Technically the pro model should work with the same functionality as the Gemini models, so they could be paired with Homey. However it is untested and pro-specific features are not supported at this time. I need some funding arranged to get my self also a Pro model to be able to add any additional functionality for it.  
See first post about how to support.

Hi! i have two EV’s. Leaf and Polestar. I need to change phases and amperes for the night depending witch car is connected. I tried Homey Polestar app but it´s no good for this. Could this be solved with RFID- tags? I tried but I couldn’t figure out how.

There is a User Card capability tag available for go-e Chargers using v2 API. However there are no events yet for it (no triggers). You could use Device Capabilities app to monitor the change of that capability.

Doesn’t look like there is any API-changes that would impact.

Hello,

I’m looking for an example of an advanced flow for Go e Gemini EV-charger with loadbalancing. On the P1 port of my digital counter, I have a Homewizard-dongle. I would limit the peak current of my total house consumption, while loading my electric car. I would also have the option to limit the load capacity - for example: loading has to stop at 90% of the battery capacity. And I have also another very important question: what to do with the Go e app on my mobile?

Thank you so much for your help!

</div>

There are several topics in this forum for generic load balancing flows. Such flows examples can be used in your case.

@Picsou621 has had great success in optimizing. For example have a look at [Charging EV with Advanced Flows](https://community.homey.app/t/66223) .

One note, that the EV charger does not know what is the percentage of charge in the car. You would need a car make/model specific app to read the state of charge.

helllo, it seems that it’s not working with new go-e charger pro core or I did something wrong. I allowed API v2, I was able to add device to homey but all values are empty - not updating

From Homey Mobile app, please go to … More → Apps and find the go-e Charger app. Then go to settings of the app from the gear icon and Create Diagnostic Report.

Hopefully the log will give me some idea why is not working.

Additionally, if you could check how it advertises itself in the network:

> **[go-eCharger bonjour discovery with mDNS-DS · oh2th-homey com.go-e.charger ·...](https://github.com/oh2th-homey/com.go-e.charger/discussions/7)**
>
> To verify if your go-eCharger is automatically discoverable on your network, you can use Bonjour Browser on Windows and Discovery on macOS. On the CLI in MacOS or Linux there is dns-sd tool. Find t...

It could be that it is not recognized as it is a new model.

Thank you, that will help me to introduce the model specific driver. But it won’t fix your problem.

based on the diagnostics report, the app is connecting to the go-e charger, but gets a “bad request” response from it.

Please try this and replace the IP-ADDR of your go-e Charger  
[http://IP-ADDR/api/status?filter=sse,fna,car,alw,acs,frc,trx,err,wh,pha,nrg,eto,tma,amp,ama,cbl,fsp](http://IP-ADDR/api/status?filter=sse,fna,car,alw,acs,frc,trx,err,wh,pha,nrg,eto,tma,amp,ama,cbl,fsp)

That should return a JSON formatted response. If not, then the API is not activated properly with the go-e mobile app.

Hmm, this is becoming interesting. I will need to contact go-e to get some information on why the new Core/Pro models rejects the request when called from the app, but not from a browser.

Could you share your HomeyScript. It just might help. There is something with the http request generated in the app making the charger to reject it.
