Kostal Enector Wallbox mode maintained from home assistant

timo232323 · November 11, 2024, 11:02pm

Hehe,
yea I am loving it! Works just perfect. I can do automations triggered by the battery level of my car now. AWESOME!
Is there a way to show the current kostal charging mode? For example if my wife switches it via the kostal Web Interface.
Thanks again. Loving it!

If I got it correctly you want to read the current ActiveChargeMode.
Yes you can poll frequently the state.

It is allready part of the nodes above:

Give it a try.
The 2nd inject mode polls every 5s the current state ActiveChargeMode and places the result in a sensor named sensor.CurrentActiveChargeMode.

Hope this helps!

Again, worked perfectly. You such a legend. Much appreciated :))

No need to answer bc thats just details. But would it be possible to show the correct active charging mode (for example lock) also in the dropdown menu for the “wallbox_active charge mode”. Right now the status could be “Lock” (if chosen via kostal app). The sensor would also show “Lock” then but the dropdown menu for choosing the charging mode would not change.
Hopefully it is understandable.

If ok, you can think about not using the sensor anymore!

timo232323 · November 16, 2024, 9:35pm

It gives me an error.
Any chance to tip you by the way?

ThronRamses · November 18, 2024, 5:20pm

Hi,
could you share the debug results?
Lars

timo232323 · November 18, 2024, 7:11pm

Thx. Using the debug mode helped. Had to rename the helpers to grid, pv, lock, hybrid.
Now it is working :)))
Any chance for a tip if it is not against the policy of the forum. You have been amazing.

kajakaja · January 24, 2025, 3:50pm

Big thx @ThronRamses

Is it possible to build your NR flow with only REST commands? I struggle to implement NR only for the usage with the enector.

The states from the enector can simple be read with modbus (without tls) - so only set the option would be needed via REST. I‘ve no idea how to implement that but this would satisfy my inner Monk.

Klingt doof, ist aber so :P.

kajakaja · January 27, 2025, 12:33pm

For everyone who stumbles over here and want to do this only with HA without implement NodeRed. I‘ve documented the needed steps: GitHub - ohkaja/Mushroom-Stack-in-Card-Multicard-

Big Thx @ThronRamses For reversing the needed calls.

From security side: the Bearer Token wich is generated via transmitting the KSEM password in cleartext via http calls its also an improvement. Its possible to generate a Token for only this scenario. No need for the Password.

leon.wln · May 22, 2025, 8:08pm

Hello! Really beautifully implemented project and it works without problems so far! Unfortunately, except for one small issue and I hope to find a solution here…

Unfortunately, I get an error message “JSON parse error” with every HTTP request Get Node - does anyone have a solution for this? Actually, I’m only interested in the MinChargingPowerQuota and MinPVPowerQuota values read back from the API…

Thanks in advance! Leon
