Installation Resources


  • Q :What if CURB reports a weak signal?

    A :If the configuration screen shows 3 green dots or less, wire the CURB hub to a circuit of different phase.

  • Q :What if there isn’t any connectivity through PLC (Home Plug) device?

    A :If you don’t see flashing PLC lights, it probably does not have a connection. Inspect your connections from the CURB to the breaker, a loose wire can cause a bad connection. Make sure the Home Plug is not connected to a power strip. If the CURB hub cannot connect, but local networking is otherwise online, try disconnecting and re-connecting the CURB hub.  If it doesn’t connect once the local router is online, try wiring the CURB unit to a different circuit. To diagnose your connection strength, view the hubs page within the connection app.

  • Q : What if the router, PLC and CURB hub are not on the same circuit?

    A :This can cause connection errors and we advise against it. A better solution is to put the CURB hub on different circuit, but on same phase. Disconnect power from the CURB hub, reboot the router, wait for connectivity, then plug the CURB hub back in.

  • Q :How can I tell if the network is down? What happens if I install two PLCs, and my network stops responding?

    A :Each home generally only needs one PLC device. If CURB can’t connect to via PLC, it is possible that the network is down. If the home already has PLC installed, we recommend removing the existing PLC and attempting to use the PLC included with CURB. Be sure that pre-existing devices (such as ADT home security) continue to work before proceeding.

Hardware Configuration

  • Q :What if the home router is on a GFI or arc-fault breaker?

    A :If you are wiring the CURB to a GFI or arc-fault breaker, be sure to connect the neutral (white) wire into the breaker, instead of the neutral rail.

  • Q :How can I determine which breaker powers the router?

    A :You may need to determine which circuit powers your router through the process of elimination. This is important in order to ensure strongest PLC signal.

  • Q :What if the installation is incomplete, and I need to regain access to the install application?

    A :Go to and reenter the serial number of the hub. The installation process will save your data from where you left off.

  • Q :What if there’s not enough space in the circuit breaker panel for the CURB hub?

    A :Install close enough to run CT wires through the panel housing.  As long as wiring follows local codes, it is okay to install the CURB hub outside the panel as a last resort. If you install on the outside of your panel, be sure to install in a “suitable” weather-proof enclosure.

  • Q :What if there aren’t any open network ports on the router?

    A :You may need to purchase an Ethernet switch to expand to the desired number of ports.

  • Q :What if the router is inaccessible? What if there is no router?

    A :An accessible router is specified in the product requirements. However, if the customer has WiFi only, you can optionally use an Ethernet to WiFi bridge, and plug the HomePlug receiver into the bridge. In order to save time, this step should be done before the installation.

  • Q :How do I determine which of the main circuits is of the same phase as the router within the sub-panel?

    A :First, use a multi-meter on the sub-panel to determine which incoming phase matches the circuit with the router. Second, label the phases of your circuits with the provided stickers – circuits matching the router phase should be labelled “A” while circuits NOT matching the router phase should be labelled “B”. Third, find the circuit on the main breaker panel that matches the sub-panel main that matches phase of the router. This can be accomplished with a continuity tester, by examining distinguishing characteristics of the wires, or by trial-and-error turning off of the subpanel circuits on the main panel. Once identified, be sure to label the matching circuit “A” along with all other circuits of the same phase.

  • Q :The circuit that has the router is B phase, but you want me to label as A phase. This doesn’t make sense, what should I do?

    A :From time to time, the process we’ve outlined leads to labeling breakers in a manner other than expected. This is for the sake of network reliability. We label the circuit leading to the router as A in all cases. This simplifies the install process when connecting clamps to the CURB hub and maximizes PLC connectivity.

  • Q :I don’t have enough of the right size clamps?

    A :You can use larger clamps on smaller circuits if needed, but this will decrease accuracy. If you need more large clamps, please contact CURB.

  • Q :I only have one CURB, but have multiple circuit breaker panels. What should I do?

    A :Either install an additional CURB hub in each panel, or install one CURB hub in the main panel with CT clamps on each of the sub-panel mains (summarizing subpanel activity).

  • Q :Which clamp is which?

    A :30 is the physically smallest clamp; 50 is medium-sized; and 100 is the largest.

Installation App

  • Q :What if I get an error when I search for the CURB ID?

    A :Double-check the serial number printed on the bottom of the CURB hub. It is case-sensitive. If you continue to get an error, please contact CURB support.

  • Q :What should I do if I get HTML or AJAX error?

    A :The CURB hub may have been configured by another installer. Please contact CURB support for help.

  • Q :I’ve already secured the CURB hub in circuit panel, but I need to get the serial number?

    A :Check the packaging for serial number sticker. Keep in a safe place. We advise you write the serial number or take a picture before installing.

  • Q :I entered the panel schedule numbers into the CURB software instead of the green sticker numbers. What should I do?

    A :This is an important part of the installation process because it enables customers (and technicians) to most accurately reference circuits in software. Review the panel screens in the installation software and correct any circuits with the wrong numbers.

  • Q :What if I don’t see anything in the dropdown list of available circuits?

    A :If the list of available circuits is empty or missing circuits, you may have either (a) forgotten to identify that phase of the missing circuits, (b) specified the wrong phase for the missing circuits, or (c) chosen the wrong panel from which to choose circuits.

  • Q :Amps on mains is reporting as a negative number. What should I do?

    A :If the building is not generating power via solar or other non-grid sources, you can check the “+/-” toggle on the Hubs page for that circuit. If the building is receiving power from solar or another non-grid source, first determine if it is generating more power than being consumed -- which can be the cause of a negative total. If more power is being consumed than generated, it is safe to check the “+/-” toggle for the circuit.

  • Q :What does the “Display Name” mean in the CURB Hub section?

    A :Display Name is the name of the register that shows up in the User Interface of the customer’s dashboard.

  • Q :What does “Multiplier” mean? Is this used for combo throws?

    A :This option is for combo throws. Choosing a multiplier will multiply the measured voltage of the circuit by 2 (for a double-throw) or by 3 (triple-throw). This is useful if you have a balanced-load appliance (such as a furnace or water heater) and you only want to use one CT clamp on one phase (e.g. one half of a double-throw breaker pair).


  • Q :What’s the difference between line-side and breaker-side solar?

    A :In breaker-side solar installations, the output from the solar system is connected to circuits in the main breaker panel. Thus, in breaker-side installations, the power reported on the mains can fluctuate between positive and negative numbers depending on the balance of power between production and consumption.
    In line-side solar installations, the output from the solar system is connected to the grid in parallel with the main breaker panel. In such configurations, there will NOT be any circuits in the main panel connected to the solar system. As a result, the mains in the main panel will only report power consumption. CURB software sums the consumption and production values in order to report net power.

    Be sure to identify the correct solar installation type for each solar circuit in the configuration software.

  • Q :How do I bridge a solar panel that is far from my circuit panel?

    A :If the solar breaker panel is far away from the main circuit breaker panel, use an approved data cable (such as Cat-5) to extend the length on the CT-clamp wires. Be sure to follow applicable building codes for the region in which CURB is being installed.


  • Q :How do I create a new account?

    A :In order to create a CURB account, you must purchase a CURB hub. During the installation process, the installer will enter the hub serial number and customer email address into the installation app to initiate account setup.

  • Q :I lost my password. What should I do?

    A :You can reset your password here.

  • Q :How can I change the email address associated with my account?

    A :At this time, if you would like to change the email associated with your account, contact

  • Q :I don’t see any active data. What should I do?

    A :If you have just set up CURB for the first time and completed the installation process, it may take up to a 10 minutes for data to display in the app user interface. Double-check the PLC for proper connection. If that doesn’t work, inspect the CURB hub within the circuit breaker panel for connectivity status by checking the connection indicators.

  • Q :My bill is not accurate, what should I do?

    A :Make sure that you have entered the correct zip code and chosen the correct energy plan within the “Energy Providers” section of the app. If the totals still don’t match, please contact CURB so we can investigate further.

  • Q :In my list of circuits, what does “other” mean?

    A :“Other” represents the total of all unmeasured circuits in your home. It is calculated by subtracting the sum of all measured circuits from the total consumption on the mains.
