Hi @MartinViljoen,

I have found my issue!! 

If you check in the logs I send. I did not follow the instructions correct. 

 

Sending to http://http://192.168.0.87:8123

 

So it never manage to send the information to HA. 

Hi @MartinViljoen

Any news on the latest build in Python? Our system got commissioned today and I was hoping to connect it with HA with the new add-on.

Hi There.

Yes its been running for quite some time already --> https://github.com/martinville/solarsynkv3

Also fully supports sending system mode and battery settings.

Hi everybody, first of all, thank you for the time and effort to get SolarSynk running on Home Assistant. I've been using it successfully for some time. I do have a one noob question though, currently I am getting a lot of variables/entities from my inverter, but I am not seeing my Monthly Cumulative PV values. (i.e. how much power was generated by my solar panels, month to date).

I am sure it is available, but I can't seem to find it.

(Basically, I have month to date battery discharge, grid power in for month to date etc, but missing the PV month to date)

Hi Martin

Noticed my v2 addon stopped giving any data back and have just installed the v3 addon, but its giving authentication problems with api.sunsynk.net even though I can log into https://api.sunsynk.net with same credentials.

v2 just logs this

Not sure if anyone else is having the same issue

Thanks in advance

Hi.

Yes there was an issue earlier on. Looks like Sunsynk is preparing to use a more secure authentication method. Both new and old Auth method is now working again. I suspect that soon the old method will be phased out.

FYI when that happens the v2 integration will most probably stop. I don't maintain the repository anymore. V3 on the other hand has already been adapted to the new Auth method. Once the old methos is phased out the new end point will most probably take the place of the original which will again cause a hiccup in V3, but it will be a super quick fix.

Hi,

Are there instructions on how to install v3?

I didn't see any here.

GitHub

GitHub - martinville/solarsynkv3: Integrate your Sunsynk...

Integrate your Sunsynk account with Home Assistant for real-time solar energy monitoring. Track power generation, battery storage, and grid usage while enabling smart automations and custom alerts....

Google's answer:
To install solarsynkv3 for Sunsynk inverters on Home Assistant, you need to add the martinville/solarsynkv3 custom integration repository to HACS, install the integration, and then configure it using your Sunsynk account credentials and Home Assistant details. First, get your Sunsynk Connect username and password, find your Sunsynk Device ID from the app, and note the IP address and port of your Home Assistant instance. Next, add the repository to Home Assistant's HACS, install the integration, and finally, add the integration under your Home Assistant's Settings > Devices & Services. 

My question, does anyone have the entities mapped to the slipx6 solar power card fields?

thanks

Firstly, sorry to semi-hijack this thread, but it seems likely to be the most relevant to what I'm trying to achieve!

I'm UK-based, Easee EV charger, Sunsynk solar set up and HA running on a Raspberry Pi 5.

I'm essentially trying to do three )I think simple...!) things:

1) I want HA to monitor the output of my Easee charger so that when it's charging my car, it pulls solely from the grid, changing the SOC of the batteries, protecting the stored battery power. I'm on a smart tariff with my energy provider and as long as I allow the charger to smart charge when the grid deems fit, it's cheap. I've managed to install the Easee add-on through HACS and have linked my portal account. This now shows the charger activity on my dashboard. (Halfway there...maybe!?)

2) My wife works from home and when she does, more power is used during the day. I'd like to have a button that changes the battery SOC to it lowest possible setting (20%) in order that we aren't pulling from the grid at expensive times. Likewise a button to reverse this.

3) I've seen the amazing cards that have been created showing the energy flow. In an ideal world this would be displayed alongside the aforementioned "Working from home" button, which would make it clear if it's solar or grid that's being used. I currently have no need to store any data for stats or long-term monitoring and am limited my the SD card in the pi for that purpose anyway.

This forum is the most useful source I've found so far, but there's so much information, it's tough to know where to start or if what I want to do is even achievable!

I'll await confirmation of the plethora of errors I've inevitably made!

Thanks.

Thanks,

Google was not quite right - this is an Add-on, not an integration. (I'm still not clear what the distinction is)

But yes, the add-on repository needs adding to Home assistant, then install and configure with your sunsynk username and password, and an access token (I used the same one from the old version).

Then I noticed in the logs that it wants me to create a helper for settings, so followed those instructions.

I then stopped the old v2 add-on

Probably a HA issue, but the friendly name for the old and new entities are the same. I was trying to use the History view to see if it was getting data. It shows me two entities called "Battery SOC", but no way to see the actual entity ID to see which is from v2 and which is from v3

Hopefully the v2 ones will disappear after some time/reboots?

Hmm, I've just realised where the instructions are:

Not here:

An Addon is a docker. Almost like a VM but not quite. ;-)
You dont need hacs, you simply add the repository, refresh you list of addons and install from your addon-store.

I stopped mapping entities between the addon and the slipx card. Reason is simple, too much work to maintain it. 😁
Besides its not possible to provide a direct copy and paste without intervention due to the serial number mentioned in the entity.

With regards to old entities. Make sure the entities are no longer updated by stopping the addon. then give the system a full reboot.
Make sure addon is not set to auto start else it will appear as if they were not removed because it will repopulate the entities after reboot. (Best to un install the addon)

Thanks, yes I've removed the old addon, all seems to be fine. Thanks

As for the distinction between Add-on and integration. It is more from the Home Assistant POV, what is the difference.

To my mind Octopus, Hive etc are doing a similar job to SolarSynk - talking to some cloud API and updating entities etc.
Yours is an add-on and others are integrations. I'm just curious why there are two mechanisms for doing seemingly similar jobs, and what the pros and cons of each are.

Anyway, thanks for the hard work you've put in to this!

HI,

I'm very new to HA and am currently trying to set up this awesome V3!

I've managed to get it to log in with my cloud details, but when it runs, the log gives out this message:

Inverter Settings fetch complete

All API calls completed successfully!

Checking if settings can be processed and flushed...

URL --> http://supervisor/core/api/states/input_text.solarsynkv3_********_settings

All Done! Waiting 60 seconds to rinse and repeat.

Like I say, I'm really new to all this and I'm not sure where to start with trying to fix this...!

Thanks.

Go to Settings --> Devices and services -- Helpers Tab
Create new helper, select "Text" as the type and call it solarsynkv3_********_settings be sure to replace the redacted text with your inverter serial.

Entities created via the API are static and unmanageable, therefore it requires you to manual create it.

Sunsynk is now using a more secure authentication using certificates. Does this add-on work?

Thanks

Hi @MartinViljoen not sure if this was discussed already but I get No Permission errors. Is this due to SunSynk auth?

Hi

Anyone experiencing issues with integration connectivity to the cloud API? From last night?

Values not updating but sunsynk app is correct.

Login error, failed to retrieve bearer token. Running v3

Just checking if the above reported issue is linked to this and what change is needed in V3 to fix?

Thanks for support.

All sorted. Fix with new version released. Awesome...

On another issue, the logs show the following error:

Error: Unable to connect to Home Assistant Settings via the API HTTP Error: 404. Settings will not be processed or applied. Please create a text entity manually named:....

I don't intend writing back settings to the inverter. Should I worry about above or just leave.?

There was an issue with the Addon today , SunSynk enhanced their security and the addon had to be adapted.

If you wont write settings back , You can just ignore the message it wont do any harm. But if it bothers you just create the Helper entity.

Hi @MartinViljoen there is not maybe a sensor that shows when last the script ran or refreshed or when the logger last updated?

Not sure if I am blind or if it is not there.
