V5 Firmware - Problem Solving

Dr Chris Horne CEng FIET
Updated

Unfortunately a number of our customers have run into problems following the update to the V5 firmware.
If this has happened to you, we are very sorry and will do out best to get everything working again as soon as possible.  The problem may be very simple to fix - Here are the most common issues.

 

Are all your devices update to V5?

If you have more than one myenergi device then it's possible that they have not all been updated to the latest firmware.  You can check this on the "Information" menu.  Make sure that all zappis and eddis are on the latest V5 firmware

 

My devices don't talk to each other any more / my devices appear offline in the app

With the update to V5 there may be a problem with the radio channels on each device not matching up.  Please try putting your devices on Radio Channel 1 or 4.
See this article for more guidance: Checking the radio communications channel

 

I'm getting Grid CT Lost / My devices aren't diverting power any more

There are a couple of possible reasons why this happening:

  1. Are all your devices on V5 firmware?
    Hopefully you have already checked this, but you may get the Grid CT Lost message if you have a mixture of V5 and older firmware versions. See V5 Firmware - Updating a hub with a serial number starting with a "1"
  2. You do not have a "master" device in your network
    If you only have one zappi or eddi, it needs to be set to be the "master" device.
    Check on the Advanced - Linked Devices menu
    There should be a tick next to the "Set Master" menu item. If not, select this menu item and press "+" (on zappi) or "tick" (on eddi) to confirm
  3. There must one (and only one) Grid CT set on your system
    As zappi / eddi are designed to measure the power flowing to/from the grid this should be the default set up but it is clear that there are a significant number of people who do not have a Grid CT. This will lead to the Grid CT Lost message,

    Important: We have updated the firmware to suppress the Grid CT Lost message if none of the CT's are set to "Grid". The latest firmware versions can be checked at Current firmware versions / updating your firmware
    If you are not on the latest firmware then please try updating your firmware again to see if this message is cleared.

You will also get this problem if there is more than one Grid CT setup on your system.  If you have more than one zappi or eddi check the CT Config settings to make sure that there is only one Grid CT configured.

 

My EV won't charge - I get "Charge Delayed" on the zappi screen

This seems to affect anyone with a zappi V2 who was on firmware V3.147 or earlier.

For anyone with the problem where zappi is saying "Waiting for EV" the fix is very simple.

Please unplug your EV and then go to the following menu

  • Charge Settings - ECO+ Settings
  • Select the menu item "Stop delay"
  • Change this to 30 seconds

 When you plug your EV in again it should charge as normal

 

I can't update my eddi v2.1 or zappi 2.1

If you have an eddi 2.1 or a zappi 2.1 (with the built in WiFi) the best way to update the firmware is to connect the eddi directly to the internet (WiFi or wired Ethernet)

Instructions on connecting the to the WiFI can be found -> here <-

If you have one of the original hubs (hubs with a serial number starting with a "1") make sure that it is running the latest firmware (at least v5.005).

Although WiFi (or Ethernet) connection is preferable,  it should be possible to update over the radio link.

  • On the device that is to be updated the WiFi module needs to be turned off.    Check this on the menu "Other Settings (or Device Settings) - Internet - WiFi - WiFi Config"
  • Now try the firmware download again
  • If the firmware still does not download and you are using a "vHub"/"Gateway Device" then 
    • Reboot the device being updated by turning it off and then back on again
    • Then, on the "vHub" / "Gateway Device" download the firmware (Internet - Firmware Update menu") and wait for the download to complete
    • Finally, on the device you want to update, try the firmware download and install.

 

Local Comms Lost!

Some customers have reported Local Comms Lost! after the update.

When they look at the Linked Devices Info screen there are ? next to one of more of the devices.

It turned out that these were devices that had been replaced but had not been deleted from the linked devices list.

The problem was resolved by :

  • navigating to the Advanced -> Linked Devices menu
  • selecting the device with the ? next to it
  • then selecting "Remove device"

Important - make sure that correct devices are deleted. Only delete devices if they are no longer part of your myenergi network.

 

 

Installation Limit!

There have also been a couple of reports of the EV not charging (even though all the settings are correct) and then when the customer put their zappi in STOP mode the display reported "Installation Limit!".

This is fixed by changing the priority of the myenergi devices, either

  • In the app, if you have two or more devices (zappi, eddi and libbi), or
  • Using the local controls on the zappi.  The menu is Other Settings - Advanced - Linked Devices - Devices
    • Select the zappi
    • Then change the priority

It may then be necessary to unplug the EV and then plug it again for the charging session to start.

 

 

Eddi - Clock wrong / Update from cloud cannot be set

On the V1 eddi (serial numbers starting with a "1" we have had some reports that the clock is wrong following the update to V5 and the "Update from Cloud" option on the Time and Date menu cannot be set.  While we dig into the reasons for this, the problem can be resolved by factory resetting the eddi and then pairing it with your other devices again.  If you do need to do this then remember to set the CT Settings on the eddi too.

 

Our apologies for anyone who has run into a problem with this upgrade.
If you still have problems having tried the above, then please email support@myenergi.com with details of the problem and the serial number(s) of your myenergi device(s).

Thank you
