1. What is the difference between a harvi and a hub

HARVI is used when it’s not possible to hardwire any of the CTs back to the zappi/eddi. Harvi sends these CT readings wirelessly back to zappi/eddi

HUB connects your myenergi devices to the internet so you can use our app to control your devices and to carry out all future firmware upgrades

 

2. Do I need a harvi?

Only if you can’t hardwire any or all of your CTs back to zappi/eddi. Harvi will do it wirelessly (subject to distance and certain obstructions)

 

3. What does a red zappi, eddi or harvi light on the hub indicate?

This indicates a loss of communication between the hub and whatever device is displaying the red LED.

 

4. What distance can the wireless comms on the harvi or hub reach?

We usually recommend no more than around 20-25m although in a lot of cases this can be much further. Each site needs to be assessed on an individual basis for anything that could obstruct or disturb radio communications.

 

5. Can the harvi be mounted outside?

The harvi isn’t waterproof although it can be mounted within a suitably IP rated box that will  prevent water ingress.

 

6. What does a red server LED on the hub indicate?

A red server light means that the hub is not receiving any data from the server.  Check that the hub has an Ethernet cable to your router and that this cable is working OK by plugging in another device such as a computer.    

You should also try rebooting your router and the hub:

  • turn off the hub
  • reboot your router and wait for it to come fully back online and connect to the internet
  • turn your hub back on again

This will make sure that the hub has a new IP address and any routing information (“NAT”) in your Ethernet router are reset.

 

7. Can I use my hub with power line carrier plugs?

Yes.
The hub needs have a hardwired Ethernet connection but this can be:

  • plugged straight into your Router
  • plugged into an Etherner socket or Ethernet switch if you have one
  • or plugged into a “power line carrier” plug – which uses the electricity wiring in your property to extend your Ethernet network
