Meter reading values without transaction #615

Closed untouch68 closed 3 years ago

untouch68 commented 3 years ago

Hey,

first of all, awesome project! It helps me a lot for development!

My problem that I have is, when the EVcharger is connected and I start charging SteVe only shows me the connector status as "available". If I use the option in the OCPP commands with Start Transaction, it shows me that its charging and tells me meter readings etc in the transaction.

But how do I get the current meter reading of the EVcharger even if no transaction is recognized by SteVe.

For example, if I setup the box that it starts charging by just plugging in the cable, SteVe does not recognize any changes and does not show me information except "available".

I know that this information is stored somewhere on the box, because if I manually start, it shows me the updated meter reading in the transaction, I just don't know how to access it via OCPP.

I am sorry for my english and hope this was kind of understandable.

Greetings!

in general: most of the time steve relies on and reacts to messages coming from a charger. if the message does not come, steve cannot do much about it.... most of the time. if you have unexpected behaviour, please observe the incoming messages from the charger. that being said:

My problem that I have is, when the EVcharger is connected and I start charging SteVe only shows me the connector status as "available".

by default, steve expects a ConnectorStatus message after a StartTransaction message. the ConnectorStatus message should and will report this connector as busy. afterwards, the connector will not be available in steve anymore. however, we have a configuration flag to change this logic. for each station you can set a yes/no configuration for "Insert connector status after start/stop transaction". if this is enabled, steve itself will set it as busy without waiting on a ConnectorStatus from charger.

But how do I get the current meter reading of the EVcharger even if no transaction is recognized by SteVe.

For example, if I setup the box that it starts charging by just plugging in the cable, SteVe does not recognize any changes and does not show me information except "available".

it's not that a transaction is not recognized by steve. probably the charger does not send a StartTransaction. in my message above i was commenting on "ConnectorStatus message not arriving". your problem seems to be that a StartTransaction is not being sent from the charger.
