is flashes regularly.
  5. If you positioned the Sensor Head (C) correctly, the STATUS indicator starts flashing as indicated below.
    • If it does not, correct the positioning slightly.
