Cerbo GX / Venus OS : Creation of a Generic EV Charger via MQTT failed

Hi,

I’m trying to create a generic EV Charger entry in my Cerbo GX (Venus OS V3.33). I have enabled both MQTT SSL and MQTT Clear Text, and I am able to connect via MQTT Explorer and publish messages successfully.

According to other posts and the documentation, to add a « EV Charger » I should send the following payload to the topic device/fe001/Status:

{ "clientId": "fe001", "connected": 1, "version": "1.0", "services": { "ev1": "evcharger" } }

After doing this, I should receive the device instance and respond on device/fe001/DBus.

However, nothing happens. Am I missing something required to allow new devices from MQTT on my production Venus OS?

PS: I know I will have to send other messages after the creation, but I didn’t receive any Instance ID from the VenusOS.

Thanks a lot for your help.

I think what you want to achieve is not a standard feature and will only work in conjunction with this: GitHub - freakent/dbus-mqtt-devices: A driver for Victron VenusOS GX devices to support use of dbus-mqtt/flashmq-mqtt

Thanks for the quick feedback… I see. I think you are right.

Since I don’t want to customize the Cerbo, I guess I’m stuck

Well, yes…I think the concept shown in that github extension is a wonderful opportunity to make the victron ecosystem more flexible.
So best suggestion iis, to open a feature request with victron…there’s a section / tag in the forum right here :wink:
