Hi,

I'm trying to control my OpenEvse charger with NodeRed using MQTT.

All works fine excent i have no way of telling which rapi out message is being responded to.

ie if i send either

openevse/rapi/in/$GE or openevse/rapi/in/$GT

the responding topic is the same.

##### GT

_msgid: "1539810e.7f8ccf"

topic: "openevse/rapi/in/$GT"

payload: ""

Apologies for resurrecting an old thread, but am in a similar spot and was hoping you might be able to help. I am using NodeRed to test MQTT commands, specifically am trying to alter the charge current using $SC

I tested in the web interface using $SC 12   which returned $OK and set the charging amps to 12. I tried publishing via MQTT Out to a topic *BaseTopic*/rapi/in/$SC and then injected a payload with a string 12

I tried injecting a number 12, and a couple other various things, but don't seem to be able to get the current to change via MQTT.

Answered my own question - For anyone trying to do this in NodeRed it's as simple as passing your id after a : in the payload

ie

:55

I wonder if you could give me an example of the syntax as I can't seem to get it to work.

Thanks

Tom
