Add Zendure

[andig]

Fix #14797

Note that battery control is not supported. A local api is announced for 2025, we'll revisit then.

[Raudi1]

This doesn't work if the global server is used which many advanced users even in Europe have chosen since it's supposedly more stable and offers newer devices faster etc.
For the global server the URL to get the credentials is:
https://app.zendure.tech/v2/developer/api/apply
So another optional parameter for the server is needed.
And a Hyper V is mentioned. That's not a Zendure product I know of. The Hyper 2000 is a bi-directional home battery+PV system and the Superbase V is a power station.

Thank you, will update asap.

[Raudi1]

I'm preparing a pull request for the template with some additional examples etc. right now.

First off all a HUGE THANK YOU ! To y'all for trying your damn hardest to implement the wishes of the users - you all have my deepest respect. (As I had a peek into the code there was no way in hell i could have accomplished this)

I don't want to be a PIA, but the current "Bad Request error" I get while trying to configure is related to the fact, that currently the EU server is used in general and not the global one - correct?

Error is:
cannot create meter type 'template': cannot create meter type 'zendure': unexpected status: 400 (Bad Request)
regardless if I use the username or the email i registered with.

Probably. Waiting for @Raudi1 if he wants to grab it.

I already did the pull request. But only for the template. I could probably figure the rest out, but it would probably take me a couple of hours at least since I'd have to set up a dev environment and take a good look at all the code first and then do it wrong a couple of times before I get it right. I don't have the time for that right now since I'm a dentist with my own practice. The last quarter is always the most busy.

I still can't add my Zendure device even with the correct server. When I try to validate it, I get the error
cannot create meter type 'template': cannot create meter type 'zendure': unexpected status: 400 (Bad Request)
Oddly enough I can't find anything in the logs even with the level set to trace.

[andig]

I can confirm that the global login doesn't work. EU works find. Maybe the device can only be setup in the matching region?

Working find for me.

[linuxstony]

Normally the device should be found on the corresponding server where the Hyper is connected to - either the global or the EU. Hence the different URLS. It should not make any difference - the response from the server should be the same.

I will try to remove the server on the global one and switch over to the European to see if that works.

Oddly enough I still find MQTT entries from my former tries to get the Hyper connected in my logs although it is not configured in the Yaml or the GUI.

[mqtt ] TRACE 2024/11/18 19:19:31 recv XXXXXXXX/XXXXXXX/state: '{"sn":"XXXXXHYMCFM230063","remainOutTime":398}'

I thought maybe that was my problem that entries are double, but I am not able to remove it at the moment.

I can confirm that the global login doesn't work. EU works find. Maybe the device can only be setup in the matching region?

I have the official MQTT and the ioBroker adapter working. If I use the manual method with
curl -i -v --json "{'snNumber': 'HubSeriennummer', 'account': 'Emailadresse'}" https://app.zendure.tech/v2/developer/api/apply
I get the correct response:
{"code":200,"success":true,"data":{"appKey":"xxxxxxx","secret":"xxxxxxxxxxxxxxx","mqttUrl":"mqtt.zen-iot.com","port":1883},"msg":"Operation successful"}* Connection #0 to host app.zendure.tech left intact

edit: I just set up a testing instance and was able to get the trace log. It still tries to use the EU server, even if I select global in the dropdown:
[zendure] TRACE 2024/11/18 21:07:18 POST https://app.zendure.tech/eu/developer/api/apply
So it's just a small bug in the code. I took a look through it, but I couldn't find anything obvious. But then again, I'm no developer.

[linuxstony]

Sorry - i could have caught that bug - but I didnt - I can confirm this find.

[zendure] TRACE 2024/11/18 22:02:01 POST https://app.zendure.tech/eu/developer/api/apply

[andig]

Ah, region was missing from the template, fixed!

[linuxstony]

Fix works - i was able to add the battery with the nightly build. (I dont use the Hyper as inverter) Thanks @andig!

However @Raudi1 can you confirm that when the Hyper is discharging it is shown as "Batterie laden" instead of "Batterie entladen"?

OutputHomePower should be the value discharging (as in Battery-Output-to-Home-Power)
GridInputPower for charging the battery (as in Grid-to-Battery-Input-Power)

Please correct me if I am wrong.

However @Raudi1 can you confirm that when the Hyper is discharging it is shown as "Batterie laden" instead of "Batterie entladen"?
I will test it next release. Might even add a second Hyper. They just went down a lot. Only around 900€ for the Hyper with 1.92kWh or 2325€ for the Hyper with 7.68kWh and 2 solar panels.
