Add MQTT API v1 support

[alexebner]

I have configured the Go-Echarger that it ist connected to MQTT. I am seeing a topic ist created with "go-eCharger/001680/status". But the integration does not show any actie entity.

[syssi]

Do you use the default topic prefix or did you change something?

[alexebner]

I have used the default topic in the integration

[syssi]

Perfect! Do you have a linux machine around to verify there is some traffic at the broker

apt-get install mosquitto-clients
mosquitto_sub -h HOSTNAME -u USERNAME -P PASSWORD -t '/go-eCharger/#' -v

[alexebner]

[syssi]

Oh no. This isn't the MQTT V2 API. I assume this is version 1 of the MQTT messages? Could you provide a full dump of the status message? Are there more topics available?

[syssi]

The version 2 of the MQTT API looks like this:

It seems that i have no posibility to activate MQTT V2 API.

Hardware Version2 Firmware 041.0

[syssi]

Could you dump and provide some messages? I would like to support V1 if possible.

[syssi]

In my case it's hardware version 3 and firmware version 053.1.

https://github.com/goecharger/go-eCharger-API-v1/blob/master/go-eCharger%20API%20v1%20DE.md#parameter

[alexkiddde]

Hi syssi, i would love to see V1-support too. Are there any news about that or can i do anything to help you with the implementation?

[syssi]

The most exhausting part of the job is a the entity description per API key. You could help by providing these blocks:

https://github.com/syssi/homeassistant-goecharger-mqtt/blob/main/custom_components/goecharger_mqtt/definitions/sensor.py#L130-L139

We need one description per Home Assistant entity. You can find all API v2 definitions here:

https://github.com/syssi/homeassistant-goecharger-mqtt/tree/main/custom_components/goecharger_mqtt/definitions

[cnu80]

Hi, I also have API Version v1. All entities are unavailable, but I don't understand why. Because some API Calls are the same between v1 and v2.

For example, the reboot counter:

v1 docu:

v2: docu:

Maybe someone can provide an example API Key for v1, and with this information I can try to start with the other api keys. Is it possible to start a new definition file in the definition directory? Like sensors_v1.py ?

Thanks.

[syssi]

Some of the API keys are equal and some are different. The implementation of the API v1 will also be different because the values can be retrieved as bundle (json object) from a single topic. At the API v2 each api key has an dedicated topic.

[hiekkis123]

I seem to have also this version. Any progress on this?

[JakobTewes]

It seems that i have no posibility to activate MQTT V2 API.

Hardware Version2 Firmware 041.0

got the same hardware and firmware combination. would be great, having v1 api supported.

Thanks in advance and regards

Jakob

[peregrines2]

Same problem here V1 support would be fantastic :)

[rolandsteinmeyer]

As a workaround you can configure the go-e charger V1 to use the MQTT Server you may already have running on HomeAssistant and grab the essential values from there. Example mqtt.yaml is attached (you need to merge with your existing mqqt.yaml if you already use mqtt sensors). Replace 012345 with serial number of your charger. mqtt.yaml.txt

[JakobTewes]

thanks for sharing @rolandsteinmeyer. looks promising and can maybe be expanded with other sensors/switches :-)

[eikowagenknecht]

There seems to be another integration for the v1 (but not v2) API.

https://github.com/cathiele/homeassistant-goecharger

Maybe that can be useful in some way for implementing the V1 API?

[JakobTewes]

I went back to exactly this integration @eikowagenknecht and it works really great.

[rene-bayer]

@JakobTewes But this integration has no controlling features :-( I have a HW-V2 with firmware 0.41 here to ... no V2 API support here :cry:

+1 for V1 API Support :pray:

Edit: Bought a HW-V3 and dont regret it :grimacing:
