Ohm Installation Guide | Installation Checklist
Installation Checklist
Please ensure all materials, components, and
accessories are ready prior to an installation.
This checklist will help you plan your install.
Completed Site Survey (Project Scope)
Prior to installation, a Site Survey should be completed
by the Service Provider. The survey will inform you
what hardware goes where at the installation site.
If you do not have a completed Site Survey or have
questions contact [e-mail] please have
Customer and Building names ready when calling.
Service Provider has been informed
of the installation schedule
Service Provider should be informed of the installation
schedule at least 48 hours in advance so they can ensure
an installation support representative will be available.
Ohms, antennas, Mini UPS 5V power
adapters, and mounting plates
If there is no metal surface to mount the Ohm unit, nd a
suitable location with access to a nearby outlet and install
the metal mounting plate. If any CT clips will be attached to
the Ohm, it will also need to be near the electrical panel.
Ohm Links, antennas,
and power adapters
Each Ohm Link should have a 9V AC-AC and 5V DC
adapters for reading voltage. 5V is necessary and 9V
is optional for real power (high accuracy). If the Link
will run on batteries in a single-phase installation,
have (3) AA lithium Ion batteries per Link.
Ohm Senses
You will need: Mounting tape or Velcro tape and
AA batteries. (2 batteries per Ohm Sense unit).
Installation tools
You may need a drill, drill bits, mounting screws, wire
cutters, zip ties, cable straps, screw drivers, spare
breakers, etc., to properly install Buddy Ohm.
Electrical outlet parts
If a new outlet needs to be installed, be sure
to have all the necessary components like a
junction box, outlet, faceplate, and wires.

Installing the Buddy Ohm
Buddy Ohm is the main base unit which other
devices communicate with. Buddy Ohm connects
via cellular network to Buddy Cloud.
Inside the Ohm box is the Ohm device and an antenna.
Open the top cover of the Buddy Ohm device
and Install the antenna to the Ohm.
Power on the Buddy Ohm using the power supply.
Note: Use the 5 volts power supply.
After you plug in your power supply, the cellular dongle
will ash green or blue for less than a minute. After
a minute, the light should change to solid green.
Note: If the light doesn’t become solid blue, that means
there is no cellular connection and the Ohm is unable
to connect to the Internet. See troubleshooting options
below for alternative connections to the internet.

Installing Current
Transformers (CTs)
Note: This step includes working with the electrical panel
rack. If required, contact a qualied electrical expert.
Locate the electrical panel.
Open the panel cover using the necessary tools, if needed.
Use the required amperage CT clips and install to
the desired circuit(s) that you want to measure.
Important: Ensure CTs are installed observing correct
polarity (facing the proper direction). You will receive
a negative reading in your Ohm Portal if CTs have
been installed in the wrong direction. When installing
a current transformer (CT), the arrow printed on
its plastic case has to point to the load you want
to monitor, away from the breaker or source.

CTs have polarity (facing the proper direction).
I am not seeing any data on my energy
Feed Cards in the Ohm Portal:
āāTry resetting the Buddy Ohm.
āāIt is best to plug CTs into the device
before powering it on. .
Sense is reporting, but the Sense’s Feed Card
in the Ohm Portal often turns red:
āāRemove the Sense’s cover and take the antenna
(the black wire) out of the case, on a straight
vertical line. Please make sure the Buddy Ohm
is installed in a vertical position, in the highest
location possible, and free from features that
could interfere with RF communication.
āāIf the problem persists, consider relocating
the Sense closer to the Buddy Ohm
Sense stopped reporting. Portal widget solid red:
āāRemove the plastic cover from the Sense and Make
sure the green LED light next to the terminal block
blinks every 10 seconds If not, replace the batteries
After provisioning a Ohm Link, the associated Feed
Card(s) in the Ohm Portal remain(s) yellow:
āāMake sure all provisioned inputs are rmly plugged
in (both CTs 3.5mm jacks and power adapters cables)
āāMake sure the antenna is rmly installed
āāPower cycle the Ohm Link (remove all power sources,
or press the small push-button installed on the PCB)
All Feed Cards in the Ohm Portal are red:
