Use of Access Bit

[kennyschuoler]

Hi @bobosch , @mstegen ,

What is the desired use for the access bit, is it the purpose to enable/disable charging in general, or only in combination with e.g. the RFID ?
I currently don't use RFID or any other access verification , but i do use the access bit in my automation to disable charging at dynamic moments (e.g. i first let my house battery fully charge on solar, only then i enable access bit ( solar is automatically set at 7h in de morning).
If this is not the intended use, then i will have a look and introduce something similar. If it is the intended use, then i will verify if everything works as designed ( e.g. switching from smart to solar "resets" the access bit)

Thanks !

The access bit is used for enable/disable the EVSE.
It can be enabled/ disabled with:

• An external switch, connected to the SW input and ground.
• The RFID reader
• a modbus command (like you used)
