How to know if car is connected

[Fabien Marchewka]

With The RAPI when sleeping we can't know if the car is connected. Is there a wa to know if car is connected ?

I'd like to have for example an alert at 23h if car isn't connected. But charging start at 1h00

Sorry, but currently, it is not implemented. The way the code is structured, the connection state is not stored when it’s sleeping. You would have to implement a new RAPI command to interpret the current pilot voltage, and return the current connection state.

May I piggyback one simple question. What is the the status code "0" sometimes returned by the $GS command?

[lincomatic]

0 = EVSE_STATE_UNKNOWN

In certain situations, the code temporarily sets the state to unknown until the status is updated, for instance when waking up from sleep or when an EV is disconnected after a fault. The status will be updated in the next loop

I've implemented this exact use case in  my version at https://github.com/Energybrain/openevse-wifi-ui.  I basically created a new RAPI command GL that brings out the volatile flags.  All my changes in the controller firmware is marked with my initials  //bhc so you can easily port it to your code.

Thank you, I will check this version. Perhaps it will be fine to add it in upstream ! lincomatic ?

Sorry, it will take more coding and testing to put it in upstream, and I'm too busy at the moment. I would recommend putting the extra call to ReadPilot() directly into the RAPI command. It takes a long time to run, so it's not a good idea to call it at the beginning of Update()
