Easee also has an 'Equalizer' to throttle the load of the main fuse. With homey you can postpone the charging depending on the price etc.. So you don't have to use the tibber tool to measure the load on the main fuse...

[@propergander8509]

The Easee Wallbox works with this free German solar surplus charging service called “Clever PV” as well If your inverter or home battery is supported, you can pretty much avoid charging with grid power at all for most of the year and avoid pretty much gifting away your solar surplus for prices far below market rates. Mid-February to mid October in my case here in Germany, save for the handful of weeks where there isn’t a single day with a few hours of sunlight. Thanks to CleverPV, I’m making even more efficient use of my solar array, helping it pay itself off much quicker. Also, nothing beats the feeling of kissing fuel costs goodbye and driving essentially for free, at least with no running costs for 7 months of the year!

[@YvesWinkel]

Great video again Bjorn. We've got also the Easee charge robot (In The Netherlands) and Tibber is available. So probebly next year, when it's time for me to contract a new energy supplier, they will be the winner. Thnx again. Keep up 🙂 Greets from The Netherlands

[@fredrikfriisnielsen6243]

To clear up the confusion around our Norwegian electrical system. Bjørn has 3 phase 230V IT, which does not have Neutral. The reason tibber only reports the amps on L1 and L3 is because the energy meter does not read L2. The phrase single phase or "enfas" is technically incorrect on an IT system. It should be two fase. On a 400V TN system single phase would be correct, because you use one phase and neutral. I understand why the terms are mixed up since the fuses look the same. Usually EV charging on 230V IT is locked to two phase, since EVs are usually not made to recieve 3 phase 230V. However I always install 3 phase to the charger so that the charger has the option to switch which phases its using depending on other loads is the house if the system supports that feature, which Easee does.

[@christianortendahl7537]

Well, this is one area where country differences in electricity standards are very obvious. In Sweden, three phase charging is the norm.

[@Gazer75]

Yeah its only like 2-3 countries that use IT system AFAIK. We had 230V 3-phase with a 63A main fuse where I grew up. I think my dad had a lathe or some other machine with a 3-phase motor, so the house got fitted for it when it was built in 76. Most new areas in probably the last 10 years have been getting 400V at home. Basically if they have to put up a new 22(11)kV substation and build a new LV grid in the area.

[@vonnekueste]

We use tibber since 2020 in Berlin / germany. It‘s really cool and works great.

[@rolandrohde]

Is there a way to see Tibber energy prices over time without actually having Tibber contract? I would like to check whether I could actually save money with Tibber by putting cheap electricity into my solar battery, Tesla and heat pump...

[@bartvanhoof6278]

For those in Spain ... Wallbox provides a load balancing solution with their home chargers (called Power Boost - we have a Pulsar Plus) ... it works like a charm. No phone app, but the "fuse" has a digital display where you can read the current power consumption. My example ... 240V, 24A single phase house supply (the max. our apartment can take ... upgrading it would be very costly ... and this is good enough for us) ... we are on a fixed rate of 0,03€ / kWh from 1am - 7am (outside that 0,30€) so could theoretically charge. max of 34 kWh (approx.) during the cheap rate (half the car battery - we don't charge every night). Both the car and Walbox unit allow for scheduled charging. Sometimes we run the dishwasher or drier during the low-cost hours. But there are usually no high-power appliances running at that time ... however, that might change in the future. Anyway, whether it be Tibber or Wallbox or another similar solution, I highly recommend load balancing, especially if you are doing your charging during the day when you might be running a lot of other appliances.

[@bastelbudi]

my car can only charge on one phase too and my stove uses 2 phases so i decided to remanage my fusebox to clean phase 1 from each heavy load. so i can use phase1 for just the wallbox and small other stuff. helped a lot to get the maximum out of my house. i have 50A fuse before the messure unit and 35A as my main fuse.

[@MichaelEricMenk]

Tibber also connects to Home Assistant. Home Assistant fetches prize and power usage (from Tibber Pulse) and preform it's own logic... The relay you se connected to the water heater uses Z-Wave, and most likely the thermostat also. The electricity prices in Noway is charged by the hour. Today the price where I live is 1000% more expensive at 8AM compared to 4AM. So the relay do no save energy, but maximize the use of cheap energy..

[@BeardedTechFoodGuy]

The Aeotech heavy duty smart switch is only a smart switch and not a thermostat. It has absolutely no idea about the temperature of the water inside the tank. And, the Homey of course has the same possibilities as Home Assistant.

[@MichaelEricMenk]

@@BeardedTechFoodGuy The system know when it is hot due to the energy and power monitor inside the switch.. If ( (boiler-relay is on) and (amperage usage less than 4) ) then〔 water is hot. 〕 If this water heater has a 2kW element it will go from cold to hot in about 7 hours.. The system can learn how much you normally need to fill it up with heat once a day.

[@titanium70rd64]

Awesome. Tibber is also starting in Germany. I’m switching to Tibber from January 2023 on. I’m excited as this imo the future in our electric system(s)

[@DouglasJMark]

Nice. You control your home's electricity as adeptly as how you control a Tesla display! My head is spinning again 🙃

[@MichaelEricMenk]

Tibber can also connect to some cars and fetch the SOC. It then calculate when to start charging in order to get the cheapest prize and get the car to your preferred SOC.

[@DouglasJMark]

@@MichaelEricMenk interesting. Wonder if we’ll get it in Canada?

[@MichaelEricMenk]

@@DouglasJMark The reason Tibber has this feature is because in addition to be an energy broker, they also participate in the frequency market, where they sell power reduction. A customer can opt in having their temperature reduced or stopping EV charging or water heating... Tibber pools multiple users and sells fir instance 1MW of power reduction for X number of time. Tibber is therefore integrated in the power system in Norway and Sweden, and will not work outside their area of operation... But a lot of cars have open API, and you can connect to the API and controll the car. But thats not for a end user. If your rate is connected the the spot market, then you will have to get the prices in a computer readable format. If you do not have a car API, you can get a EVSE with an API, og a relay on the power cable. You then have to spitt ball the needed consumption of the car for the next day. You can use Home Assistant to control a number diffrent relay.

[@mikaeloverby]

I use homey, tibber and easee home as well. Best combination!

[@gelisob]

This can also done in an "analog" way by using timed power relay in the house fusebox. With the logic being "when certain household phase exceeds x amount, turn off car charging plug for y amount of time" and after set time passes it rechecks.

[@MichaelEricMenk]

4:20 "This is the weird Norwegian system" No Bjørn, you are incorrect. You are not connected to 230V three phase IT/TT . The only way to get what you are seeing on the screen is if you are connected to two of the phases on a 400V TN supply. If you were connected to L1 and L3 on a TT or IT connection, the two legs would have the same amperage. A third possibility is that Tibber Pulse or the smart meter due to an error do not se one of the phases, but I would consider this last one highly unlikely...

[@slijkhuis]

Awesome video! I hope you will also do one in the future with a Zaptec Go in combination with Zaptec Sense. Reason why I am asking is that where I live i never pay more than 0,51 øre per kWh. However, recently all power companies changed their ‘nettleie’ (nett usage) with insane prices for high ‘peak’ usage, stating EV’s as reason. That zaptec sense device is connected in your fusesbox at home, and it should be able to see live ‘home’ usage. So if you would set 9.9 kWh max usage (to stay under the 10 kWh peak. It should manage to communicate go the charger and lower & rise the power in realtime. It also can connect with Tibber for the power pricing too. However, for me, the ‘peak power’ is the thing that is interesting. But maybe also in Oslo the nettleie is a thing, so you could ‘manage’ both. So does this Eassee (Pulse) also support that you can state a ‘max. Total home usage’? The norwegian weird powernett is IT (230v 3-phase) instead of all of europe that uses ‘TN’ (400v 3-phase), all new neighbourhoods get the TN access. You should then be able to charge your car with 22 kW if the car allows it ofcourse! (Get the millenium falcon! 😅)

[@frodeholmelid847]

Hi Bjørn . As Tesla can charge on 3 fase IT I would check the settings in the Easee app to see if it is locked to single fase charging. They do that as a default setting because most cars don't support it. I charge my Tesla on 3 fase IT. You then need less Amp for more kW. Looked like you had a 3 fase circuit for your charger. Just remember to put it in auto or single phase when you charge a car that don't support it later.

[@catober1]

Was thinking to comment the same. At lest you can do less load on phases if you have smal fuse like him

[@Kronospace]

That is crazy cheap electricity, roughly 10x cheaper than the UK

[@CarVisionDE]

Whats the Price in NOK? in Average per kwh in norway?

[@iambenmitchell]

Pretty cool. I'm hoping to get an EV next year (MG 4) and I hadn't really thought much about charging while other appliances are on. I don't think it will be much of an issue in my house though because our cooker is gas and so is our boiler. Biggest load I think would be our Kettle and Microwave which can both pull 2-3kw each I think. Edit: I am in the UK so 240v/50hz single phase. I could get 3 phase at home but I think that would cost £10,000 or so to do

[@winyettyu]

Dont worry, I have 1x32 amps in my house, I charge at night from 23:00 until the morning with 1x16 amps and I havent had any problems. I thought about getting a load balancer and a wallbox so I can charge faster if the house doesnt use a lot of power, but I dont see the point in it yet. If my GF will swich to EV, than maybe it is a good idea.

[@OlavAlexanderMjelde]

In Norway we pay two part of an electricity bill: usage + a fee for "line loss" that is called something like "renting power lines". The "renting power lines" fee is also two-fold: based upon power unit price, but also based upon the "capacity part". If you average a consumption 3 times, that peak power will add to your bill. So in my City (the prices differs in different regions), it is like: 6 steps (0-2, 2-5, 5-10, 10-15, 15-20, 20-25). Prices then jump 125, 206, 350, 494, 638, 781 per month. So lets say the power is like 2kr/kWh one day, then in the night it is like 0.1kr/kwh. Then you go higher in the capacity and pay more "renting power lines" fee, but since the price difference is so high, if you charge too slow, it means that you can also loose out on cheapest hours. But if you just charge to the max, 11 kWh, on top of this your house will pull power for heat pump, lighting+++. So if you are unlucky, your water heater will then maybe pull 2 kWh + maybve you cook some noodles, heating turns on. So this might get you into the step 5 if you are very negligent. If you do however just set the car to use max lets say XX amps, you can for the most of it limit to for instance the 5-10 capacity step. But with tibber you can in reality load balance your stuff, as it can read from the meter how much your home is pulling. And then you can just think what bracket you wish to land in, so if you want 2-5 kW, you can do it without planning too much

[@iambenmitchell]

@@mrm1885 shut up. A Tesla is double the price and not much better than an MG for what you pay for. Not to mention a Tesla is impossible to insure at my age. The Chinese cars are much better priced, come with loads of features standard and are much more suitable for most people. They’re here to stay and you can hate that as much as you want until Tesla make an affordable car

Octopus Energy in the UK offer special car charging electricity plans, the simple 01:00 to 07:00 and one which requires specific wall boxes and vehicles (Tesla...). It will charge the car at any time of day that there's enough renewable energy in the grid that you get cheap electrons. Doesn't care about load-shaping in the house though, which is the problem you have

[@FSHelgeland]

This works flawless with 400 TN.

[@emceh]

Isabel helped and woke you up?

[@petersort2192]

Here in the UK a 100 amp single phase supply is pritty much a standard, 45p per day is the standing charge and 35 per Kw hour, you can get 3 phase and that would give you 300 amp over the three phases so you guys in Norway are pritty restricted

[@96Lauriz]

im pretty sure 3x100A would cost fortune to upgrade to and costly in standing charges or other fees that it is not considered standard in UK. here we have 3 phases so we dont need thick ass cables, weird looking meter tails, ring circuits, fuse at each plug and what not. Copper is expensive these days. It's all bout cost efficiency.

[@rcarhouse]

👍👍👍👍

[@christianortendahl7537]

Not load balancing, just load limiting. But works reasonably well - have the same combo myself. Never blew a fuse (six months in use).

[@zaarkeru3391]

yeah, one would need true VtG in order to do load balancing. but that is comming, and is some really cool tech. the grid of the future is going to look very different from today.

[@OraEtLabora0]

🤔3:18 can you not get supplier to upgrade your main fuse to 100A, like in UK they do?

[@Yggdrasil42]

That's usually quite expensive. Here in The Netherlands the standard is 3x25A. You can upgrade to 3x40A for an additional €600 per year (plus €1000 one-time). Higher ratings are of course more expensive. So it'd have to be worth it do invest that much.

[@flox8342]

on Tesla you can actually use the cars current throttle instead of a wallboxes limiter with tibber 👍🏻

[@bjornnyland]

But it's not automatic.

[@CarVisionDE]

@@bjornnyland yeah there are software interfaces possible to do that so the software automaticly adjusts it via tesla api

[@ErikMeike]

I am surprised that your whole house breaker is 32A for two phases. My house in the US has two 120v phases with 200A (up to 48KW usable power, 38KW continuous to a single 240v device). That would be I think the equivalent of about a 100A fuse for your voltage. Do you know how common your setup is?

[@Danjon1235]

i have a terraced house in Sweden, we have a 20A fuse... Three phase to the charger that can pull 11 kW.

[@kentfusag5458]

What in a house could possibly pull 38-48kw? :)

[@christianortendahl7537]

You electrified America too early, before the rest of the world realized that 230 volts three phase makes more sense. Low voltage, more current, beefier fuses for same power.

[@96Lauriz]

Denmark norm is 3x25A or 3x35A in some houses. Our appliances, especially HVAC is much much more energy efficient than in US. It is normal here to run houses of up to 5000qft even with electrical heating only (heatpumps) with 3x25 or 3x35a fuses. And still some capacity left when using load balanching charger for EV. ;) Yes we do also have houses further up north with very cold climate (-20, -30C) despite that you will not see 100 fuses and certainly not 200.

Worth a read: uk government national smart charger policy where the goal is to avoid overloading the entire country when people get to work, home, or even at 01:00 when the electricity gets cheaper. They don't mandate "every device has well documented API which apps like Home Assistant can use" -that you need to do your own research www.gov.uk/government/consultations/electric-vehicle-smart-charging
