Charging Power value issue #7

Closed maccan-tech closed 3 years ago

maccan-tech commented 3 years ago

Hi, thanks for at great custom component. Finally got my first Garo GLB, and got it working in HA.

I have one issue. When the charging session has ended the car is pulling 0,8 amps for a short time. During this time the charging power in Home assistant shows 3628000 W And i am certain my house can't supply 3,6 MW of power :-)

Tell me if i can help in any way to help get this fixed.

Hi @maccan-tech

I'm not doing any power calculation in the component, so the value must be coming from the charger. Have you checked if there are any pending updates on the charger?

If there isn't any updates, and you can recreate this issue when this reading shows could you try to access: http://<ip>:2222/rest/chargebox/status and provide me with the read out. There might be something I can check for to handle this :)

Hi @sockless-coding My Garo charger: Modell: GLBDCWM-T222FC Version: 6.9-146 (no update available)

You are correct, the problem seems to be caused by the Garo charger. Both the currentChargingCurrent and the currentChargingPower show values that is not correct. My house can not supply 800 Amps or 3628000 W.

@maccan-tech the currentChargingCurrent is in mA, so it's probably ok. I added an upper limit of 32kW to current power, and if it gets exceeded I return 0 since something is wrong. The fix is available in v1.0.4.

I haven't seen this behavior, and I'm on 6.9-146 as well, but I have a GLBDCM-T222FC

@sockless-coding thanks a lot. That will be great. I also sent Garo a email to se what they have to say about the high power value.

maccan-tech commented 3 years ago

Got a response from Garo. It is a bug that will be fixed in a software update. Your workaround works great until they fix the bug.

@maccan-tech Ah good to know they are fixing it :)
