Authentication broken for SAJ API

[connornz]

Hi, trying to add my B2-HV system to HA but getting invalid credentials when trying to add the intergration. Is there a problem with the integration with the new API or is it me?

[davidjbwatson]

I am having same issue for a week now.

[faanskit]

I no longer have a SAJ inverter, but it looks like SAJ eSolar has changed login. The login link the integration use responds with 302.

It looks like they have moved the login and in the portal they seem to add CAPTCH for some market.

Likely this integration will no longer work due to this.

The other SAJ integration seems to have same/similar issue:
djansen1987/SAJeSolar#72

Please try it instead.

Since I don't have a SAJ inverter it is unlikely I will spend time on this...

Feel free to nominate someone to continue this work...

That was my assumption as I noticed login page was different. I tried other saj integration (which I had before yours) . As you replied no go shame . Thanks for your reply .

How do I find someone who could fix this issue?

[faanskit]

There are some forks made, check with the owners of the forks if they have a solution.
We use undocumented reverse engineered API's towards Saj in this integration, and Saj can change at any time (like they now did).

I noticed that they also started with CAPTCHA for some regions now, so likely soon it will completely break.

You can always ask Saj to publish API's...the more who asks, maybe one day they will support it. SolaX did it after community push.

As SAJ is (partial) a chinese company, I think we can forget about a public API. My integration is currently still working, fingers crossed that it stays like this.
If mine ever breaks I might check to fix it but I'm not an expert in this program language.

@robshot do you have a link for your integration?

[faanskit]

@robshot do you have a link for your integration?

It's in the first sentence of the README to this integration :-D

Here:
https://github.com/djansen1987/SAJeSolar

[RobbieDemaegdt]

I mean the integration in my HA, I'm using this intergration in my HA as I helped faanskit with debugging some things.

[walkjivefly]

ha ha, yeah, bit of a misunderstanding here. I thought @robshot was saying he had a separate HA integration (fork or whatever) that was still able to connect to the SAJ API.

This is an old issue, but the API authentication is not broken. The problem is that SAJ provides two nodes:

This application defaults to the EU node, while the international node has different URLs.

I'm working on a fix and will submit a PR, but the easy hack is to go to your custom_components/saj_esolar_air folder and edit esolar.py lines 11 and 12 and replace it with:

BASE_URL = "https://intopapp.saj-electric.com/sajAppApi/api"
BASE_URL_WEB = "https://intop.saj-electric.com/saj"

Also remove the pycache folder under the same folder. Restart homeassistant and reconfigure it again. It worked just fine for me..

[faanskit]

@lucianor if you want to take over this repository, let me know and I´ll transfer it to you or make you an admin.
I am no longer using SAJ and will not maintain it.

[lucianor]

I just added a PR to fix the region switch problem, so this bug can be closed.
@faanskit please DM me and let's talk about your component. I would like to discuss some things you did before I take over.

[lucianor]

@djansen1987 is another good candidate to maintain this. It looks like he did not fork so now I'm trying to compare his repository with this, but his code structure is different. His field handling however is better. So I think we need to combine the two somehow. If @djansen1987 is game, so am I.

[djansen1987]

Hi for me goes the same, I only created the integration because of a family member. It currently does everything he needs. If some one wants to take over be my guest. Only requirement I have is it should be backwards compatible so the current 106 users won't lose their history data (longterm data which is held to the entity id)
