I have a little problem, and not sure how to handle.

In Modbus you can set a max A for charging (like the select we have with 6-63A).
But I can not get this value back from the charger. I can get back the max value, I instead get back the max value that it uses based on the car etc

If i select 8A it can send back 6A and so on…

Not sure how to handle this yet…

EDIT:

I can handle it so that i keep what we set in Homey and use that - but that does not guarantee the value - it can be set by another integration / app and Homey won’t know about it.
Homey set it to 8A, and that is what we use etc. but then if you use another app and set it to 16A Homey wont know and our UI and so on still thinks (and in some cases set to 8A)…

Ok, so status now.

I have added ev charger / energy so it should show up for those having that function (I cannot test myself)
I have added “P40” support, via Modbus (this also works fine for P20/30, thinking I will change those to use modbus later - much easier and less problems can arise).

For the modbus version, there are 2 changes to how the P20/P30 works

There is no onoff (suspend) - no support to set for P40 (works in P20/P30) and no way to read if it is suspended or not.
the “Charge power” is set when you select it (or initial to what your hardware has as supported), but we cannot read the actual value set on the machine so Homey will act somewhat as master and set this on intervalls based on what is set at Homey.

If anyone want to test it, and give any feedback or such I have submitted a test version.
(note, you need to manually add your IP for now, I have not yet added the MAC address for P40)

Welcome back, Jonathan!

Now the Kebas show up in the energy tab, thank you! (I guess that can be done for the Renault app as well ;))

May I suggest to keep UDP for the P20/P30 and only add Modbus for P40.
I understand it would be easier for you. But the UDP interface is absolutly rock solid. It never misses a beat and it is unlikely they change that interface for P20/P30.

You have done an amazing job and I do not want to see that being crippled by the missing functionallity in Modbus.
Also I rely on that functionallity in my automations for load balancing.

I have flows using Energy Total tag for calculation. They all broke with the v1.1.15 update.

On 2 of my 3 Keba P30s, I could replace the broken tag with a new. On the 3d, Energy Total was not present.
Missing

Exist

Will try charging later today.

Jonathan_Cohen · March 25, 2026, 9:39am

Thanks for the feedback!

I will keep the P20/P30 as today.

Note, a user with P20/P30 can still use the P40 just fine, if he/she wants to use modbus version instead (maybe it should be called Keba UDP and Keba Modbus as devices instead, but a but technical names…?)

Jonathan_Cohen · March 25, 2026, 9:42am

Strange, I will check this - hopefully later today.
To be able to add to energy-thingy I needed a “meter_power” capability that would have duplicated the already existing capability… so it is removed but should look the same and exists as an option.

Jonathan_Cohen · March 25, 2026, 2:36pm

Have you tried to restart the Keba APP (i guess it already have, because of install), it is in the INIT it registers the capabilities (and removes old ones).

You could else try to send a diagnostic report directly after restart and I could see if I can see aything.

When I check both P30 and P40 at home I have the “Energy Total”

Do you see it in capabilities and/or in statistics correct for all chargers?

EDIT

@aste there is a new version for testing, some clean up but not sure if it will help..

Else I think i need to add the old one back and follow this guideline to let it work, but not use in the APP UI (in parallel) - strange that it works for some of the devices for you…

aste · March 25, 2026, 9:29pm

I just got the update and now all 3 was populated with Energy Total. I repaired my flows and will charge tonight.

Jonathan_Cohen · March 26, 2026, 7:21am

If no more things found…

( Please run the test app and come with feedback @_Gesperrt @Daniel_Lenfort @Roland_Brandmayr @Gabriel_Kreutzer, install it from Keba | Homey )

I will just wait for Homey to design some nice icons, ref: se.cohen.keba · Issue #386 · athombv/homey-vectors-public · GitHub before releasing the app.

If anyone in this thread are good designers they could chip in and do 2 icons following Homeys guidelines

Hallo Jonathan, vielen Dank für deine Arbeit, ich kann dir leider nur mit Bildern helfen da ich keine Ahnung habe was du machst. Also Garage ist auf keba wird auch erkannt. Mehr kann ich noch nicht sagen da das Auto erst später nach Hause kommt.
