Unable to charge if home charger supply has Ethernet over power

[MichaelJHunt]

Enough of computers this isn't the forum for them.

It’s an EV forum. Where EVs have lots and lots of computer issues that need resolving.

But, yes, probably a bit off topic

(Unix & Linux etc both allow the != operator ?)
Don't forget your bat ?

How gracious.

I am having a version of this problem, I think.

I had a wallbox pulsar plus installed on Thursday. They tested it all and everything checked out. The lights on the unit were green/normal and no errors on the app. The last thing they did was switch on all the circuits at my fuse box. One of these is the PowerPoint that had a BT mini hotspot for my Wi-Fi in that part of the house.

Now I get an error reading on the app and an odd light on the unit itself. Wallbox help pages don’t even list that light as an option.

Will switch off the hotspot tomorrow morning and see if that works.

Hmmm presume the wallbox communicates via WiFi?
And the hotspot is a WiFi extender (plugs in to a socket & rebroadcasts a WiFi signal)?

If so suspect some conflict over IP addresses or the wallbox was setup to connect to the router WiFi whose signal is now being "drowned out" by the extender?

Keep us posted

I switched off the whole Wi-Fi extender thing and the wallbox display changed to this.

The wallbox app says a red light means “there is an error”. Nothing of any use to try and solve it. For now, I have switched off the EV charger circuit in the fuse box so we can have functioning Wi-Fi. It was running very badly since the charger was installed so I am thinking there is an IP address conflict or similar. Don’t know how to solve that though.

Installers back & show them the with & without effect?

Have now power cycled everything. Power line Wi-Fi is working ok. Wallbox is connected to the internet and I can access it on the app. Still showing red light. I rang support helpline. They could connect to the box and can see there is a broken sensor. They will send a replacement unit.

Fingers crossed that fixes it.

Alongside this, Western Power Distribution are upgrading my main fuse next week (free) Also getting my earth connection looked at and possibly changed from TT to PME (about £120). The installers said that can make a difference.

Looks like the power line thing was not the cause of the wallbox error but I have read other threads that say the MG doesn’t like power line Wi-Fi so that problem is still to come.

I don't think power line wifi has ever been a problem is power line ethernet

It’s not the car that is the issue - it’s the “intelligent” charge point that is the problem.

I recently replaced my old "BT Broadband Extender" with a much later technology "TP-LINK Powerline Adaptor". This caused havoc when trying to charge my MG ZS EV (you can hear it repeatedly trying to charge). In desperation I replaced the TP-LINK adaptor with a Netgear offering and got the same problem. Conclusion: the root cause is the use of the latest technology standards.
I contacted the supplier of my charger "Myengie" who asked if my car was an MG ZS! Seems this is a known problem. Sadly, my dealership don't or won't understand the issue. So, how do I contact MG??

It is very important to understand that all Ethernet over power devices emit RF interference and cause signal jitter on the wiring too. There are two rules that must be followed before anyone qualified will diagnose this issue. First all adapters must be on the same ring main circuit, no exceptions. Second all devices must be plugged directly into a BS standard outlet directly on the ring main (no extension leads) and no sockets should be spurred off from that ring main. I would also say that interference is compounded by faulty earthing “anywhere” on your domestic circuit. I have seen poor EV charger installations that don’t provide decent earthing.

I put in a hard wired Cat5e network in years ago and haven't looked back.

When are you upgrading to Cat8 ?

I don't envisage that happening
Funnily enough, my HyperVolt isn't actually hardwired because the Wifi connection works perfectly and it's no more than about 6 feet away from the Router!

Perhaps you should move the router further away in case you get microwave reflection bounce.

That could be what's making it all hang together...

Rule of thumb

Any device that is stationary that needs network connectivity, should be hardwired with a cable.

Wifi is for laptops, tablets, and mobile phones.

LAN extenders that rely on the power grid is not to be used for anything, as they are crap

This is my experience from working in IT for many years.

Oh, and if you need multiple hotspots to cover your house with wifi, the same rule, for stationary devices apply.....Mesh systems are the root of all evil.

And ever has been so. Can't beat Cat 5. (IT for many years myself.)

guess this happens because EVs use powerline for comms over the DC power connection to mediate the charging/discharging, see: Bidirectional Charging - openinverter.org wiki
