comfort level maximum is limited on 1P to 3300 W #150

For some reason, the comfort value maximum is limited to specific values. For example, below I can set the value of the comfort anywhere below 3300, but I can't set it to anything higher. Oddly, as you can see from the history, I could set it higher earlier when the vehicle was charging.

If I restart the integration, the slider seems fine image

but when I do this image I still get this image

and when I do this image It would run, but the slider would max out at 3300 image

turn on 3 phase?

JanDetrez commented 1 month ago

oh good catch, I switched it off yesterday with some testing. Solved 👍

I have my Alfen an Load balance limit at 32A, how come it was stuck at 3300 W? I should be able to go to 230V*32A= 7360W

leeyuentuen commented 1 month ago

maybe I need to check the code later, perhaps I missed the check on the 32A license and only checked on the 1to3Phase option

Would be great, thank you :-)

use case is that I use your plugin to implement a power limit, which sits arround 4.5 kW (to accomodate the capacity tarifs in Belgium...). To limit the power, I use comfort mode and let an automation define the comfort level, hence limiting the total power draw of the Alfen. Considering 4.5 kW is at the edge of 1P/3P switching, I would like to force the Alfen to use 1P, and set the comfort level anywhere between 1.4-4.5 kW, depending on the total load of the house.

(the ampere load balacing limits from Alfen don't work for limiting power when using a 3P system, because the amps can be imbalanced across the lines)
