Hi.

Could you perhaps describe what kostal piko model/version you have tested with and if login is required (or if it's using the default) - or if the api isnt protected at all ?

I followed the instructions, but looks like it's unable to fetch the data.

PIKO 5.5

Hi,

I am having the same issue with Piko 5.5. - would appreciate any help guidance.

I can find all the devices but they are not accessable - I don not get data as it says: "sensor.kostal_piko_autarky_day" - Entity does not have a unique ID

Thanks a lot and best

Sorry for the late response. For some strange reason I do not get any notifications...

For some people in the community it worked, see HA forum but the somebody else in that thread told me that it does not work for him.

I will implement some authentication because up until now it worked without any authentication...

@BastianPlatt you error looks like a different issue to me... maybe you can create another ticket please?

I have implemented this plugin for some people in the community (Home Assistant and a German user forum). I own a PIKO IQ which has a complete different approach to query the data. So I cannot test anything when I make changes and I have to rely on the people who asked me to implement it for them.

I have created a pull request (see #3 to see what I have changed). Maybe you can give it a try with the code from that branch and let me know if it works for you: go to branch Simply replace the files.

I have also updated the read me - is it now better?

@dlorent can you please check the logs at Settings -> Setzings - > Logs? Someboy reported a decoding issue which leads to exactly your described behavior.

@BastianPlatt how have you installed the integration?

@sla89 - Thank you for getting back to us. I will have some time to check within the next few days, and i will get back with the results.

Thanks

@sla89 The problem is probably related to an old kostal piko 5.5 installation of mine, which is from 2012 with a firmware of 3.78. i suspect it's an older firmware which does not support /api access.

So i gues you should just add to the readme which versions it's tested with (and which are known not to work..)

[sla89]

I know from the community that it works for Piko 5.5 and 17.

I started asking the people to tell me which firmware versions they use. So far I know that two people are having a Piko 12, 15 and 17 with the following component version

UI 06.53 FW 06.17 HW 0100 PAR 03.50

and the integration works as-is.

It doesn't work for PIKO 4.2 with firmware version 3.74.

What happens when you call the following url in your browser (replace IP with the IP of your inverter)

http://IP/api/dxs.json?dxsEntries=33556736

Maye you are right and your firmware simply does not expose the data :(

[sla89]

When you press F12 in your browser (edge, chrome or firefox) a new window will open. Can you there select the network tab and visit the webinterface of your inverter, please? Do you see something like this:

If not, your inverter does not expose the data via DXS entries and my integration does not work. You can then try out this integration: https://github.com/rcasula/kostalpiko-homeassistant

I have also updated the README.

@sla89 Unfortuantly not - it's *.fhtml page thats being rendered, no dxs.json at all.

Thank you for the help tho! :)

You are welcome. I close the issue.
