    Tesla Wall Connector load sharing protocol

    @Steffen75D Im not used to python codeing but it should look like the following... m = re.search(b'^<LL control=\".*LeistungPV/state\".*value=.([0-9]*)', greenEnergyData, re.MULTILINE)

    Tesla Wall Connector load sharing protocol

    Lets assume the following situation: Charge limit on car set to 80% Car is charged by less than 80% TWCManager is set to only charge with Green Energy, but nothing available to charge (e.g. no sun, at night) Would the car ever go to sleep? I have the feeling that this is not the case as the...

    Tesla Wall Connector load sharing protocol

    In winter, I have the TWC running on one phase only. In summer I modify the script again (to charge with solar power only) and switch to 3 phase usage. The car itself is using one phase only if it comes close to 100%. Though, I think this decision is done by the car and can not be controled by...

    Tesla Wall Connector load sharing protocol

    @Bulldog well "max power" is crawled from TWC Manager and as far as I read it's possible to access that data eaisly via a http-call. So yes, should be possible quit easily.

    Tesla Wall Connector load sharing protocol

    @CDragon thanks for getting back to me. I have changed some lines in your code to take an alternative USB device once the original failed. That worked very well as a workaround so far. No more problems even though I don't think my way is a good one to handle it. I will probably get another...

    Tesla Wall Connector load sharing protocol

    All was working fine for weeks but recently I got a problem, not really related to the script but more to the serial-to-usb driver it seems: [18830.252081] usb 1-1: USB disconnect, device number 3 [18830.252457] ftdi_sio ttyUSB1: error from flowcontrol urb [18830.252930] ftdi_sio ttyUSB1: FTDI...

    Tesla Wall Connector load sharing protocol

    @CDragon Im not sure if its OK or even wanted to post suggestions here, but I try... Save history of all charges made (date/time + greenEnergy + "how much charged"). That way we would always know how much we charged at home today/this month/year... I think this would be a great feature to...

    Tesla Wall Connector load sharing protocol

    Thanks @Nietschy :) Would have been great is the protocol would also manage this and decide how many phases it uses. As far as I remember, at the end of the 100% capacity, either the car itself or the TWC decides anyway to only use 1 phase of the 3 as it can not load that fast anyway.

    Tesla Wall Connector load sharing protocol

    Since yesterday, I am a proud owner of the modification from this thread. I run into some problems but could solve most of them myself. 1. The suggested USB RS485 component comes with 6 wires cable but the colours to use are not black/red but orange (D+) and yellow (D-). Someone might mix that...
