Hi everyone.
I have created this topic to collect requests for Homey OCPP server app.
Based on the interest, we will prioritize the feature requests.
Hi, promising app!! It would be great if it can be combined with using a backoffice for reimbursements
The app is already available and I think it was ment that this is the app-topic.
I took the liberty as a moderator to update the title and first post to reflect this and a cleanup on the misunderstanding.
Hello @DnetLabs, I have a Huawei Smart Charger, this are the settings for OCPP protocol below:
Does it work with your app? Where would I put the URL when adding the device?
See link with the documentation of supported commands: https://ske-solar.com/fileadmin/user_upload/Guide_SCharger-7KS-S0_OCPP-1.6_Protocol_EN.pdf
Thanks
Hi
We dont have the same charger but I had a look at the pdf, you can try:
- Install the app
- Add device
- Note the IP and port thats is shown at Homey OCPP Server app
- In your EV charger:
Domain Name: the IP you see at step #3, e.g. 192.168.1.11
Port: 9000
user pass: leave blank
Cheers

Hello,
So I configured the setting but there is no way to leave the user/pass blank. Any option on your server to accept any username that is being sent regardless? I think I can leave password blank at least
The app doe snot support user/pass yet.. most probably your physical charger is requesting a user/pass as min security so will not work.
You can try and let us know 
I will capture this as a feature request, thanks.
Thank you for this hope it is an easy development 
Hi,
As discussed by email, I’d like to request support for a true charging pause by setting the charging current to **0 A (or 0 W)**while keeping the OCPP transaction active, instead of sending a RemoteStopTransaction.
This would make solar surplus charging possible without requiring the EV to be unplugged and reconnected.
I’m happy to test a beta version with my CTEK Chargestorm Connected 2.
Thanks Stefan this is a useful feedback and we implemented it and thank you for testing and confirming that it works.
We are submitting it to certification now so that everyone can benefit.
Hi!
Thanks for the app!
I would appreciate something that replace the statistics from common ocpp servers in the cloud. I.e. if you could find a way to show session statistics. I.e. timeline logs or something more advanced of each session. I.e. start time, stop time, kWh charged would be great to have!

Hi Most likely the charger simply isn’t sending the power/current/voltage values. In OCPP there’s a setting called MeterValuesSampledData that controls which measurements the charger reports, and chargers often defaults it to energy only. Two quick things to check:
- Are the readings blank while actively charging? Most chargers only send live measurements during a session, so a plugged-but-idle charger showing 0 is normal.
- If it’s still blank mid-charge, the charger’s
MeterValuesSampledDataconfig likely doesn’t include power/current/voltage.
I can have the app ask the charger to send those values automatically on connect, so you won’t need to touch any charger config but it will only work if CTEK supports it.
This is tricky, as we cannot query server side BUT we can add info on timeline that shows how much a session charged in stop message notification.
Can you send me a message from OCPP Server app page, clicking to Suggestion link so I can send you a test app?
Since it was reporting sessions to its vendor cloud service, the box have abilities, it’s just a matter of understanding all the configuration values.
I have now turned on that it should report all possible data all the time, and also a bunch at a sample rate of 60s.. I hope it’s not causing too much traffic to homey.
But if there also is a way to ask for the values the ocpp server would like to have, and can handle, perhaps it doesn’t hurt to do that?
Yes, by telling the box to send these values, I get a lot more on the homey device status page at charging, and also the summary on the icon. Problem solved.
Thanks, suggestion sent.
I noticed that this ctek box likely also support mqtt for statistics (read only). Will explore at another time.
Hi,
I have a Garo GLB+ that I connected to the app and it seems to work. I can start and stop charging and I get all the statistics when charging. But I’m a bit confused on the slider used to set the output power. I’t seems that I need to set it before I start to charge. If I adjust it during the charge nothing happens. According to the box documentation it should support “Operator Current Limit” and that parameter should be possible to change during a charge. Is this the parameter that the slider chages or is it something else? Is there any difference between using the slider or adjust the power in a flow?
Hi;
Good to hear that it works with Garo GLB+.
The slider does control the Operator Current Limit (it sends the charger a charging-profile current limit over OCPP).
The thing is how we currently send it: as a “default profile,” which chargers like your Garo only apply when a session starts so changing it mid-charge is ignored.
To adjust the limit during an ongoing session, it needs to be sent as a “transaction profile” tied to the running session, which the Garo does support live.
i will add this to our feature request backlog, and will include this to the next release
And to your second question: there’s no difference between the slider and setting power in a flow as they’re the same control under the hood, so both will benefit from this fix with the next version.
ETA for the next version: September.
