Dag Rob,
Kan jij je paal handmatig dan instellen op een lager laad vermogen?
New: an “EMS Today” summary on the daily chart widget showing today’s self-consumption (kWh, and the % of your own solar you used yourself) and the average price you actually paid per kWh today, including the benefit of your own solar.
New: an in-app FAQ on the settings page answering the most common recurring questions (EV charger “status unknown”, why the EV charges to a different % than expected during a trip, why the battery doesn’t fully empty/fill, what “basic configuration incomplete” means, zero export vs. zero import, where to find a setting, and how to see what the EMS actually did) — falls back to a forum link when your question isn’t covered.
New: chargers that can only be turned on/off (no adjustable charge current/power) can now be marked as a “fixed power” charger with a manually set kW value, so the EMS can plan and decide around it correctly instead of assuming it can throttle the charge rate.
Fixed: a cheap-price quarter could still start EV charging during the night block even when night-charging behaviour wasn’t supposed to allow it that night.
Fixed: on some P1/smart-meter integrations, the P1 meter didn’t show up at all when adding the EMS Controller device, blocking installation — the pairing wizard now falls back to showing all devices when the automatic filter finds none, with a manual “show all devices” option as well.
Nee de ev charger doet dat automatisch wanneer ingesteld op overtollige zonne energie, maar daarbij wordt geen rekening gehouden met bv een autonome batterijen
Dag Rob, internet zegt dit: Mogelijke laadstanden
In de mySolarEdge-app kun je de manier van laden op elk gewenst moment aanpassen:
-
Snel laden (Max Vermogen): Laadt de auto met het maximale beschikbare vermogen (tot 11 kW of 22 kW, afhankelijk van je aansluiting), waarbij stroom uit het net én van de zonnepanelen wordt gebruikt.
-
Beperkt / Lager vermogen: Je kunt de laadstroom (in ampères) handmatig verlagen in de app (of laten begrenzen via de SetApp-installateursinstellingen). Hiermee voorkom je bijvoorbeeld dat je hoofdzekering overbelast raakt als je tegelijkertijd kookt of wast.
-
Overtollige zonne-energie (Solar Only / Eco): De laadpaal past de laadsnelheid dynamisch aan op basis van de stroom die je zonnepanelen over hebben en die anders aan het net zou worden teruggeleverd.
Zo verlaag je het vermogen in de app
-
Open de mySolarEdge-app en ga naar het tabblad EV Charger (Lader).
-
Kies de laadmodus of pas de slider/laadstroom aan naar een lager amperage (bijvoorbeeld verlagen van 16A naar 10A of 6A).
-
Sla de instelling op; de laadpaal knijpt direct de stroomtoevoer naar de auto af.
Controleer na het aanpassen van de instelling in de app of het laadvermogen op het dashboard van je auto of in de app daadwerkelijk is gedaald (bijvoorbeeld van 11 kW naar 3,7 kW).
No, I don’t have a battery.
That kind of flow would work well in this situation I think. It’s a bit more straightforward than the planner for this kind of things.
its already in the test version I released today so let me know if it works!
I’ll test it tomorrow. Also a test as to what happens when the car isn’t home yet when the flow starts.
Probably it will not charge the car… if so let me know because then we have made something magical! 
That would be magical indeed! I meant what would happen when I plug in the car afterwards, but before 1600. 
Hi Arne,
Ah yes that would be a nice test! since the flow is not commanding the EV directly but controls an action on the EMS it should follow execute the charging when plugged in.
Today I gave this app a go, because I want to combine charging of a Marstek Venus E 3 and two electric cars. Is there somewhere to check which actions are performed by the EMS automatically and which require a flow in Homey to trigger an action?
What is the correct way for adding a second car? Both cars use the same charger at home. Do I add it as a second vehicle profile on the first car or as a second seperate car? The guiding text seems to indicate that I should add it as a second profile to the first car/charger.
So far I’ve tried both, but I can’t really find the second car in any widget or the online dashboard.
Any help with this would be much appreciated.
The setup looks very clean and much simpler than the Slimladen app I used until now to manage the Marstek but is getting overcomplicated. So compliments for that!
Hi Mantlet,
Thanks for the compliments!
I had a look at your question and you are right, it was unclear how to add the second EV. Old procedure was to add 2 profiles. I changed this in the new test app, settings are now much better to understand if you have more than 1 EV. please see my next post in a few minutes with the new test version.
Let me know if it works out for you.
Ultimate EMS v2.5.3
Fixes
- PV peak-power settings are now capped to what your grid connection can actually deliver per phase (amps × 230V, with margin for legitimately oversized panel setups). On a 3-phase installation with a PV meter missing on one phase, a peak-power value entered in Watts instead of kWp (an easy mix-up) could inflate the live “unmetered solar” estimate to tens of kilowatts, corrupting real-time solar-surplus decisions for the battery, EV, heat pump and dump load. Now capped, both for this live estimate and for tomorrow’s forecast.
- The EV widget’s vehicle-profile switcher (for one shared charger with multiple cars) now treats your already-configured EV settings as an implicit first profile. You only need to add the car(s) that were missing, instead of duplicating the first one too.
- A vehicle profile left without a filled-in name was silently dropped when saving — fixed.
- A physical device configured as both a heat pump/airco slot and a boiler slot (e.g. one heat pump with a separate DHW tank) could have its dashboard on/off toggle land on the wrong slot — fixed.
New
- The settings page now warns directly under the peak-power field when an entered value is higher than your connection can handle, so a Watt/kWp mix-up is caught immediately.
Renamed / restructured
- “Second EV” is now called “Second charging point” — that section configures a separate physical charger, not a second car sharing the same one (that’s what Vehicle Profiles are for).
- The settings page now separates vehicle settings (“Electric car”) from charging-point hardware settings (new “Charging point(s)” section: phases, charger device, max/fixed current, time hysteresis, min. on/off time, peak hours, manual postpone via Flow). “Second charging point” now lives as a subsection inside that new section.
- Charging strategy and night-charging settings are bundled back with your main vehicle, with Vehicle Profiles (optional, for multiple cars on the same charger) coming after.
Unfortunately it was a bad test. The car was below the min SOC so it would’ve charged either way. And at 1600 it was still below min SOC.
Afterward I started a plan to reach 80% at 1000. But it never got there, the car kept on charging at 6A untill the 2 hours before, where it ramped up to 16A. But that wasn’t enough. Wouldn’t it be possible to set the amps higher to be able to reach the setpoint? Or, why isn’t it an option to choose your desired min amps for normal charing, when there’s no sun, or when it needs to be lower for load balancing?
Hi Menno,
I have two feature requests for Ultimate EMS 2.5.3.
1. Tibber Pulse phase-current support
The Tibber Pulse is selected as the grid meter. Total grid power is read correctly, but the EMS Controller’s grid L1/L2/L3 values remain at 0. The Pulse exposes these capabilities:
measure_current.L1measure_current.L2measure_current.L3
It does not expose power per phase. Could UEMS use these current capabilities directly for per-phase load balancing and overload protection, and optionally show estimated phase power (current × voltage)? The signed total import/export should remain based on measure_power, because the Pulse does not provide direction per phase.
For example, during a balanced three-phase EV charging session, the Pulse measured approximately 12/12/11 A and about 8.3 kW total, while the UEMS phase values remained at zero.
2. Expose the planned DHW/boiler schedule
I use the same Husdata H60 device as both the heat pump and the SG-Ready boiler. UEMS emits blocked/normal/boosted/max triggers when the SG-Ready state changes, but Homey cannot see beforehand when UEMS plans to heat domestic hot water.
Could UEMS expose the next planned DHW start and end time, the planned SG-Ready state, and the planning reason (for example price, PV surplus or temperature) as capabilities, Flow tokens and/or Flow triggers? This would allow EV charging and other loads to reserve sufficient phase capacity before the heat pump starts.
Thanks!
Good test!! I also know why this behavior was happening and I now changed so that it continuously checkes if it can reach the desired SOC. Update coming soon!
Hi Brian,
Thanks for the detailed feedback, both suggestions make sense and I’ve looked into what it would take.
Tibber Pulse per-phase current
You’re right that this doesn’t work yet. The app currently only picks up measure_power capabilities per phase for the grid meter, your Pulse only exposes measure_current per phase (L1/L2/L3), so those end up unmapped and show as 0. The fix is straightforward: fall back to current × 230V as an estimated per-phase power when no direct power reading is available. That’s on the list to implement.
Exposing the planned boiler/DHW schedule
This is also doable, and more than that, the data already exists internally. The app currently plans boiler/DHW charging in the cheapest hours of the day (price-driven, no comfort-band logic yet), it’s just never been surfaced outside the planning engine. I want to add this as a Flow token (and probably a trigger for “boiler schedule updated”) so you can build automations around it.
Neither is built yet, but both are technically clear and I’ll pick them up. I’ll post back here once there’s something to test.
Thanks again for the well thought out report!
Thanks! With the update this is much more clear. I still have to make the flows that actually start and stop the charging and set the amperage, I’ll look into that tomorrow.
I do have a question about the planning. I’ve set the cars chargemode to Solar + net, enabled night charge and set the car to ‘at home’ all days of the week. The plan now wants to charge my car tomorrow during the afternoon, as I expected.
Now, I add a manual ride to the widget for tomorrow, with a desired charge of 60%. I was expecting the schedule to plan a charge tonight, so I can leave tomorrow morning with a 60% charged car. However, the planning remains at the afternoon, also after manually running a flow to plan again.
Is this expected behaviour or am I missing the meaning of this setting and manual adding rides?
Can I also add a suggestion for a ‘then’ flow card when you have two cars? I would love to be able to use a flow to select which car is hooked up to the charger, so the right plan is created.
I already have a flow that determines the car, based on location and whether the charge port of the car is opened. I use this to start auto charge with the right chargecard (a business card for my company car and a private card for the second car). So I have a flow that could set the active profile.
Hi Mantlet,
Sounds like a plan, instead of selecting the EV from the widget you also want to be able to select it from a flow… I’ll add that to the next update.
You other question about the trip planner, in the background all was working correctly but it did not updated the widget. Also fixed in the next update.
Thanks for reporting!
