    Yes. The OHME will work as a dumb meter . It’d effectively just be the same as it losing signal.

    Thanks for this. We are in exactly this position. Our Autel showed a recoverable error light this week and we could no longer charge. Have rebooted and even factory reset (which itself was a struggle) to no avail. Like you say Autel said they couldn't help as I was an end user. My question to them was who guarantees the product, isn't it them? We've only had it a month! Does anyone happen to know if/how it can be reset to be a dumb charger? Isn't this why I made sure it was OCPP compliant?

    And how dumb is this situation? Some third party can control our access to our own equipment!? So they can take our money, give us the product, wash their hands of us and also make the product unusable? And the brand doesn't even have to step in?

    Had mine(wallbox) installed last week by Ecoplex. Overall happy with the company and entire proess. Too early to say if I like the unit or not but it does the job quite efficiently. When I first plugged it I was only getting 2.1kw, installer picked up my phone and just wound the amps up and boom car was sipping away at 7.4kw.

    I did manage to get the lights to turn off when in use/not in use as otherwise they were on all the time.

    A note on Ecoplex, as of last week(w.c 16th October) they will no longer install any unit to the Meter box.(I was told by the installer(s))

    Folks, what’s the deal with not installing at the meter box? It would be the ideal location for my future install. Is it a ‘regs’ thing?

    It’s an absolute last resort option, after all other alternatives have been explored.

    It’s more expensive. Handiness is not a valid reason for installing beside the MC.



  • Registered Users, Registered Users 2 Posts: 10,267 ✭✭✭✭dodzy


    I was just thinking with the box at the side of a semi D, you could a) avoid an eyesore on the front of the house and b) avoid having a cable draped across the door/driveway causing a potential trip hazard.



  • Moderators, Society & Culture Moderators Posts: 42,202 Mod ✭✭✭✭Gumbo


    You can still have the charger at the side, out of view. The cable feeding that charger could be fished depending on construction alright.

    But if the CU is on the opposite side of the house then you might have a case and the RECI will decide if that’s good enough for them to go the MC route.

    Im not a RECi so you won’t get a 100% answer here as the few RECi’s that do post have stated they won’t do it.

    Call around a few is the only way. There may be an easy way to get the cable across without it being visible across the front elevation of the property.



  • Registered Users, Registered Users 2 Posts: 10,267 ✭✭✭✭dodzy



    Yeah, cheers Gumbo. I had planned to ring around. Unfortunately the CU is on the other side of the property. I fail to see how even the neatest work would not be an eyesore.

    One other consideration, do you have an isolator in the meter cabinet. If you don't you will need a rec to test the installation and provide a cert for the esb. Esb then come out and fit the isolator and the rec can then go from there. Rarely is it the better way to go.

    When I was doing some research for my own EV install, I came across a channel on YouTube called SOTA electrics, who are EV specialist installers in the UK for mainly Zappy. You'll get a good idea of the way they approach difficult installs from the CU to the charger location. It might help in deciding what way you want it done for yourself when getting quotes.

    Can anyone tell me whether the SEAI grant will involve communicating with my energy provider?

    I received a great sweetheart introductory rate from Bord Gais a few years ago and it was supposed only to last 6 months, but it is still going. It is significantly below current rates.

    I'm looking to get a car charger installed, and for the grant, they are asking for my MPRN - what do they do with this? Do they talk to ESBN? Do they talk to your energy provider?

    I really don't want to rock the boat and bring myself to their attention as I worry this might trigger them finally switching me to the standard rate, this would end up costing me more than the amount I would receive from the grant.

    Any able to shed a bit more light on this area?

    Thanks in advance



  • Registered Users, Registered Users 2 Posts: 24,262 ✭✭✭✭ted1


    They need to make sure that you haven’t used the grant before. It’s tied to the MPRN


    they will not contact your provider



  • Registered Users, Registered Users 2 Posts: 592 ✭✭✭CrookedJack


    Good to know - do they contact ESBN and they might notify my provider?



  • Posts: 2,704 [Deleted User]


    No, your mprn is just used to check if a grant for a charger has been issued previously and added to the Seai database so it can't be claimed again.



  • Registered Users, Registered Users 2 Posts: 3,927 ✭✭✭Beta Ray Bill


    It's incredible how expensive they are. (even if you buy from from like Amazon)

    I've an outdoor socket, I'll be sticking with that.

    I'd be slightly concerned that someone might steal one of these items.



  • Posts: 0 [Deleted User]


    You won't get 7.2kW from an outdoor socket, but if you are happy with that, go ahead.



  • Registered Users, Registered Users 2 Posts: 3,927 ✭✭✭Beta Ray Bill


    I charge a 40Kw Leaf once a week. Cover less than 200km a week so kinda pointless.

    If you had something with a big battery pack and were doing lots of miles then yeah, you'd need 7.2Kw



  • Registered Users, Registered Users 2 Posts: 10,032 ✭✭✭✭CoBo55


    It's still painfully slow. I charged my old phev on the granny charger until I got the CP installed it was torture and it was only a 13Kw battery, it took the guts of 6 bloody hours to fill that tiny battery, most of the time I charged it in the nearby Lidl which knocked around one and a half hours off the charge time. I wouldn't like to be charging a proper EV on one anyway.



  • Registered Users, Registered Users 2 Posts: 3,927 ✭✭✭Beta Ray Bill


    That's strange

    Although I've noticed this too. If I charge the EV in the GF's house it takes longer than it does to charge in my house. my house was recently rewired. I wonder are the cables better? I've calc'd is takes about 18/19 hours to charge at mine and at least 22 hours at hers.

    Different voltages will affect it but in general you’re only getting about 10a from the granny cable. Plus running the risk of burning out that socket from constantly drawing 10a for prolonged time frames.

    A CP is 32a with generally a 40a RCBO so much safer in practice.

    Each to their own though. Your Leaf would charge at 6.6kw on a charge point of 2.3ish so would charge a lot quicker if required.



  • Moderators, Home & Garden Moderators Posts: 7,022 Mod ✭✭✭✭graememk


    The granny cable could be cutting out due to temperature of the plug,

    If the granny charger is overheating, check/replace it the actual wall socket could be worn/corroded/loose/etc especially if it's an outside one.



  • Registered Users, Registered Users 2 Posts: 10,032 ✭✭✭✭CoBo55


    Nothing strange in my case. Granny charger max rate is 10A/2.3Kw per hour which means it takes almost 6 hours to fill an empty 13Kw battery. When I got a proper CP installed the car was charging at 16A/3.6Kw per hour(the cars maximum rate of charge) reducing the 13Kw charge time to a shade over three and a half hours. With my full EV the charge rate is 7.3Kw per hour taking almost 8 hours to charge an almost empty battery to full, that same charge would take over 22hours with a granny charger 🥴. It would be like a breast fed baby, never off the tit🫣

    “It would be like a breast fed baby, never off the tit”

    This is my new explanation of the difference between granny charging and charge point installation 😂😂



  • Moderators, Society & Culture Moderators Posts: 42,202 Mod ✭✭✭✭Gumbo


    I have a 7.5m cable that I removed from a dead Tesla Gen 2 charger.

    It’s type 2, 3 phase, 22kw capable. Has the Tesla button for the port obviously.

    Is it worth anything?



  • Moderators, Society & Culture Moderators Posts: 42,202 Mod ✭✭✭✭Gumbo


    I see the GivEnergy have launched their EV Charger. Integration into Giv Energy products I assume.

    My inverter and battery are Giv Energy so it will be interesting to see how they price it considering their statement is “Affordably priced, to make clean electric charging accessible to all”

    Folks, anyone any experience of the Ohme Home Pro wall box?

    Was originally going with a Zappi but after reading many stories around reliability as well as problems with BMW EV software I think going with the Ohme is a safer bet.



  • Registered Users, Registered Users 2 Posts: 8,128 ✭✭✭youcancallmeal


    Is zappi the only option if I want to be future proofed for possibly getting solar panels?

    Are there any concerns with having an air source heat pump and charging an EV at the same time? Will an EV chargers load balancing handle that?

    Also maybe a stupid question but can an air source heat pump be used in some way to aid car charging?



  • Moderators, Society & Culture Moderators Posts: 42,202 Mod ✭✭✭✭Gumbo


    Neighbour has one. No complaints so far but I do know he had awful trouble getting it to charge his MY at 32a. For some reason it was stuck at 16a. Installers had to come back out. The unit was set for 32a but it wouldn’t work. I’ll find out the current status.

    Wallbox is another option that works off WiFi instead of a data sim in the OHME but OHME have dedicated Irish based support staff.

    1. Wallbox, zappi, Ohme, Giv energy, Hypervolt to name but a Few.
    2. the chargers will load balance to account for the hp draw.
    3. not that I’m aware of
