Zappi charge points

Only the Zappi or Eddi can be a Master

Is one of your group items on the Harvi ? If so, I wonder if that could be the issue?

Looking at buying a zappi but confused on what type to get? A 7kw would do me at the moment but would like to future proof with a 22kw. Done some reading and have got lost with all the information. Can any house get the 22kw or might be require an upgrade of my electrics? Was reading about upgrading from single to three phase and I don't want that extra cost.

To get 22kW you'll need 3 phase which your house almost certainly doesn't have. If you want to be sure look in your meter cabinet. If there's a single live (brown), neutral (blue) and earth (green/yellow) then you're on single phase

If you have 3 lives (brown, grey and black) then you have 3 phase. Upgrading to 3 phase is a significant investment, would add several thousand to the cost

Most EV owners get on fine with 7kW chargers, once you're charging overnight then it doesn't really matter how quickly you charge

In 11 hours at 7kW I can fully charge my car and have over 400km range. Unless you're driving 500km or more every day then you'll have enough time to recharge the battery

Hi folks, has anyone ever seen a Zappi 2 unit set up without the requirement to connect a to the consumer unit inside the house (fuse-board)
Is it possible to connect these to the main supply box outside the house? (ESB box containing meter). Thanks all

Hi, apologies if this has been asked and answered but couldn't find anything on search. I've a Zappi installation by NMD scheduled for January and I was wondering, can the Myenergi hub be connected to the house WiFi with a powerline rather than being hardwired via ethernet into our router?

Thanks Slave1, looks like I need to rethink where I was going to put the hub so.

Our router is in the attic with WiFi extenders at either end of the house. Has anyone put the Hub in their attic and if so what's the signal strength like? The Zappi would be located approx 22m away from the hub with 3 block walls between them. Is there a need to constantly interact with the hub once its set up or could I install it in the attic and forget about it?

Powerline may work, they tend to be reliable. There is not much on the hub in terms of display to look at. In order to do updates you need to press buttons on hub, but in general I would not update unless you intend fixing a specific issue. You car will still charge with no communication. Assuming you have no Eddi and no solar integration etc, you have no need to use the hub and the app on a day to day basis. Many people survive with never getting a hub.

Just out of interest, what kind of functionality does the car charger alone for any sort of monitoring of consumption etc?

If anyone fancies doing it DIY, current regs say you must install an AC disconnect beside it

You can see consumption on the zappi screen. In my case my commute was fixed, so I could see the car consumed an average of 20kWh per night, for my 110km commute. After I knew that I did not really care to check, but the daily total is shown on screen without pressing anything. Other stats are shown if you press buttons but I am not sure on details. Probably daily, weekly, total. If you have current monitoring on incoming mains for load share via wired current clamp you can see house load, I am unsure on logs for this.

I have a hub and in reality it's not been plugged in for a year, there was no need. I use the timer in the car to set night rate charging.

Hi

I Recently installed a zappi untethered but I'm having an issue with it... the screen is lit up but there is no display??? And it won't release the charger plug... any ideas has anybody come accross this issue???

I use my cars timer for night rate

Did anyone get the HARVI box for their Zappi? What’s it’s use. ?

I set up the timed Eco plus boost function on the original Zappi, works fine, doesn't start until 11pm and gets a full charge by 9am or whatever the cutoff is. My logic was the night rate is specific to the house so it should be the thing attached to the house managing it rather than the car.

Apparently if you have the app you can set up a true night rate charge but there's no difference in what happens.
