what are the supported chargers and cars?
I cannot add my EV’s and my chargers
I have 2 Wallbox pulsar plus and a Audi and Mini SE. All of them are configured in the Homey
best regards

Hi Rien,
All supported devices are listed here: Ondersteunde apparaten — Ultimate EMS
Your EV’s and wallboxes are supported as well so that should work.
But did you added the EMS devices after installation of the app? This is the first step to take.
After this you need to select your devices and configure them, then optionally add the widgets to your homey app home page.
I have the exact same issue, did you manage to solve this?
Thanks for letting me know, please the new test version that has a fix for this issue.
Let me know if this works!
What happens if you click “ga door”?
Tried many things, but problem remains the same
Hi Rien,
Sorry for the slow reply, and thanks for trying so many things.
I looked at what the pairing wizard did up to 2.5.112, and it doesn’t fit your setup (2× Wallbox Pulsar Plus, an Audi and a Mini). It offered only one EV list, filtered on charger brands, so a car like your Audi or Mini wouldn’t show up. It had no separate charger field and no second EV.
Version 2.5.113 replaces the wizard. Step 5 (“EV and charger”) now has, per EV: the car, battery capacity, the charger, number of phases and max charge current, and a button to add a second EV. Adding a car is optional and read-only; it’s only used for the battery level. Your Wallbox works through the community app “Wallbox Charger” (nl.xseth.wallbox): on/off is direct, and changing the charge current needs a Homey Flow (“EMS wants to set EV charge current” trigger, then the Wallbox’s own current action).
Once you’re on 2.5.113: Devices → Ultimate EMS → ⋮ → Repair, and go to step 5. I can’t promise it fixes your case, because I never found out where it goes wrong for you. If it still fails, could you tell me:
- Where it fails: the pairing/repair wizard, or the settings page (EV section)? What does the dropdown show (empty, or your devices missing)?
- Which Wallbox app you use in Homey (app name or App ID).
- Whether you’re on a Homey Pro and which Ultimate EMS version.
- A screenshot of the empty list, or of the device’s capabilities in Homey.
Hi Richard,
Thanks for testing 2.5.112 and for the screenshot. Since it didn’t help, we know the waiting time wasn’t the cause.
In 2.5.113 I changed two things. The first check no longer waits (it asks again after 1 second and continues after 2). All wizard screens are also protected against the “Next” button call failing on certain Homey versions. That is my best guess for what happens on your iPad, but I can’t be sure yet. On top of that, the wizard itself is rebuilt with more steps, and every step can be skipped.
Could you try adding the device again with 2.5.113? If it still hangs, these would help me:
- Does tapping “Ga door” do anything, or is the screen completely stuck?
- Are you using the Homey app on the iPad or the web app (my.homey.app)? Does it behave the same in the other one?
- Your Homey app version, Homey firmware and roughly how many devices you have.
- After closing the wizard and reopening the Homey app: can you open the Ultimate EMS settings page? If that loads fine, the problem is only in the wizard.
Thanks!
Ultimate EMS 2.5.113
- New pairing wizard (8 steps):
- Grid connection: P1 meter, phases × amps, fixed or dynamic contract with price source.
- Solar: read device, optional separate dim device, peak power and peak hour per inverter.
- EV and charger: up to 2.
- Home battery.
- Heat pump or boiler.
- Summary.
- Every step can be skipped and filled in later. You can add more than one inverter, battery or device.
- Repair (Devices → Ultimate EMS → ⋮ → Repair) opens the same steps with your current settings.
- Fixed: the wizard’s first check no longer waits long, and it handles Homey versions that treat the Next button differently (some iPads).
Hi Menno,
After updating these are the results
1

4 the app settings i can open, repair device gives unknown error getting file
the is the diag report: 8e231d73-e16d-4a5a-b5ef-c4cc7a2303c5
hopefully this helps.
I get the same screens
Ah yes I can now also see it happening at another user…
I have made a small update to try to isolate the issue. Please try it and let me know what happens
Gefixed!!! At least… in my setup! thanks for being patient and helping to solve the issue!!
Please let me know if it has resolved in your case as well!
gefixed Rien!
I can now install it, i will play around with it.
P.s. how can de ems tell what battery is used as I don’t see any settings for the battery brand
Perfect!! The Ems reads the capabilities from your battery app and uses this to read en write to it. So no config needed, direct communication. In most cases it works like this, as a last resort I sometimes need to revert to flows but I’d like to prevent that route as much as possible.
