Change limits of parameter

[Di3KLiNg3]

Inside the GO-e app there is the parameter "Zielwert Netz" in the category "PV-Überschuss". Typically this parameter is set to 0 or -200 to tell the charger to regulate the grip point to exact 0 when there is PV in your house grid. This way, only pv excess gets charged in the car

I found an additional usecase for this parameter which works great too.
For my usecase the parameter is set to 20000. This exceeds the limit of the home assistant parameter. Therefore i need to set it up inside the app directly.

It would be great if the limit could be adjused (right now the home assistant limit is -5000 - 5000 i think)

Here are details about my usecase of the parameter:

In my dynamic energy contract, I typically have cheap energy costs in the night times. In the winter time I use these low costs to charge the car or run the dish washer or the wasching machine etc.

Now that i have 2 cars and 2 chargers, it can happen that I exceed the power limit of my house installation point. My fuses only offer me 35A. This allows me a total of about 24kW.

If both cars are charging and the house consumes a lot of power too, this could blow up my main fuse.

For this case i set the parameter to 20.000. If now consumers in the house gets switched on, the charger of the car reduces its load. This works great and i would recommend this to anyone how has similar setups ;-)
(if anyone wonders why 20000 and not 24000 - my house consumers do not load my grid symetric. Therefore i needed to keep some safty margin otherwise on phase could exceed the 35A even if the total power is below the 24kW)

While adjusting the code of the limit of the pgt NumberEntity can be done in 2 seconds, I wonder if the also available Lastmanagement would not be the appropriate place to handle that? Or am I completely wrong and Lastmanagement is just part of evcc?! [I have to admit I am just lost in too-many-ha-integrations]

You are right. But as far as I know, this requires the other charger to be a go e charger too.

The other charger is a different brand and doesn’t provide a function like that. My plan was to limit only the power of the go e charger as this is easier for me to manage. (Maybe I’ll upgrade the other charger eventually, but for the moment it seems like an unnecessary invest ;) )

just for my curiously, would the “lastmanagement” also respect my house appliences?

I don't have a single clue, how the build in Lastmanagement is implemented in the go-e firmware - that's a question that must be asked the vendor... But probably your assumption that this only works in go-e-only scenario is quite likely. But again I do not have any details.

The quickest solution for you is to locally edit the file /custom_components/goecharger_api2/const.py and modify there the 5000 and -5000

ha-goecharger-api2/custom_components/goecharger_api2/const.py

Line 545 in a9f9350

native_max_value=5000,

save the file, restart HA and your Entity limit is adjusted... Since I don't like to make another release "today" just cause of this tiny adjustment that's requested by a single user (and it's not really a bug, that must be fixed)

[marq24]

nevermind - since I was forced into another update - I made the adjustments in the code already

great work! Thanks a lot.

I apprechiate the hint were to adjust it anyway. Maybe this will come in handy for me another time... ;)
